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.
The evaluation report contained benefits information regarding the implementation of dynamic message signs (DMS) along a freeway corridor. Overall, focus group studies indicated that customers were satisfied with the DMS system. Focus group participants felt the DMS was reliable when proximal to the congestion or incident.
