Summary Information

As part of the San Antonio TransGuide Metropolitan Model Deployment Initiative (MMDI) program, in-vehicle navigation (IVN) units were deployed to enhance traveler information systems and improve operations at several public agencies. The IVN system installed in each vehicle provided navigational assistance as well as real-time traveler information detailing congestion, incidents, and traffic conditions at highway/rail intersections in the area. TransGuide used the Subcarrier Traffic Information Channel (STIC)-FM protocol to transmit the real-time information to the IVN units. Public agencies provided with the IVN units included fire departments, police departments, the City of San Antonio, Texas DOT, Texas Department of Public Safety, agencies using paratransit vehicles, and other agencies.

The total cost of the IVN project was $2,388,691. The majority of the project cost was attributed to the purchase of IVN devices which cost about $2,800 each. The IVN system was upgraded with a software application that added real-time traffic data. The cost of the software application development, $476,316, was another major cost driver. The total operations and maintenance (O&M) cost, $102,330, was a fraction of the deployment cost. Approximately 54% of the O&M cost was for IVN maintenance, database updates, and communication. The remaining O&M cost was shared cost with other TransGuide MMDI projects.

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.
