The TransGuide system, Texas Department of Transportation's Advanced Traffic Management System in San Antonio, Texas was selected by the United States Federal Highway Administration to serve as a showcase for Intelligent Transportation Systems (ITS) under the Model Deployment Initiative program. The Automated Vehicle Identification (AVI) project of the TransGuide Model Deployment Initiative was designed to measure the traffic conditions along selected roadways within the San Antonio area by determining travel times between selected locations. This travel time data is more comprehensive than traditional point speed data because it accounts for traffic delays between points that cannot be measured by point speed detection mechanisms. The AVI system consists of 53 toll-tag sensor locations and 78,000 vehicle probe tags. The data collected by the AVI system is made available to the TransGuide system through the TransGuide Data Server.
