Abstract

See full text

An embedded system controller-based vehicle tracking system using vehicle positioning. An embedded system controller controls a traffic intersection using an optical system. The embedded system controller receives a vehicle location and a vehicle schedule. The embedded system controller calculates whether the vehicle is on time and reports the on-time status to the driver interface. The driver may -request that the system report a panic or emergency situation to the dispatch center through an external data communications network. The external data communications network may also send vehicle status, such as vehicle position and vehicle condition. A transit company using the system may provide vehicles equipped with the vehicle tracking system with schedules on a daily basis, using a portable data transfer device. The embedded system controller also communicates to the vehicle data network for the communication of vehicle position. A global positioning system receiver may be used to provide the position of the vehicle to the embedded system controller.
