  • Handheld Computing Devices for Mobile Traffic Records ManagementAllen ParrishDavid BrownCARE Research & Development LaboratoryThe University of AlabamaTuscaloosa, AL

    Mike CarrollAlabama Administrative Office of CourtsMontgomery, AL

  • CARE Research & Development LaboratoryOrganization of approximately 20 people (eight full-time)Includes faculty, professional staff (SW developers, engineers), and studentsHoused within Computer Science at the University of AlabamaCurrent sponsors:National Highway Traffic Safety AdministrationFederal Motor Carriers Safety AdministrationState of Alabama, Departments of:TransportationEconomic and Community Affairs (GR-TSO)Administrative Office of CourtsNorth Carolina, Tennessee, Delaware, and Iowa Southwest AL Integrated Criminal Justice System

  • Our ProjectsCARE is our primary product Critical Analysis Reporting EnvironmentSupports the analysis of crash dataProduce planning documents, reports and studiesAlabama Crash Facts Book (since 1998)Alabama and North Carolina Highway Safety PlansSpecial studies (http://care.cs.ua.edu)Work with general law enforcement information systemsCrash Form Entry System E-Citation System Law Enforcement Tactical System (LETS)Model Integrated Defendant Access System (MIDAS)

  • Application OverviewCARE: Critical Analysis Reporting EnvironmentCrash Form Entry SystemE-CitationLETS: Law Enforcement Tactical SystemMIDAS: Model Integrated Defendant Analysis System

  • CARE: Critical Analysis Reporting EnvironmentSaving lives since 1982.Historical summary:CARE: Originally a front end to SPSSEvolved to a separate Windows-based productBasic analysis functionality also over the WebLocation analysis and roadway geometrics Won NHTSA Administrators award in 1995Current or past contracts with eight states:AL, DE, IA, FL, MI, NC, TNNegotiations ongoing with 2-3 other states

  • CARE SoftwareAllows access to crash dataSeveral analysis techniques:Frequency distributionsCross-tabulationsCrash rates per population size (ACT)Location analysis (variety of techniques here)Information Mining (IMPACT)

  • Crash Form Entry SystemSupports automated data entry onto a crash form from an in-car laptopIncludes support for drawing collision diagrams (Easy Street Draw)Also fully functional on a tablet PCSome data can also be entered via a PDAWireless communication from PDA to the laptopPDA contains a built-in scanner for scanning drivers license bar codes

  • E-Citation SystemCitation data may be entered via:LaptopTabletPDA and transmitted to the laptop over a wireless networkProject: E-citation for commercial truck enforcement in Alabama (MCSAP)Funded by FMCSAStatus: Pilot was initiated at the Heflin Weigh Station in JanuaryFull rollout to the entire MCSAP unit scheduled by mid-2004

  • LETS: Law Enforcement Tactical SystemWeb-based systemIntegrates a number of state databases (driver license, driver history, warrants, etc.)Allows the look-up of an individual by name, characteristics, etc.Returns personal information about the individualDeployed in January 2003Lots of early success storiesApproximately 4000 registered users in AL.

  • LETS (continued)Databases are being added regularlyPardons and ParolesCourt CasesPrison CensusDeath CertificatesSmartCOP dataJefferson County mugshotsLonger term issues:User interface improvementMobilizationFuzzy searchesVirtual lineupsIntegration among other states data

  • MIDAS: Model Integrated Defendant Access SystemFunded by NHTSA to track impaired driversWeb-based systemDUI arrests are routed through the court referral (CRO) systemMIDAS provides a statewide system for CROs to use:Recording and accessing case history informationInformation available for statewide sharing

  • Wireless ProjectsDesigned to migrate our non-wireless apps to a mobile environment:WLAN extensions to crash entry and E-citation systemsWide area mobile E-citationVoice-based crash entry and E-citationMobile LETSAlso for infrastructure support:Mobile data capture devicesWide Area Data Communications

  • WLAN ACES and E-CitationCrash form entry and E-citation: Base systems operate on laptopsNeed to be able to walk around and capture dataCurrent system:Supports satellite PDAsMaster application runs on laptop in the car

  • Wireless transmission of the datafrom PDAs to laptopCapability of simultaneous data entry

  • Basic WLAN Architecture

  • Wide Area Mobile E-CitationPhase II of E-citation project:Currently deployed at weigh station (fixed location)Must now deploy in cars (mobile setting)Must deal with mobile data comm. issuesOur strategy:Communication-independent architectureWe support:Dial-upCellular802.11Wired LAN connection

  • Voice-Based Crash Entry and E-CitationPrototype project with Auburn Center for IMPACTPresentation forthcoming in this session

  • Voice/Mobile LETSNeed to make LETS more useful in a mobile officer settingIssues:Streamlining interface to reduce bandwidth and information overloadDealing with intermittent or no mobile connectivityTwo separate efforts underway:Voice LETS (voice recognition)Mobile LETS (streamlined interface and/or local data)

  • Voice LETSAnother joint effort with Auburn IMPACT centerBasic idea: Speak input informationReceive output information via voice or in silent mode to data screenReally a LETS subset to look up a specific individual:Speak SSN, license ID, tag #, name/DOBPhysical description of individual or vehicle read back

  • Voice LETS PlatformsPhone (cellular or land line)Computer (using Voice over IP to connect to server)Radiophone (in experimental stages)Prototypes exist of all three platformsCurrent emphasis:Scaling phone prototype to statewide production system

  • Voice LETS

  • Mobile LETSConducting feasibility study right nowTwo emphasis areas:Streamlined user interfaces using a variety of ubiquitous computing devices (e.g., cell phone screens)Off-loaded data onto local laptop or tablet PC to deal with limited connectivity issuesWill likely lead to two separate products:LETS GO: Laptop-based with local data and some kind of update paradigmLETS Lite: Streamlined interface for ubiquitous computing devices

  • Mobile Data CaptureWould like to be able to work with small handheld devices.PDAs had both programming and performance problems.Our goal in this area: Obtain a small handheld device suitable for this mission, with acceptable performance.Based on the Microsoft Tablet PC

  • Tablet PCsCurrently working with some of the larger tablet PCs.Would like to migrate to a small PDA-sized tablet as they become available.Oqo: http://www.oqo.comMay be useful to build a sleeve for this device to hold various peripherals to support:Voice input (on-board)Bar code scanningElectronic signaturesVideo cameraGPS

  • Possible Integrated Device DesignAdded functionality (peripherals):Bar code scannerMag stripe scannerCameraGPSPeripheral Oqo unit connections options include:Building a sleeve for the Oqo and embed peripheralsRemoving the processor and contents from the current Oqo box and build a new physical box for the productCommunications:Cellular PCMCIA cardConnected cell phoneBluetooth to a separate cell phone

  • Wide Area Data Communications SupportSupport to keep mobile law enforcement connected.Currently experimenting with several possibilities:CellularWi-fiWe are comparing these two (and other) technologies:Plans to develop a community-based wi-fi network in one or more Alabama cities for use by law enforcementThis network can ultimately be shared between law enforcement and researchers exploring wireless issuesLooking to combine with other efforts to provide statewide and regionwide coverage

  • Summary: CRDL ActivitiesBasic LE and traffic safety applications:CARE, LETS, MIDAS, crash reporting, E-CitationWireless projects:WLAN extensions to ACES and E-citationWide area mobile E-citationVoice-based forms entry (with Auburn)Mobile LETS (with Auburn)Mobile data capture devicesWide Area Data Communications
