INTRODUCTION The California Department of Transportation (Caltrans) updated the 2014 Real-Time System Management Information Program (RTSMIP) compliance report for Interstate routes and combined it with the 2016 RTSMIP for metropolitan area routes of significance (RoS). The combined report demonstrates conformance with the federal regulations for accurate and available traffic and travel conditions reporting statewide on Interstate highways and metropolitan area non-Interstate highways, or RoS. The RTSMIP provides accessibility to traffic and travel conditions information by public agencies, the traveling public, and other parties who deliver value-added information products. The Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) Section 1201 (a)(1), (a)(2) and (c)(1) final rule published in the Federal Register on November 8, 2010, requires the State Department of Transportation (DOT) to develop a RTSMIP meeting the requirements as outlined in title 23, Code of Federal Regulations part 511 (23 CFR 511). The RTSMIP is defined as the program by which states gather and make available data for traffic and travel conditions on Interstate highways and RoS. These conditions refer to the traveling public’s experiences on roadways, with the emphasis on the following four areas: construction activities, roadway or lane-blocking incidents, roadway weather observations, and travel time information. For construction activities and travel time information, the regulations define metropolitan areas as geographical areas designated as Metropolitan Statistical Areas (MSAs) with a population exceeding one million inhabitants. Compliance with federal regulations to the four provisions is measured by the accuracy and availability of the reported information. The accuracy of information measurement is 85 percent accurate at a minimum, or a maximum error rate of 15 percent. The availability of information measurement is 90 percent available at a minimum. The program provides the capability to monitor traffic and travel conditions of the major highways across the United States in real-time, as well as a means of sharing data with state and local governments, and the traveling public. The RTSMIP is designed to use existing traffic and travel condition monitoring capabilities, build upon them where applicable and complement current transportation performance reporting systems, making it easier to gather and enhance required information. Data quality standards are to be established for data to the consumers. The program includes participation from highway agencies, public safety agencies, transit operators, and other operating agencies necessary to sustain mobility. The Intelligent Transportation Systems (ITS) Architecture was evaluated and explicitly addresses needs for real-time highway and transit information, and the methods to meet these needs. The ITS Architecture features the components and functionality of the program while focusing on coverage, monitoring systems, data fusion, accessibility to highway and transit information, and value-added information product providers.

The effective date of the RTSMIP for traffic and travel conditions on Interstate highways was November 8, 2014, and is November 8, 2016 for RoS. This report establishes Caltrans’ compliance with 23 CFR 511 and addresses conformance with regard to construction activities, roadway or lane-blocking incidents, roadway weather observations, and travel time information on Interstate highways and RoS. Emphasis is placed on accuracy of information measured at 85 percent or higher, and availability of information measured at 90 percent available or higher. Caltrans’ ITS Architecture is also compliant with federal regulations.

I. PART A: 2014 INTERSTATE ROUTES

1. CONSTRUCTION ACTIVITIES (INTERSTATES) Federal regulations require state DOTs to provide traffic and travel conditions through the RTSMIP. The timeliness for the availability of information regarding full construction activities that close or reopen roadways or lanes will be 20 minutes or less from the time of the closure for highways outside of metropolitan areas, and 10 minutes or less from the time of the closure or reopening within metropolitan areas. Intermittent or short-term lane closures of limited duration that are less than the required reporting times are not regulated for compliance in this provision. Caltrans uses two tools to report, monitor, and status construction activities on Interstate highways. The first tool is the Lane Closure System (LCS), an Oracle database that contains all information related to planned lane closures for all 12 Caltrans districts. The second tool is QuickMap, a web page that is updated every five minutes with real-time traffic information feeds from various data sources, including: Caltrans’ Commercial Wholesale Web Portal (CWWP), Changeable Message Signs (CMS) content, the Caltrans Highway Information Network (CHIN), the Transportation Management Center Activity Log (TMCAL), and the LCS. Caltrans uses QuickMap to make real-time traveler information available to motorists. Caltrans demonstrates compliance with construction activity regulations by reporting all planned lane closures on Interstate highways to the Transportation Management Center (TMC) before the first advanced warning sign is placed on the roadway. This process is referred to as “10-97.” When the TMC staff member is notified and inputs “10-97” into the LCS, a traffic device icon appears in QuickMap with estimated end times and dates for the planned closure. At the end of the planned closure, the TMC is notified after all of the advanced warning signs are removed from the roadway. This process is referred to as “10-98.” When “10-97” and “10-98” are reported to the TMC within the specified end times and dates, the lane closure is considered “accurately statused.” If either a “10-97” or a “10-98” occurs without the reciprocating activity, this is considered “not accurately statused.” For construction activity compliance, Appendix A provides compliance reports for statewide planned lane closures on Interstate highways for a three-month period from January through March 2015. For planned closures, approval must be obtained from the District Traffic Manager (DTM) one week before the closure takes place. Once approved, the closure is posted in the LCS and becomes active before the first advanced warning sign is placed on the roadway. The lane closure is considered complete after all of the advanced warning signs are removed from the roadway. Emergency closures do not require DTM approval and are entered into the LCS immediately upon notification by the TMC staff member.

Caltrans uses QuickMap, the LCS and CMS to disseminate real-time system information as follows:

• QuickMap is a web-based map which displays current traffic speeds, roadway incidents, full closures, lane closures related to construction, active CMS, CCTV (Closed Circuit Television) camera images, and chain controls. The Headquarters (HQ) Traveler Information Coordinator and the Public Information Officer (PIO) manage the information shown on QuickMap.

• The LCS is an Oracle database which contains start and end times related to planned lane

closures for all 12 districts. The Statewide Lane Closure Management Coordinator manages LCS.

• CMS may be used to inform travelers about active construction activities on highways.

The LCS disseminates construction information to QuickMap, the CWWP, the Performance Measurement System (PeMS), and the CHIN. The lane closure data files in QuickMap and the CWWP are updated every five minutes. In terms of accuracy, the LCS is up and running approximately 99 percent of the time (excluding a daily 15 minute routine maintenance period). The real-time information availability for lane closures from all districts exceeds the 90 percent threshold. Of the 12 Districts, the TMCs in District 1, 2, 5, and 9 do not operate 24 hours per day, 7 days per week. When these districts have a planned lane closure scheduled after business hours, the lane closure is entered into the LCS by one of the neighboring districts. For scheduled planned lane closures that occur after the TMC business hours, District 1 notifies District 4, District 2 notifies District 3, and Districts 5 and 9 notify District 6. Due to intermittent cell phone coverage in rural areas, there may be occasions where planned lane closures are not statused within the 20 minute timeframe as stated in the regulations. These occasions are rare and Caltrans is currently exploring the use of LCS mobile applications with broadband coverage allowing field personnel to status lane closures remotely.

2. ROADWAY OR LANE-BLOCKING INCIDENTS (INTERSTATES) Federal regulations require that the availability of information related to roadway or lane-blocking traffic incidents to be 20 minutes or less from the time the incident is verified for highways outside of metropolitan areas. The availability of information related to roadway or lane-blocking traffic incidents within metropolitan areas will be 10 minutes or less from the time the incident is verified. Caltrans uses the following tools to report, monitor, and status incidents on Interstate highways: the TMCAL, the Advanced Traffic Management System (ATMS), the Intelligent Roadway Information System (IRIS), and the California Highway Patrol Computer-Aided Dispatch (CHP CAD).

• The TMCAL is a MySQL statewide database where incidents are logged and fed into QuickMap. From the time a roadway or lane-blocking incident is reported to the TMC, the latency between the incident reporting and the data entry into the TMCAL by staff is minimal and within the 85 percent accuracy threshold. After the incident is entered into the TMCAL, the process to store and disseminate the information is automated.

• The ATMS is a statewide database which uses ITS elements to gather real-time

information on State highways and distribute the information to the district TMCs.

• The IRIS is a statewide database used to monitor incidents on State highways.

• The CHP CAD is a statewide database where local dispatchers enter incident information gathered from officers in the field. The CHP CAD feeds real-time incident updates to the TMCAL, which in turn feeds the incident into QuickMap.

• The CWWP houses data and makes it available for government and local agencies, cities,

counties, and the public. Caltrans disseminates traveler information through the CHIN IVR number 1-800-427-7623 (1-800-GAS-ROAD), QuickMap, the CWWP, and CMS signs. The CHIN IVR, QuickMap, the CWWP, and the general messages for the CMS are managed by the HQ Office of Traffic Management. The accuracy and availability of roadway and lane-blocking incidents by Caltrans meets or exceeds the requirements through the TMCs that are staffed and managed 24 hours per day, 7 days per week, and through the use of an automated system which populates the TMCAL database. Incidents occurring in districts that are not continuously operational are reported to the neighboring TMCs that function 24 hours per day, 7 days per week. The TMCs also have reporting policies to local entities as appropriate and required, and also report with the neighboring TMCs when an incident affects more than one district.


7

For roadway and lane-blocking incidents, Caltrans and the CHP work together to monitor and report highway conditions. The CHP uses the CAD to track all accidents on the State Highway System (SHS). The dispatcher enters the information into the CAD as soon as it is obtained from the reporting party. Typos are generally corrected immediately after the information is entered. The Media CAD, a limited subset of the CAD determined for public consumption by the CHP, uploads the information in five minutes or less. The process is subject to human error yet is generally very accurate and meets the federal regulation’s 85 percent minimum accuracy threshold. The Media CAD is never off-line and is 100 percent reliable and available. It has back-up servers and four hubs; therefore, updates and routine maintenance are completed one hub at a time. The Media CAD meets the 90 percent availability requirement as outlined in federal regulations. The incident reporting Standard Operating Procedure (SOP) is that the CHP enters the information into the CHP CAD which is then released to the Media CAD and the CWWP. If the event is reported by a CHP field officer, it is considered verified. If it is relayed by the public via 911, there needs to be either multiple 911 calls, verification by CCTV, or field verification by the CHP or Caltrans personnel before it is considered verified. When confirmation is received that the event is no longer affecting the roadway, the incident is closed out in the CAD and the CWWP no longer shows the event. In general, the information entered by the CHP is in the CWWP before Caltrans is aware there is an incident. The latency between the CAD and the CWWP is small (approximately five minutes); therefore, the event will always be available to the public within approximately five minutes. Caltrans does not have the ability to affect “false data,” meaning data that may exist even though there is no actual event. Caltrans utilizes CCTV and/or Caltrans field personnel to verify there is no incident, or that an incident has been completed, at which point Caltrans relays the information to the CHP who in turn closes the incident, effectively removing it from the CWWP.

3. ROADWAY WEATHER OBSERVATIONS (INTERSTATES) Federal regulations require the availability of information about hazardous driving conditions and roadway or lane closures or blockages due to adverse weather conditions to be 20 minutes or less from the time the hazardous conditions, blockage, or closure is observed. Caltrans reports weather statewide using similar weather-related tools: the CHP CAD, the Road Weather Information System (RWIS), the Fog Detection and Warning System (FDWS), and Chain Controls. Once the data is gathered or reported it is entered into the CHIN. Data can be entered into the CHIN using the TMCAL or by the Headquarters Communication Center (HCC) receiving a call, facsimile, or e-mail, and manually entering the data. From the time the TMC is notified, the process is fully automated with a Mean Time Between Failure (MTBF) that meets the required accuracy.

• The RWIS consist of networks of weather monitoring stations that collect weather condition data on roadways. The system is comprised of Environmental Sensor Stations (ESS) in the field, a communication system for data transfer, and central systems to collect field data from numerous ESS. These stations measure atmospheric, pavement, and/or water level conditions.

• The FDWS consists of visibility sensors, speed detectors, and cameras to detect

congestion and visibility problems that could affect driver and passenger safety on roadways. Through intelligence built into the ITS product, the system alerts motorists automatically of adverse weather conditions and slow speeds by using CMS and Highway Advisory Radio (HAR). The installation is 40 percent solar-powered, using both point-to-point and point-to-multipoint wireless radios to provide network connectivity. Local field controllers allow the field equipment to work autonomously should a break occur in communications to the central system.

Caltrans provides real-time roadway weather information on Interstate highways through three sources: the IVR, the CWWP, and the Web. Additionally, TMCs have reporting protocols to local entities as required. When adverse weather conditions cause lane closures, Caltrans personnel relay the information to the TMC dispatch and similarly update the TMC when the closure is removed. The TMCs and Maintenance Dispatch report incidents as identified in the Highway Conditions Reporting Matrix to the HCC within 10 minutes of notification of the incident, as well as to their district executive management. The Traffic Management Team (TMT) may also respond to a weather-related road closure, and can perform a travel run to determine delay time.


9

Inter-agency coordination between Caltrans and the CHP occurs in the event of a major storm that closes the highway. The CHP performs escorts prior to the closure and Caltrans is responsible for putting the closure in place. The incident information is reported to and received by the TMC, and a dispatcher enters the data into the TMCAL, which is disseminated to the public. The TMCs operating 24 hours per day, 7 days per week have negligible system down time, and exceed the 90 percent availability requirement (except in the case of a power outage). Caltrans districts get their weather information from similar sources and then enter this information into the CHIN. The TMC will relay the information to the HCC, and staff will then either enter the data into the TMCAL, or directly into the CHIN. All districts use weather information from the CHP CAD, Caltrans maintenance supervisors, and the National Oceanic Atmospheric Administration (NOAA) for roadway weather. Districts 1, 2, 3, 6, 8, 9, and 10 collect the RWIS weather data. Districts 2 and 3 use the TMCAL to populate the weather information to the CHIN. The other districts input the data manually into the CHIN. District 10 plans to switch to the TMCAL in the future. District 11 has a system designed to automatically post any information to the CHIN. Appendix B shows a detailed summary of roadway weather tools and observations by district, and also discusses the accuracy and availability of roadway weather real-time information. Both Caltrans and the CHP jointly decide when to close Interstate highways due to adverse weather conditions. Either Caltrans or the CHP will initiate the discussion based upon on site visual inspection of the conditions on the facility. The closure is then reported to the TMC and the CHP dispatch. The TMC and the CHP place this information into their databases and tracking systems.

4. TRAVEL TIME INFORMATION (INTERSTATES) Federal regulations require the timeliness for the availability of travel time information along limited access roadway segments within metropolitan areas to be 10 minutes or less from the time the travel time calculation is completed. For the purposes of reporting real-time travel information, Caltrans has divided the State into five metropolitan regions: Sacramento, Bay Area (San Francisco and San Jose), Los Angeles, Riverside, and San Diego. Appendix C is a statewide graphic of the highlighted regions. Throughout the metropolitan areas of California, Caltrans utilizes CMS to provide real-time travel information on Interstates. All five regions are in federal compliance and real-time travel information is provided on at least one Interstate route in each metropolitan region. For travel time compliance, Appendix D lists all CMS statewide displaying travel time information on Interstate highways by district, county, route, postmile, direction, and CMS location. In November 2014, the Federal Highway Administration (FHWA) made an observation and recommendation for the 2014 RTSMIP compliance report:

• Observation: “The report indicates many of Caltrans’ districts responsible for a Metropolitan Statistical Area (MSA) have an alternative to providing travel times on Changeable Message Signs (CMS). When loop detection is poor, districts shut off the CMS or use them for a different operational purpose. In California, the data feed from CMS operation is the link to Caltrans’ QuickMap and other third party messaging applications. In other words, when the CMS is dark during periods of traffic congestion, there are no other means to transmit travel time information to Caltrans’ application because the CMS display is the primary source used to broadcast travel time to other systems. This could impact Caltrans’ ability to meet the information availability portion of 23 CFR 511 in the future {Refer to 23 CFR 511.309 (4) & (6)}.”

• Recommendation: “Caltrans’ public performance report The Mile Marker contains a

statewide goal of having 90% or more vehicle loop detectors functioning properly. As such, Caltrans should consider having each district managing an MSA achieve an intermediate milestone in pursuit of the overall statewide goal of 90% functionality. In addition to pursuing your loop detector health goal, Caltrans should consider the methods Caltrans’ District 4 and District 8 are currently implementing to use real-time data from additional technologies as an alternative approach to vehicle loop detection.”

To ensure compliance with federal regulations, Caltrans will enhance the data strategy for travel times to address the FHWA’s observation and recommendation. Travel time algorithms would be automatically generated and sent directly to the CWWP. By automatically sending the travel time algorithms directly to the CWWP, the travel times will not have to be initially posted on a CMS. Expected implementation of this data strategy is within three years.

Interstate Travel Time Information – Sacramento Region (District 3)

• El Dorado, Placer, Sacramento, and Yolo Counties

• Cities of Sacramento, Roseville, and Arden Arcade

• The Metropolitan Planning Organization (MPO) for the Sacramento Region is the Sacramento Area Council of Governments (SACOG).

District 3 displays travel times on Interstate highways with updates provided typically at five minute intervals. The travel times posted at CMS locations are initially verified with field staff driving the segments to ensure accuracy. Travel times are verified by driving the route using a tachometer to confirm the actual time information. A tachometer is a device used to estimate traffic speed and volume. A vehicle is equipped with a sensor and “tach runs” can be completed to record the traffic data. The TMC operator staff checks posted travel times along with the other posted CMS messages in the district. If a travel time appears unusual, the operator will check the camera and PeMS data to ascertain if there are reasons to explain the unusual posted travel time. As a fail-safe measure, if more than a three mile segment of detection is not functional, the system will stop displaying travel times and the CMS location will be blanked. Therefore, the system improves accuracy by not operating if there is not adequate detection. The availability of a CMS location for posting travel times encounters interruptions only in the following cases: incident management, construction traffic management, and emergency notifications such as America’s Missing Broadcast Emergency Response (AMBER) for missing children, and Blue Alerts, which assist in the apprehension of violent criminals who kill or seriously injure law enforcement officers. Over a three-month period, CMS locations operated greater than 96 percent of the time. Non-operational CMS locations are reported timely to the Electrical Systems Branch for investigation. Once an operator notes that a CMS is blank instead of displaying travel times, the location is reported to the Electrical Support Systems Branch for investigation. Any necessary field repairs are submitted to maintenance through the Integrated Maintenance Management System (IMMS). Travel time information displayed on CMS for Interstate highways in the Sacramento Region is illustrated in Table 1.

Interstate Travel Time Information – Bay Area Region (Districts 4 and 5)

• Alameda, Contra Costa, San Francisco, San Mateo, Marin, San Benito, and Santa Clara Counties

• Cities of San Francisco, Oakland, Hayward, San Jose, Sunnyvale, and Santa Clara

• The MPO for the Bay Area Region is the Metropolitan Transportation Commission

(MTC). District 4 uses data provided by the MPO-MTC partnership. The MTC has purchased traffic data from INRIX using Global Positioning System (GPS) probe-based traffic data. The source of the GPS data is a combination of Commercial Vehicle GPS Probe, Consumer Vehicle GPS Probe, GPS-Enabled Smartphone Probe, and Cellular Network Probe. The data is fed to the fusion engine which checks and weighs the data accuracy and procedures, and estimates travel times. The technique has been tested by the Washington State Department of Transportation and the New Jersey State Department of Transportation. New Jersey validated the data on the I-95 via a second set of Bluetooth readers. The MTC validates the travel time data via a series of floating car studies. INRIX has over three years of stored data that is normalized for seasonal traffic patterns. The ATMS travel time module for District 4 is programmed on a fixed schedule of 0500 to 2100 hours daily. If the system loses the data feed from the MTC for longer than 10 minutes, the travel time system is programmed to blank out the signs. If the data feed is unable to be restored, there is an option to use the secondary source of data from Caltrans’ traffic monitoring stations. District 5 does not have Interstate routes that qualify for the RTSMIP at this time. Travel time information displayed on CMS for Interstate highways in the Bay Area Region is illustrated in Table 2.

Interstate Travel Time Information – Los Angeles Region (Districts 7 and 12)

• Orange and Los Angeles Counties

• Cities of Los Angeles, Long Beach, and Anaheim

• The MPO for the Los Angeles Region is the Southern California Association of Governments (SCAG).

District 7 displays travel times on approximately 45 CMS using roadway loop detectors. A computer algorithm gathers the real-time loop information and automatically computes an estimated travel time to selected target locations. The CMS are updated every three minutes. To ensure accuracy when no detector information is available, the CMS will not display a travel time for that target location. The travel times are displayed on CMS daily from 0500 to 2100 hours. This wide range of available travel times encompasses 100 percent of the daily congestion period on roadways. The travel times are not displayed outside of this period when congestion and traffic volumes are lower. Due to insufficient detection, designated travel times may not be displayed on CMS, yet the real-time information is available above the 90 percent requirement during the operational time frame. District 12 checks the accuracy of speed which is calculated with the loop detection system, and utilizes radar guns and tach runs to verify traffic conditions. This analysis concludes that the speed calculation is 95 percent accurate. The travel times are displayed on CMS from 0600 to 2200 hours. An algorithm calculates travel time based on real-time traffic speed along a corridor. The algorithm has the intelligence to extrapolate the calculation in the event of malfunction for up to two and a half miles and is 95 percent accurate. Travel time information displayed on CMS for Interstate highways in the Los Angeles Region is illustrated in Table 3.

Interstate Travel Time Information – Riverside Region (District 8)

• Riverside and San Bernardino Counties

• Cities of Riverside, San Bernardino, and Ontario

• The MPO for the Riverside Region is the SCAG. District 8 currently displays travel times on 35 CMS on Routes I-10, I-15, I-215, as well as other state routes between 0500 and 2000 hours. The overall PeMS detector reliability has been difficult to measure due to ongoing construction activities and wire theft, which lowered the number of available detectors. Caltrans purchases third party data which is integrated into the central freeway management system; therefore, travel times are not affected by failed detection. The 85 percent accuracy is easily attained and verified through tach runs. The freeway management system has an uptime that exceeds 99 percent. The only factor that affects the availability is the status of detection. The availability will be measured through the PeMS. A log of all the messages and the times they were posted is maintained in the database. The availability of existing signs that are outside of construction zones exceeds 90 percent. The purchase of third party data will allow for travel times to be posted where detection is unavailable. Travel time information displayed on CMS for Interstate highways in the Riverside Region is displayed in Table 4.

Interstate Travel Time Information – San Diego Region (District 11)

• San Diego County

• Cities of San Diego and Carlsbad

• The MPO for the San Diego Region is the San Diego Association of Governments (SANDAG).

District 11 achieves travel time accuracy by verifying the routes and calculated travel time as needed by driving pilot vehicles to identified destinations during various hours of the day. Once the calculated travel time and the driven travel time are within one to two minutes of each other, the destinations are displayed on CMS. The travel times are verified in lane number two at the posted or prevailing speed (if below posted speed). Travel times are displayed on commute routes Monday through Friday during commute hours: 0500-1000 and 1400-1900 hours. The travel time destination display data depends on the performance of vehicle detection stations, and the reliability of detection data is over 90 percent. Travel time information displayed on CMS for Interstate highways in the San Diego Region is displayed in Table 5.

5. ITS ARCHITECTURE (INTERSTATES) Federal regulations require all states and regions which have created a Regional ITS Architecture to evaluate their Regional ITS Architecture to determine whether the architecture addresses real-time highway and transit information needs, and the methods needed to meet such needs. The regulation further states that Regional ITS Architectures shall feature the components and functionality of the RTSMIP. The California Statewide ITS Architecture (SWITSA) contains a blueprint for deployment of ITS projects that fall within the category of statewide and interregional ITS services related to regional integration and cooperation among stakeholders. The SWITSA was developed in 2004, updated in 2010, and is currently undergoing an update. The update will include deployment of the ITS SystemBuilder tool, which will enable users to view the SWITSA and all other Regional ITS Architectures within the State. The SWITSA includes the following regional service packages that support the RTSMIP established in accordance with 23 CFR 511.

• MC10: Maintenance and Construction Activity Coordination supports the dissemination of maintenance and construction activity to information service providers (ISPs) who can provide the information to travelers.

• ATMS08: The Traffic Incident Management System manages both unexpected incidents

and planned events so that the impact to the transportation network and traveler safety is minimized.

• MC03: Road Weather Data Collection collects current road and weather conditions using

data collected from environmental sensors deployed on and about the roadway.

• MC06: Winter Maintenance collects current road and weather conditions using data collected from environmental sensors deployed on and about the roadway.

• ATIS1: Broadcast Traveler Information collects traffic conditions, advisories, general

public transportation, incident information, and roadway maintenance and construction information; and broadly disseminates this information through existing infrastructures.

• ATMS06: Traffic Information Dissemination provides driver information using roadway

equipment such as CMS or HAR. The user service packages referenced above represent a subset of a more comprehensive list contained within the SWITSA. The current SWITSA can be referenced at the following website: http://www.kimleyhorn.com/projects/caarchitecture/project_reports.htm.

INTRODUCTION TO ROUTES OF SIGNIFICANCE Routes of significance (RoS) are metropolitan area, non-Interstate highways designated by states that merit the collecting, monitoring, and reporting of information related to traffic and travel conditions in collaboration with local or regional agencies. Factors that were considered in designating RoS included roadway safety (e.g., crash rate, routes affected by environmental events), public safety (e.g., evacuation routes), economic productivity, severity and frequency of congestion, and utility of the highway to serve as a diversion route for congested routes. RoS consist of State highways and local principal arterials. Appendix E shows a statewide listing of RoS by district, county, route, direction, postmile start, segment description, and postmile end. Caltrans’ state-owned routes serve as vital RoS for metropolitan regions and communities. For the purpose of this report, state routes were identified as RoS that merit the collection, monitoring, and reporting of activities as specified in federal regulations. Caltrans has approximately 4,837 RoS lane miles in the RTSMIP.

• Sacramento Region: 213 RoS lane miles

• San Francisco Region: 548 RoS lane miles

• San Jose Region: 59 RoS lane miles

• Los Angeles Region: 3,223 RoS lane miles

• Riverside Region: 426 RoS lane miles

• San Diego Region: 368 RoS lane miles Local principal arterials also serve as vital routes for local regions and communities, but have not been identified as RoS at this time. Economic vitality, goods movement, and enhancing quality of life are all factors to consider in designating RoS for a local region and community. Many of the principal arterials in local jurisdictions do not meet all of the provisions in the regulations to support the critical functions of RoS, including collection, monitoring, and reporting capabilities. Appendices L through Q are reserved for future local principal arterial RoS.

Caltrans evaluated all proposed state-owned RoS for inclusion in the RTSMIP. Caltrans based the evaluation on the factors in the federal regulations, the criteria Caltrans established for RoS, and the proficiency of the route to comply with the four reporting provisions. Caltrans used the LCS compliance data to ensure state-owned RoS attained 85 percent accuracy or higher for permits, construction, and maintenance closure activities. The extensive breadth of this data in the LCS includes every state-owned route in its entirety throughout California. All state-designated RoS have a CMS displaying travel time information during peak commute hours as motorists enter into a metropolitan area, demonstrating compliance with travel time information. Throughout the process of designating RoS, Caltrans collaborated with regional transportation partners by facilitating focus group meetings, specifically targeting the process and technical strategies. Caltrans provided criteria and guidance documents to assist in understanding how to select RoS and the process involved in submitting the routes, along with supporting compliance documentation addressing the four traffic and travel reporting conditions. Caltrans also provided each regional transportation partner with a letter of participation memorializing the collaborative efforts. Appendix R provides an example of the collaboration documents with regional transportation partners as required by federal regulations.

1. CONSTRUCTION ACTIVITIES (STATE ROUTES OF SIGNIFICANCE)

Federal regulations require state DOTs to provide traffic and travel conditions through the RTSMIP. The timeliness for the availability of information regarding full construction activities that close or reopen roadways or lanes will be 10 minutes or less from the time of the closure or reopening within metropolitan areas. Intermittent or short-term lane closures of limited duration that are less than the required reporting times are not regulated for compliance in this provision. Caltrans uses two tools to report, monitor, and status construction activities on state-owned RoS. The first tool is the Lane Closure System (LCS), an Oracle database that contains all information related to planned lane closures for all 12 Caltrans districts. The second tool is QuickMap, a web page that is updated every five minutes with real-time traffic information feeds from various data sources, including: Caltrans’ Commercial Wholesale Web Portal (CWWP), Changeable Message Signs (CMS) content, the Caltrans Highway Information Network (CHIN), the Transportation Management Center Activity Log (TMCAL), and the LCS. Caltrans uses QuickMap to make real-time traveler information available to motorists. Caltrans demonstrates compliance with construction activity regulations by reporting all planned lane closures on State highways to the Transportation Management Center (TMC) before the first advanced warning sign is placed on the roadway. This process is referred to as “10-97.” When the TMC staff member is notified and inputs “10-97” into the LCS, a traffic device icon appears in QuickMap with estimated end times and dates for the planned closure. At the end of the planned closure, the TMC is notified after all of the advanced warning signs are removed from the roadway. This process is referred to as “10-98.” When “10-97” and “10-98” are reported to the TMC within the specified end times and dates, the lane closure is considered “accurately statused.” If either a “10-97” or a “10-98” occurs without the reciprocating activity, this is considered “not accurately statused.” For construction activity compliance, Appendices G-K provide compliance reports for statewide planned lane closures on state-owned RoS for a three-month period from January through March 2015. For planned closures, approval must be obtained from the District Traffic Manager (DTM) one week before the closure takes place. Once approved, the closure is posted in the LCS and becomes active before the first advanced warning sign is placed on the roadway. The lane closure is considered complete after all of the advanced warning signs are removed from the roadway. Emergency closures do not require DTM approval and are entered into the LCS immediately upon notification by the TMC staff member.


21

Caltrans uses QuickMap, the LCS and CMS to disseminate real-time system information as follows:

• QuickMap is a web-based map which displays current traffic speeds, roadway incidents, full closures, lane closures related to construction, active CMS, CCTV (Closed Circuit Television) camera images, and chain controls. The Headquarters (HQ) Traveler Information Coordinator and the Public Information Officer (PIO) manage the information shown on QuickMap.

• The LCS is an Oracle database which contains start and end times related to planned lane

closures for all 12 districts. The Statewide Lane Closure Management Coordinator manages LCS.

• CMS may be used to inform travelers about active construction activities on highways.

The LCS disseminates construction information to QuickMap, the CWWP, the Performance Measurement System (PeMS), and the CHIN. The lane closure data files in QuickMap and the CWWP are updated every five minutes. In terms of accuracy, the LCS is up and running approximately 99 percent of the time (excluding a daily 15 minute routine maintenance period). The real-time information availability for lane closures from all districts exceeds the 90 percent threshold. Of the 12 Districts, the TMCs in District 1, 2, 5, and 9 do not operate 24 hours per day, 7 days per week. When these districts have a planned lane closure scheduled after business hours, the lane closure is entered into the LCS by one of the neighboring districts. For scheduled planned lane closures that occur after the TMC business hours, District 1 notifies District 4, District 2 notifies District 3, and Districts 5 and 9 notify District 6. Due to intermittent cell phone coverage in rural areas, there may be occasions where planned lane closures are not statused within the 20 minute timeframe as stated in the regulations. These occasions are rare and Caltrans is currently exploring the use of LCS mobile applications with broadband coverage allowing field personnel to status lane closures remotely.


22

2. ROADWAY OR LANE-BLOCKING INCIDENTS (STATE ROUTES OF SIGNIFICANCE)

Federal regulations require that the availability of information related to roadway or lane-blocking traffic incidents within metropolitan areas to be 10 minutes or less from the time the incident is verified. Caltrans uses the following tools to report, monitor, and status incidents on State highways: the TMCAL, the Advanced Traffic Management System (ATMS), the Intelligent Roadway Information System (IRIS), and the California Highway Patrol Computer-Aided Dispatch (CHP CAD).

• The TMCAL is a MySQL statewide database where incidents are logged and fed into QuickMap. From the time a roadway or lane-blocking incident is reported to the TMC, the latency between the incident reporting and the data entry into the TMCAL by staff is minimal and within the 85 percent accuracy threshold. After the incident is entered into the TMCAL, the process to store and disseminate the information is automated.

• The ATMS is a statewide database which uses ITS elements to gather real-time

information on State highways and distribute the information to the district TMCs.

• The IRIS is a statewide database used to monitor incidents on State highways.

• The CHP CAD is a statewide database where local dispatchers enter incident information gathered from officers in the field. The CHP CAD feeds real-time incident updates to the TMCAL, which in turn feeds the incident into QuickMap.

• The CWWP houses data and makes it available for government and local agencies, cities,

counties, and the public. Caltrans disseminates traveler information through the CHIN IVR number 1-800-427-7623 (1-800-GAS-ROAD), QuickMap, the CWWP, and CMS signs. The CHIN IVR, QuickMap, the CWWP, and the general messages for the CMS are managed by the HQ Office of Traffic Management. The accuracy and availability of roadway and lane-blocking incidents by Caltrans meets or exceeds the requirements through the TMCs that are staffed and managed 24 hours per day, 7 days per week, and through the use of an automated system which populates the TMCAL database. Incidents occurring in districts that are not continuously operational are reported to the neighboring TMCs that function 24 hours per day, 7 days per week. The TMCs also have reporting policies to local entities as appropriate and required, and also report with the neighboring TMCs when an incident affects more than one district.


23

For roadway and lane-blocking incidents, Caltrans and the CHP work together to monitor and report highway conditions. The CHP uses the CAD to track all accidents on the State Highway System (SHS). The dispatcher enters the information into the CAD as soon as it is obtained from the reporting party. Typos are generally corrected immediately after the information is entered. The Media CAD, a limited subset of the CAD determined for public consumption by the CHP, uploads the information in five minutes or less. The process is subject to human error yet is generally very accurate and meets the federal regulation’s 85 percent minimum accuracy threshold. The Media CAD is never off-line and is 100 percent reliable and available. It has back-up servers and four hubs; therefore, updates and routine maintenance are completed one hub at a time. The Media CAD meets the 90 percent availability requirement as outlined in federal regulations. The incident reporting Standard Operating Procedure (SOP) is that the CHP enters the information into the CHP CAD which is then released to the Media CAD and the CWWP. If the event is reported by a CHP field officer, it is considered verified. If it is relayed by the public via 911, there needs to be either multiple 911 calls, verification by CCTV, or field verification by the CHP or Caltrans personnel before it is considered verified. When confirmation is received that the event is no longer affecting the roadway, the incident is closed out in the CAD and the CWWP no longer shows the event. In general, the information entered by the CHP is in the CWWP before Caltrans is aware there is an incident. The latency between the CAD and the CWWP is small (approximately five minutes); therefore, the event will always be available to the public within approximately five minutes. Caltrans does not have the ability to affect “false data,” meaning data that may exist even though there is no actual event. Caltrans utilizes CCTV and/or Caltrans field personnel to verify there is no incident, or that an incident has been completed, at which point Caltrans relays the information to the CHP who in turn closes the incident, effectively removing it from the CWWP.


24

3. ROADWAY WEATHER OBSERVATIONS (STATE ROUTES OF SIGNIFICANCE)

Federal regulations require the availability of information about hazardous driving conditions and roadway or lane closures or blockages due to adverse weather conditions to be 20 minutes or less from the time the hazardous conditions, blockage, or closure is observed. Caltrans reports weather statewide using similar weather-related tools: the CHP CAD, the Road Weather Information System (RWIS), the Fog Detection and Warning System (FDWS), and Chain Controls. Once the data is gathered or reported it is entered into the CHIN. Data can be entered into the CHIN using the TMCAL or by the Headquarters Communication Center (HCC) receiving a call, facsimile, or e-mail, and manually entering the data. From the time the TMC is notified, the process is fully automated with a Mean Time Between Failure (MTBF) that meets the required accuracy.

• The RWIS consist of networks of weather monitoring stations that collect weather condition data on roadways. The system is comprised of Environmental Sensor Stations (ESS) in the field, a communication system for data transfer, and central systems to collect field data from numerous ESS. These stations measure atmospheric, pavement, and/or water level conditions.

• The FDWS consists of visibility sensors, speed detectors and cameras to detect

congestion and visibility problems that could affect driver and passenger safety on roadways. Through intelligence built into the ITS product, the system alerts motorists automatically of adverse weather conditions and slow speeds by using CMS and Highway Advisory Radio (HAR). The installation is 40 percent solar-powered, using both point-to-point and point-to-multipoint wireless radios to provide network connectivity. Local field controllers allow the field equipment to work autonomously should a break occur in communications to the central system.

Caltrans provides real-time roadway weather information on State highways through three sources: the IVR, the CWWP, and the Web. Additionally, the TMCs have reporting protocols to local entities as required. When adverse weather conditions cause lane closures, Caltrans personnel relay the information to the TMC dispatch and similarly update the TMC when the closure is removed. The TMCs and Maintenance Dispatch report incidents as identified in the Highway Conditions Reporting Matrix to the HCC within 10 minutes of notification of the incident, as well as to their district executive management. The Traffic Management Team (TMT) may also respond to a weather-related road closure, and can perform a travel run to determine delay time.


25

Inter-agency coordination between Caltrans and the CHP occurs in the event of a major storm that closes the highway. The CHP performs escorts prior to the closure and Caltrans is responsible for putting the closure in place. The incident information is reported to and received by the TMC, and a dispatcher enters the data into the TMCAL, which is disseminated to the public. The TMCs operating 24 hours per day, 7 days per week have negligible system down time, and exceed the 90 percent availability requirement (except in the case of a power outage). Caltrans districts get their weather information from similar sources and then enter this information into the CHIN. The TMC will relay the information to the HCC, and staff will then either enter the data into the TMCAL, or directly into the CHIN. All districts use weather information from the CHP CAD, Caltrans maintenance supervisors, and the National Oceanic Atmospheric Administration (NOAA) for roadway weather. Districts 1, 2, 3, 6, 8, 9, and 10 collect the RWIS weather data. Districts 2 and 3 use the TMCAL to populate the weather information to the CHIN. The other districts input the data manually into the CHIN. District 10 plans to switch to the TMCAL in the future. District 11 has a system designed to automatically post any information to the CHIN. Appendix B shows a detailed summary of roadway weather tools and observations by district, and also discusses the accuracy and availability of roadway weather real-time information. Both Caltrans and the CHP jointly decide when to close State highways due to adverse weather conditions. Either Caltrans or the CHP will initiate the discussion based upon on site visual inspection of the conditions on the facility. The closure is then reported to the TMC and the CHP dispatch. The TMC and the CHP place this information into their databases and tracking systems.


26

4. TRAVEL TIME INFORMATION (STATE ROUTES OF SIGNIFICANCE)

Federal regulations require the timeliness for the availability of travel time information along limited access roadway segments within metropolitan areas to be 10 minutes or less from the time the travel time calculation is completed. For the purposes of reporting real-time travel information, Caltrans has divided the State into five metropolitan regions: Sacramento, Bay Area (San Francisco and San Jose), Los Angeles, Riverside, and San Diego. Appendix C is a statewide graphic of the highlighted regions. Throughout the metropolitan areas of California, Caltrans utilizes CMS to provide real-time travel information on State highways. All five regions are in federal compliance and real-time travel time information is provided on all state-owned RoS in each metropolitan region. For travel time compliance, Appendix F lists all CMS statewide displaying travel time information on state-owned RoS by district, county, route, CMS location, direction, postmile start, segment description, and postmile end. The CMS are generally located within the limits of the RoS.

State Routes of Significance Travel Time Information – Sacramento Region (District 3)

• El Dorado, Placer, Sacramento, and Yolo Counties

• Cities of Sacramento, Roseville, and Arden Arcade

• The Metropolitan Planning Organization (MPO) for the Sacramento Region is the Sacramento Area Council of Governments (SACOG).

District 3 displays travel times on State highways with updates provided typically at five minute intervals. The travel times posted at CMS locations are initially verified with field staff driving the segments to ensure accuracy. Travel times are verified by driving the route using a tachometer to confirm the actual time information. A tachometer is a device used to estimate traffic speed and volume. A vehicle is equipped with a sensor and “tach runs” can be completed to record the traffic data. The TMC operator staff checks posted travel times along with the other posted CMS messages in the district. If a travel time appears unusual, the operator will check the camera and PeMS data to ascertain if there are reasons to explain the unusual posted travel time. As a fail-safe measure, if more than a three mile segment of detection is not functional, the system will stop displaying travel times and the CMS location will be blanked. Therefore, the system improves accuracy by not operating if there is not adequate detection. The availability of a CMS location for posting travel times encounters interruptions only in the following cases: incident management, construction traffic management, and emergency notifications such as America’s Missing Broadcast Emergency Response (AMBER) for missing children and Blue Alerts, which assist in the apprehension of violent criminals who kill or seriously injure law enforcement officers. Over a three-month period, CMS locations operated greater than 96 percent of the time. Non-operational CMS locations are reported timely to the Electrical Systems Branch for investigation. Once an operator notes that a CMS is blank instead of displaying travel times, the location is reported to the Electrical Support Systems Branch for investigation. Any necessary field repairs are submitted to maintenance through the Integrated Maintenance Management System (IMMS). Travel time information displayed on CMS for state-owned RoS in the Sacramento Region is illustrated in Table 7.

State Routes of Significance Travel Time Information – Bay Area Region (Districts 4 and 5)

• Alameda, Contra Costa, San Francisco, San Mateo, Marin, San Benito, and Santa Clara Counties

• Cities of San Francisco, Oakland, Hayward, San Jose, Sunnyvale, and Santa Clara

• The MPO for the Bay Area Region is the Metropolitan Transportation Commission

(MTC). District 4 uses data provided by the MPO-MTC partnership. The MTC has purchased traffic data from INRIX using Global Positioning System (GPS) probe-based traffic data. The source of the GPS data is a combination of Commercial Vehicle GPS Probe, Consumer Vehicle GPS Probe, GPS-Enabled Smartphone Probe, and Cellular Network Probe. The data is fed to the fusion engine which checks and weighs the data accuracy and procedures, and estimates travel times. The technique has been tested by the Washington State Department of Transportation and the New Jersey State Department of Transportation. New Jersey validated the data on the I-95 via a second set of Bluetooth readers. The MTC validates the travel time data via a series of floating car studies. INRIX has over three years of stored data that is normalized for seasonal traffic patterns. The ATMS travel time module for District 4 is programmed on a fixed schedule of 0500 to 2100 hours daily. If the system loses the data feed from the MTC for longer than 10 minutes, the travel time system is programmed to blank out the signs. If the data feed is unable to be restored, there is an option to use the secondary source of data from Caltrans’ traffic monitoring stations. District 5 does not have state-owned RoS that qualify for the RTSMIP at this time. Travel time information displayed on CMS for state-owned RoS in the Bay Area Region is illustrated in Table 8.

State Routes of Significance Travel Time Information – Los Angeles Region (Districts 7 and 12)

• Orange and Los Angeles Counties

• Cities of Los Angeles, Long Beach, and Anaheim

• The MPO for the Los Angeles Region is the Southern California Association of Governments (SCAG).

District 7 displays travel times on approximately 45 CMS using roadway loop detectors. A computer algorithm gathers the real-time loop information and automatically computes an estimated travel time to selected target locations. The CMS are updated every three minutes. To ensure accuracy when no detector information is available, the CMS will not display a travel time for that target location. The travel times are displayed on CMS daily from 0500 to 2100 hours. This wide range of available travel times encompasses 100 percent of the daily congestion period on roadways. The travel times are not displayed outside of this period when congestion and traffic volumes are lower. Due to insufficient detection, designated travel times may not be displayed on CMS, yet the real-time information is available above the 90 percent requirement during the operational time frame. District 12 checks the accuracy of speed which is calculated with the loop detection system, and utilizes radar guns and tach runs to verify traffic conditions. This analysis concludes that the speed calculation is 95 percent accurate. The travel times are displayed on CMS from 0600 to 2200 hours. An algorithm calculates travel time based on real-time traffic speed along a corridor. The algorithm has the intelligence to extrapolate the calculation in the event of malfunction for up to two and a half miles and is 95 percent accurate. Travel time information displayed on CMS for state-owned RoS in the Los Angeles Region is illustrated in Table 9.

State Routes of Significance Travel Time Information – Riverside Region (District 8)

• Riverside and San Bernardino Counties

• Cities of Riverside, San Bernardino, and Ontario

• The MPO for the Riverside Region is the SCAG. District 8 currently displays travel times on 35 CMS on Routes I-10, I-15, I-215, as well as other state routes between 0500 and 2000 hours. The overall PeMS detector reliability has been difficult to measure due to ongoing construction activities and wire theft which lowered the number of available detectors. Caltrans purchases third party data which is integrated into the central freeway management system; therefore, travel times are not affected by failed detection. The 85 percent accuracy is easily attained and verified through tach runs. The freeway management system has an uptime that exceeds 99 percent. The only factor that affects the availability is the status of detection. The availability will be measured through the PeMS. A log of all the messages and the times they were posted is maintained in the database. The availability of existing signs that are outside of construction zones exceeds 90 percent. The purchase of third party data will allow for travel times to be posted where detection is unavailable. Travel time information displayed on CMS for state-owned RoS in the Riverside Region is displayed in Table 10.

State Routes of Significance Travel Time Information – San Diego Region (District 11)

• San Diego County

• Cities of San Diego and Carlsbad

• The MPO for the San Diego Region is the San Diego Association of Governments (SANDAG).

District 11 achieves travel time accuracy by verifying the routes and calculated travel time as needed by driving pilot vehicles to identified destinations during various hours of the day. Once the calculated travel time and the driven travel time are within one to two minutes of each other, the destinations are displayed on CMS. The travel times are verified in lane number two at the posted or prevailing speed (if below posted speed). Travel times are displayed on commute routes Monday through Friday during commute hours: 0500-1000 and 1400-1900 hours. The travel time destination display data depends on the performance of vehicle detection stations, and the reliability of detection data is over 90 percent. Travel time information displayed on CMS for state-owned RoS in the San Diego Region is displayed in Table 11.

5. ITS ARCHITECTURE (STATE ROUTES OF SIGNIFICANCE) Federal regulations require all states and regions which have created a Regional ITS Architecture to evaluate their Regional ITS Architecture to determine whether the architecture addresses real-time highway and transit information needs, and the methods needed to meet such needs. The regulation further states that Regional ITS Architectures shall feature the components and functionality of the RTSMIP. The California Statewide ITS Architecture (SWITSA) contains a blueprint for deployment of ITS projects that fall within the category of statewide and interregional ITS services related to regional integration and cooperation among stakeholders. The SWITSA was developed in 2004, updated in 2010, and is currently undergoing an update. The update will include deployment of the ITS SystemBuilder tool, which will enable users to view the SWITSA and all other Regional ITS Architectures within the State. The SWITSA includes the following regional service packages that support the RTSMIP established in accordance with 23 CFR 511.

• MC10: Maintenance and Construction Activity Coordination supports the dissemination of maintenance and construction activity to information service providers (ISPs) who can provide the information to travelers.

• ATMS08: The Traffic Incident Management System manages both unexpected incidents

and planned events so that the impact to the transportation network and traveler safety is minimized.

• MC03: Road Weather Data Collection collects current road and weather conditions using

data collected from environmental sensors deployed on and about the roadway.

• MC06: Winter Maintenance collects current road and weather conditions using data collected from environmental sensors deployed on and about the roadway.

• ATIS1: Broadcast Traveler Information collects traffic conditions, advisories, general

public transportation, incident information, and roadway maintenance and construction information; and broadly disseminates this information through existing infrastructures.

• ATMS06: Traffic Information Dissemination provides driver information using roadway

equipment such as CMS or HAR. The user service packages referenced above represent a subset of a more comprehensive list contained within the SWITSA. The current SWITSA can be referenced at the following website: http://www.kimleyhorn.com/projects/caarchitecture/project_reports.htm.


33

CONCLUSION The RTSMIP provides traffic and travel condition information on Interstate highways and state-owned RoS as required by the FHWA. This traveler information can be used by public agencies, other public and private parties who deliver value-added information products and services, and the traveling public. The data exchange formats allow information to be more easily interchanged and used among government agencies and other parties. Caltrans has demonstrated compliance with 23 CFR 511. Caltrans operates a statewide incident reporting system which facilitates the real-time electronic reporting of surface transportation incidents to a central location for use in monitoring an event, providing accurate traveler information, and responding to incidents as appropriate on Interstate highways and state-owned RoS. Through the use of multiple sources, tools, processes, systems, and databases, Caltrans has also established conformance with real-time travel information reporting in reference to the four main provisions of the regulation addressing: construction activities, roadway or lane-blocking incidents, roadway weather observations, and travel time information. Local, statewide, and regional data substantiates Caltrans’ adherence to the regulations while also verifying real-time information accuracy of 85 percent accurate, and information availability of 90 percent.

The ITS Architecture developed by Caltrans is compliant with the regulations and addresses real-time highway and transit information needs, and the concurrent methods to meet such needs. The SWITSA demonstrates a comprehensive set of regional service packages including MC10, ATMS08, MC03, MC06, ATIS1, and ATMS06, featuring the components and functionality of the RTSMIP as required by 23 CFR 511. The SWITSA contains a blueprint for deployment of ITS projects related to regional integration and cooperation among stakeholders. The SWITSA was developed in 2004, updated in 2010, and is currently undergoing an update to address ongoing needs of ITS coverage, monitoring systems, data fusion and archiving, and highway and transit information accessibility for other states as federally required. The update will include deployment of the ITS SystemBuilder tool which will enable users to view the SWITSA and all other Regional ITS Architectures within the State via a website.

APPENDIX B: SUMMARY OF ROADWAY WEATHER OBSERVATIONS

TOOL DISTRICT PROCESS AVAILABILITY ACCURACY California Highway Patrol Computer- Aided Dispatch (CHP CAD)/ Media Computer- Aided Dispatch (Media CAD)

All

CHP field personnel or 911 calls to alert the CHP Communication Center. Information is relayed related to high winds, fog, dust, snow, flooding, rock and mud slides, wild fire, and other adverse weather or natural disaster conditions that affect the highway system. The information is placed into CHP CAD which is then released to Media CAD. If the event is reported by a CHP field officer, it is considered verified. If it is relayed by the public via 911, there needs to be either multiple 911 calls, verification by CCTV, or field verification by the CHP or Caltrans’ personnel before it is considered verified. Once the event is confirmed as no longer affecting the roadway, it is closed out in CAD and the event is no longer shown. The CHP CAD is not broadcast by Caltrans.

The CHP CAD has quadruple servers and the CAD information is available to the CWWP 100 percent of the time.

Field personnel, CCTV, RWIS, FDWS, or multiple 911 calls are utilized to verify that an event is occurring. Caltrans will not be aware of the end of an event until field personnel verify and the event is closed by CHP (CAD) or Caltrans (CHIN).

Road Weather Information System (RWIS)

1, 2, 3, 6, 8, 9 and 10

RWIS feeds information back to the server in HQ and displays data via website of the conditions at the individual locations. For some districts, this information is also sent to the National Weather Service (NWS) in Hanford, California, where the data is incorporated into their forecasting models. Caltrans has a project started to include both RWIS and MesoWest weather data to QuickMap.

Maintenance issues with RWIS are ongoing but can be reconciled by the NWS. The NWS has a large volume of data to compare what is being or not being reported from our system.

The RWIS location data is “point” data, meaning it is not relied upon as a regional weather predictor. The TMC looks at the aggregation of data provided by the NWS in Hanford, California, including Caltrans' RWIS data.

TOOL DISTRICT PROCESS AVAILABILITY ACCURACY Caltrans Highway Information Network (CHIN)

All

Information is received in the TMC via the CHP and Media CAD, both of which are present in the TMC along with State forces (e.g., Maintenance, Storm Patrol), weather service providers, Google Maps, and traditional network Media-TV news, etc. Upon confirmation of major weather events affecting the highway system, the TMC enters the information into logging systems and also notifies the HCC. The HCC then enters the data into CHINs UNIX-based system to support the 1-800 Service (IVR), and the logging systems update CWWP.

All processes are automated; the reliability is based on the uptime of the associated components.

All accuracy is based on the field sensor.

Chain Control Reporting

1, 2, 3, 4, 6, 7, 8, 9, 10 and 11

Districts notify the HCC of Chain Control requirements which update the 1-800 Service (IVR), CWWP, and QuickMap. The majority of districts enter chain control requirements into TMCAL as well.

Availability is based on component uptime as the system is automated from the time of entry to notification.

Information is accurate and comes from knowledgeable field personnel.

Fog Detection and Warning System (FDWS)

6 and 10

FDWS is used by D6 and D10, and the system automatically sends a message to the CMS when it detects fog. CMS messaging is then picked up by the Satellite Operations Center Control System (SOCCS) and fed to CWWP.

Since the system is automated, the reliability is dependent on the uptime of each component; the components are monitored and have rollover functionality.

The accuracy is based on the inaccuracy of the sensor itself.
