Abstract
A speed control system for controlling vehicle speed of one or more vehicles in a personal rapid transit system when the one or more vehicles travel along a track, the personal rapid transit system including a vehicle propulsion system including one or more motors, each motor being adapted to generate a thrust for propelling one of the one or more vehicles. The speed control system includes: a speed regulation subsystem adapted to control the thrust generated by at least one of said motors based on one or more sensor signals received from vehicle position and/or speed sensors, so as to control the speed of the one or more vehicles; and a vehicle control system included in each of said one or more vehicles and adapted to activate, independently from the speed regulation subsystem, an emergency brake mounted on said vehicle.
