  1. Handheld Computing Devices for Mobile Traffic Records Management Allen Parrish David Brown CARE Research & Development Laboratory The University of Alabama Tuscaloosa, AL Mike Carroll Alabama Administrative Office of Courts Montgomery, AL

  2. CARE Research & Development Laboratory • Organization of approximately 20 people (eight full-time) • Includes faculty, professional staff (SW developers, engineers), and students • Housed within Computer Science at the University of Alabama • Current sponsors: • National Highway Traffic Safety Administration • Federal Motor Carriers Safety Administration • State of Alabama, Departments of: • Transportation • Economic and Community Affairs (GR-TSO) • Administrative Office of Courts • North Carolina, Tennessee, Delaware, and Iowa • Southwest AL Integrated Criminal Justice System

  3. Our Projects • CARE is our primary product • Critical Analysis Reporting Environment • Supports the analysis of crash data • Produce planning documents, reports and studies • Alabama Crash Facts Book (since 1998) • Alabama and North Carolina Highway Safety Plans • Special studies (http://care.cs.ua.edu) • Work with general law enforcement information systems • Crash Form Entry System • E-Citation System • Law Enforcement Tactical System (LETS) • Model Integrated Defendant Access System (MIDAS)

  4. Application Overview • CARE: Critical Analysis Reporting Environment • Crash Form Entry System • E-Citation • LETS: Law Enforcement Tactical System • MIDAS: Model Integrated Defendant Analysis System

  5. CARE: Critical Analysis Reporting Environment • Saving lives since 1982…. • Historical summary: • CARE: Originally a front end to SPSS • Evolved to a separate Windows-based product • Basic analysis functionality also over the Web • Location analysis and roadway geometrics • Won NHTSA Administrator’s award in 1995 • Current or past contracts with eight states: • AL, DE, IA, FL, MI, NC, TN • Negotiations ongoing with 2-3 other states

  6. CARE Software • Allows access to crash data • Several analysis techniques: • Frequency distributions • Cross-tabulations • Crash rates per population size (ACT) • Location analysis (variety of techniques here) • Information Mining (IMPACT)

  7. Crash Form Entry System • Supports automated data entry onto a crash form from an in-car laptop • Includes support for drawing collision diagrams (Easy Street Draw) • Also fully functional on a tablet PC • Some data can also be entered via a PDA • Wireless communication from PDA to the laptop • PDA contains a built-in scanner for scanning driver’s license bar codes

  8. E-Citation System • Citation data may be entered via: • Laptop • Tablet • PDA and transmitted to the laptop over a wireless network • Project: E-citation for commercial truck enforcement in Alabama (MCSAP) • Funded by FMCSA • Status: Pilot was initiated at the Heflin Weigh Station in January • Full rollout to the entire MCSAP unit scheduled by mid-2004

  9. LETS: Law Enforcement Tactical System • Web-based system • Integrates 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 individual • Deployed in January 2003 • Lots of early success stories • Approximately 4000 registered users in AL.

  10. LETS (continued) • Databases are being added regularly • Pardons and Paroles • Court Cases • Prison Census • Death Certificates • SmartCOP data • Jefferson County mugshots • Longer term issues: • User interface improvement • Mobilization • Fuzzy searches • Virtual lineups • Integration among other states’ data

  11. MIDAS: Model Integrated Defendant Access System • Funded by NHTSA to track impaired drivers • Web-based system • DUI arrests are routed through the court referral (CRO) system • MIDAS provides a statewide system for CROs to use: • Recording and accessing case history information • Information available for statewide sharing

  12. Wireless Projects • Designed to migrate our non-wireless apps to a mobile environment: • WLAN extensions to crash entry and E-citation systems • Wide area mobile E-citation • Voice-based crash entry and E-citation • Mobile LETS • Also for infrastructure support: • Mobile data capture devices • Wide Area Data Communications

  13. WLAN ACES and E-Citation • Crash form entry and E-citation: Base systems operate on laptops • Need to be able to walk around and capture data • Current system: • Supports “satellite” PDAs • Master application runs on laptop in the car

  14. Wireless transmission of the datafrom PDAs to laptop • Capability of simultaneous data entry

  15. Report built on laptop Data capture Data capture Data capture Basic WLAN Architecture

  16. Wide Area Mobile E-Citation • Phase 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. issues • Our strategy: • Communication-independent architecture • We support: • Dial-up • Cellular • 802.11 • Wired LAN connection

  17. Voice-Based Crash Entry and E-Citation • Prototype project with Auburn Center for IMPACT • Presentation forthcoming in this session

  18. Voice/Mobile LETS • Need to make LETS more useful in a mobile officer setting • Issues: • Streamlining interface to reduce bandwidth and information overload • Dealing with intermittent or no mobile connectivity • Two separate efforts underway: • Voice LETS (voice recognition) • Mobile LETS (streamlined interface and/or local data)

  19. Voice LETS • Another joint effort with Auburn IMPACT center • Basic idea: • Speak input information • Receive output information via voice or in silent mode to data screen • Really a LETS subset to look up a specific individual: • Speak SSN, license ID, tag #, name/DOB • Physical description of individual or vehicle read back

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

  21. Voice LETS

  22. Mobile LETS • Conducting feasibility study right now • Two 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 issues • Will likely lead to two separate products: • LETS GO: Laptop-based with local data and some kind of update paradigm • LETS Lite: Streamlined interface for ubiquitous computing devices

  23. Mobile Data Capture • Would 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

  24. Tablet PCs • Currently 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.com • May be useful to build a sleeve for this device to hold various peripherals to support: • Voice input (on-board) • Bar code scanning • Electronic signatures • Video camera • GPS

  25. Possible Integrated Device Design • Added functionality (peripherals): • Bar code scanner • Mag stripe scanner • Camera • GPS • Peripheral – Oqo unit connections options include: • Building a sleeve for the Oqo and embed peripherals • Removing the processor and contents from the current Oqo box and build a new physical box for the product • Communications: • Cellular PCMCIA card • Connected cell phone • Bluetooth to a separate cell phone

  26. Wide Area Data Communications Support • Support to keep mobile law enforcement connected. • Currently experimenting with several possibilities: • Cellular • Wi-fi • We 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 enforcement • This network can ultimately be shared between law enforcement and researchers exploring wireless issues • Looking to combine with other efforts to provide statewide and regionwide coverage

  27. Summary: CRDL Activities • Basic LE and traffic safety applications: • CARE, LETS, MIDAS, crash reporting, E-Citation • Wireless projects: • WLAN extensions to ACES and E-citation • Wide area mobile E-citation • Voice-based forms entry (with Auburn) • Mobile LETS (with Auburn) • Mobile data capture devices • Wide Area Data Communications
