Abstract
This dissertation examines low-level control of an automated public transit system known as Personal Rapid Transit (PRT). This system consists of a large network of small (automobile-sized), computer-controlled vehicles. It provides passengers with ondemand, non-stop travel similar to a taxi. It should provide many benefits to individuals and society – greatly improved safety, reliability, and accessibility compared to the automotive system. Vehicles should also be more efficient in many respects: energy consumption, land usage, labour usage, and resource usage for construction of the system and vehicles. The idea dates back to at least the 1950’s. Various concepts and early prototypes are presented. A fairly common goal for PRT systems is to operate large numbers of vehicles at close spacings, which introduces safety issues. This thesis is primarily concerned with “lowlevel” control – the safe motion of vehicles. Various safety concepts from other transit systems are examined. These are compared to the needs of PRT. A methodology called “model follower ” is selected. In it, vehicle controllers plan trajectories of future motion
