APTS01-Transit Vehicle Tracking (Market Package*)

Market Package Graphic       Transaction Set Diagram

Description

This market package monitors current transit vehicle location using an Automated Vehicle Location System. The location data may be used to determine real time schedule adherence and update the transit system’s schedule in real-time. Vehicle position may be determined either by the vehicle (e.g., through GPS) and relayed to the infrastructure or may be determined directly by the communications infrastructure. A two-way wireless communication link with the Transit Management Subsystem is used for relaying vehicle position and control measures. Fixed route transit systems may also employ beacons along the route to enable position determination and facilitate communications with each vehicle at fixed intervals. The Transit Management Subsystem processes this information, updates the transit schedule and makes real-time schedule information available to the Information Service Provider.

Early Deployment

This market package has been identified as an early deployment due to a promising combination of low risk implementation characteristics, developing public or private markets for the package, and tangible system or user benefits. This Market Package provides the communications between vehicles and transit centers and current vehicle location information that is required by other packages. The technology of Automatic Vehicle Location is proven and in use by many transit agencies. While insufficient data exists at this time to validate transit benefits, its usage in commercial transportation such as the trucking industry has shown it to be beneficial.
