Presentation overview
Presentation Overview

  • How we got here

  • Application testing and results

  • Deployments and alternatives

  • Upcoming applications

Houston experience
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
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
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
Why try anything else?

  • Cost

  • Bluetooth peripherals are becoming widespread

  • Easier, non-intrusive field installation and maintenance

Awam vs toll tags
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.

Example Arterial Data (3 traffic signals between readers)

Vehicles traveling within the Progression Band

Vehicles which did not travel within Progression Band


  • 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.
