Summary Information

In San Antonio, Texas, an integrated freeway/incident management system was developed as part of a freeway expansion project. The project covered a 28.9-mile stretch of I-10, I-410, and US 281 in the northern region of San Antonio. The cost of the freeway and incident management expansion project was approximately $26.6 million with an estimated annual O&M cost of $852,000. The majority of the cost was for surveillance, detection, and information equipment and communications hardware. Detection technologies such as acoustic sensors, loops, and digital detectors, closed circuit television (CCTV) cameras, dynamic message signs and lane control systems, and supporting fiber optic communications infrastructure were deployed. The cost of mobilization (e.g., keeping traffic moving during deployment) during the expansion was approximately $2 million. This cost was kept low based on the planning decision to deploy the ITS components as part of the highway reconstruction.

Costs From This Source

An advanced highway-rail intersection warning system was deployed for just over $350,000 as part of the San Antonio Metropolitan Model Deployment Initiative.

In-vehicle navigation units and real-time traveler information software development were the main cost drivers for the San Antonio TransGuide MMDI project to improve operations at several public agencies.

Over half of the $3.25 million cost for the San Antonio Lifelink advanced telemedicine project was attributed to reseach and development.

The integrated freeway/incident management system covering 28.9 miles in San Antonio was deployed for approximately $26.6 million.

Benefits From This Source

Evaluation indicated that integrating DMS and incident management systems could reduce crashes by 2.8 percent, and that integrating DMS and arterial traffic control systems could decrease crashes by 2 percent, in San Antonio, Texas.

Evaluation of freeway DMS integrated with incident management in San Antonio, Texas, found fuel consumption reduced by 1.2 percent; integrating the DMS with arterial traffic control systems could save 1.4 percent.

In San Antonio, Texas, 60 percent of drivers of transit vehicles equipped with in-vehicle navigation devices reported that they saved time and felt safer.
