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.

Benefits

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.
