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.
From the San Antonio MMDI Evaluation Report: Subsection 5.3.3 In-Vehicle Navigation Units Costs
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.
