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.
