This report summarized the results of several ITS evaluation projects in the city of San Antonio, Texas. San Antonio had a relatively extensive implementation of ITS prior to this study and, consequently, the incremental benefits experienced in San Antonio through expansion and additions to the existing system may be somewhat smaller than the benefits that could be achieved in areas with little prior implementation of ITS.
Improvements to elements of San Antonio’s traveler information system included improvements to an Internet Web site. The Web site provided freeway traffic information including incident locations, and links to transit schedule and fare information. Modeling results indicated that travelers who use the Web site prior to traveling along a particular corridor could reduce their travel delay by 5.4 percent.
