  2. Presentation Overview • How we got here • Application testing and results • Deployments and alternatives • Upcoming applications

  3. Houston Experience • Desire for expansion of existing travel time map • Exploration of more cost effective alternatives (AVI equip +$50k per site) • Demonstration of address matching technologies • Assessment of feasibility • Field deployments for arterial networks

  4. Existing TranStar Website • Award winning website experiences over 10 million page accesses/500,000 users per month on average • Freeway travel times are very well received by the public • Display of arterial travel times are desired by the public • Existing AVI technology may not be cost effective for wide area deployment on arterials

  5. Existing Technologies TranStar system currently utilizes a combination of RFID (Transcore) and radar (Wavetronix) for travel time and speed information (over 450 combined)

  6. Why try anything else? • Cost • Bluetooth peripherals are becoming widespread • Easier, non-intrusive field installation and maintenance

  7. AWAM Concept

  8. Sample Antenna Coverage

  9. Ohio DOT Demo - Dayton

  10. Arlington Virginia Demo

  11. AWAM vs Toll Tags To benchmark performance, The Bluetooth-based AWAM system was installed alongside a probe-based toll tag (AVI) system. In this recent comparison, AWAM is collecting more data samples than the alternative technology. This effort repeated a previous examination where, the AWAM samples were ~ 85% of the AVI matches. Thus illustrating that the apparent number of Bluetooth enabled devices (in discoverable mode) are actually increasing, not decreasing.

  12. IH-45 Deployment - Individual Matches with a rural incident impact on a 13 mile segment

  13. West Houston Deployment Example Arterial Data (3 traffic signals between readers) Vehicles traveling within the Progression Band Vehicles which did not travel within Progression Band

  14. Benefits • Low cost, standards-based, non-proprietary equipment and protocols. • Easy, non-intrusive field installation and maintenance. • Large penetration of field devices and data samples. • Real-time summary calculations. • Complete ownership of data by operating agency.

  15.
