The Big Picture – Work Zone Data Management Efforts

Work Zone Activity Data (WZAD)

Digital data on when, where, and how work

zones are deployed

FHWA’s Work Zone Data Initiative (WZDI) USDOT’s Work Zone Data Exchange (WZDx)

Creating a framework for agencies to utilize

a consistent language for communicating

WZAD across jurisdictional boundaries

Creating a basic work zone data specification

to jump-staring voluntary adoption by data

producers and users across the country

Why implement WZDI/WZDx in Colorado?

• Minimize mobility and safety impacts to drivers

• Coordinate oversize/overweight vehicle permits

• Monitor work zone contractor compliance

• Track field modifications to project plans

• Track availability of ITS assets

• Gather accurate, verified data for real-time traveler information applications

• Gather and use better performance measures

• Improve dispatching and enforcement practices

6

Simply put…

Reduce burden

on labor and

associated costs

Improve work

zone outcomes

Tools for Enhancing Work Zone Data Management

Work Zone Data System (WZDS) Framework

• Helps understand how to communicate and use WZAD

effectively

• Presents concepts for structuring WZAD and WZDS to support

needs

• Includes info on collecting, storing, disseminating, managing,

maintaining, and archiving data over the WZ life cycle.

• Provides “menu of resources” to pick from to create WZDS

WZAD Data Dictionary

• Specifies consistent data with respect to meaning and

enumerated values

• Serves as a backlog of data elements to add to the WZDx

specification over time

Work Zone Data Processes in

Colorado Today

Key Considerations and Uses

• Data Collection

• Types of data collected? How? Where?

• Who collects data?

• Data Analysis

• Data applications?

• Who conducts data analysis?

• Data Reporting and Use

• Who reports on the data?

• Data updates? By whom?

• Data users? Purpose?

11

• Technologies

• Technologies used for…

• Data collection?

• Data analysis?

• Data reporting?

• Gaps and Opportunities

• Major gaps in data management?

• Information you’d like to have?

Data Collection and Analysis

12

• Sources:

• Colorado DOT

• Colorado State Patrol

• Local Entities

• Private Parties

• Variety of data is collected and posted in

multiple locations

• Work zone data focused on planned

activities (do not have active or post-

construction data)

Source Type

Traffic counters/loops Traffic Volumes

Lane/road closure reports Construction, Maintenance

Police reports Incidents, Accidents

Cell Phones GPS/Location

Toll Tags Speed, Toll Violations

Traffic Signals Signal Timing, Signal Outages

Ramp Meters Speed

Weigh-in-Motion Vehicle Weight

Manual Entry Forms (MHT,

Lane Closure)

Multiple

Salesforce Multiple

Technology and Applications

• Salesforce

• Data comes from public relations office (Salesforce -> PR Dept -> COTrip)

• COTrip

• Includes all planned activities, examples include:

• Construction engineer submits planned lane closures 1-week prior to event

• Includes information on planned work location (e.g., milepost x to y)

• Cannot make updates to planned activities

• Manual entry (submission via email, forms)

• Must provide information for each event (e.g., lane closure, reduced speed limit)

13

Coordination and Compliance

• Work Zone Project Coordination

• Coordination occurs for larger, higher visibility projects (smaller projects may have financial constraints)

• Regional project status meetings

• Bi-weekly or monthly

• Informal, information noted via spreadsheet

• Permitting

• Entities (e.g., locals, utilities) must submit a manual permit request at the regional level

• Robust system for permitting is not tied to work zone data systems

• Compliance

• Regions develop their own policies for compliance

• Construction Engineer/Inspector in charge of documenting and assessing penalties

14

Enforcement

• Larger projects include coordination with local law enforcement

• Smaller projects, coordination done on case-by-case basis

• Plans/forms must include need for law enforcement to direct traffic

• All forms are sent to Colorado State Patrol

• Speeding – double fine law is active all the time (not just when workers are present)

15

CODOT WZAD State of the Practice

• “Handful” of smart work zones are being piloted

• Building blocks in place, but WZAD is emerging concept within DOT

• CODOT recently went through restructuring

• Executive level buy-in

• Working on operational/tactical buy-in

16

Gaps and Opportunities

Need for…

• Standard data management practices around collection and storage

• Better understanding of data gathered and its use across CODOT

• Institutionalization and use of Salesforce across the state

• Better understanding of the cost of infrastructure for data collection

• One data repository for easy data extraction and sharing

• Getting (as close to) real-time work zone activity data as possible to input into TOC

• Broadening end users (post to Google, Waze, etc. – not just COTrip)

• Inclusion of incident management team

• Ability to make updates to planned activities in COTrip

• Improved coordination between maintenance and construction groups

Review of Actions

• Actions are concrete steps an agency can take –action oriented, not too prescriptive or generic

• Not all actions need to be implemented now –can prioritize actions as part of planning efforts
