Summary Information

The Mobile Data Terminals study, published by the Transportation Research Board (TRB), defines the mobile data terminal (MDT) as "a multifunctional data collection device on board transit vehicles that performs two-way data communication and, increasingly, has the ability to locate itself in real time."

Based on survey results from over 100 transit agencies and equipment suppliers, the trend in mobile data terminals (MDTs) is toward more functionality at lower unit, installation, maintenance, and repair costs. An MDT collects various onboard data and support two-way communication between the transit vehicle and the control center. Excerpted from the source study, the MDT functionality and deployment costs at selected transit agencies are presented below.

The majority of MDTs are used to download driver manifests, collect driver data such as sign on/sign off and start run/end run, count passengers boarding and alighting, and to function as an emergency alarm. The majority of the transit agencies participating in the survey reported capital costs for MDTs in the range of $1,000 to $4,000 per unit, with installation costs in the $500 to $1,000 range.
