CONTINUING INVESTIGATION OF ANONYMOUS WIRELESS ADDRESS MATCHING (AWAM) FOR TRAVEL TIME DATA COLLECTION Darryl Puckett and Mike Vickich Houston, Texas ITS World Congress Orlando, Florida October 19, 2011

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

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

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

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

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

AWAM Concept

Sample Antenna Coverage

Ohio DOT Demo - Dayton

Arlington Virginia Demo

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. 11

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

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

University Transportation Center for Mobility (UTCM) Funding was obtained for experimentation to test field hardened components and antenna configurations Once identified, those components were deployed for further data comparisons Deployments have been accomplished with the cooperation of City of Houston and TxDOT

UTCM Field Deployments Total of 16 sites City of Houston – 10 TxDOT – 6 Traffax – 2

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.

Based on our experience with AVI a new Bluetooth read & process method was desired to increase efficiency and accuracy Asynchronous I/O – the AWAM Advantage –As soon as a MAC address is read it is uniquely sent for processing and time stamped (or stored locally) –Enables more MAC address reads –Enables for more MAC address matches Field Software Enhancements –Duplicates can be identified and handled locally before sending back to host –Reduces bandwidth requirements (critical for cellular data transmission methods, particularly when paired with other ITS elements)
