Houston TranStar AVI Traffic Monitoring System
AVI Technology |
How It Works
The Houston TranStar Automatic Vehicle
Identification (AVI) traffic monitoring system is used to collect real-time information
showing current travel conditions on Houston area freeways and high occupancy vehicle (HOV) lanes. This information
is provided to personnel within the Houston TranStar Center for use in detecting
freeway congestion. This travel information is also provided to the public through
media reports, displays on selected roadside electronic message signs, and on the
Houston TranStar Web Site.
A Note About Privacy
The toll tag IDs read by the system are strictly used for estimating average travel times and are not used to "track" individual tags. Each tag ID is anonymized upon receipt and no personal information is stored by the system.
