VEHICLE FOLLOWER LONGITUDINAL CONTROL FOR AUTOMATED GUIDEWAY TRANSIT VEHICLES

Continuing interest in the use of public transit to help solve problems related to urban transportation has pointed to the use of relatively small automated transit vehicles as a method for providing expanded transit service without the labor costs and reliability problems associated with the bus and without the high capital costs associated with rapid rail systems. Two philosophies for longitudinal control for short headway automated guideway transit (AGT) systems have evolved - (1) the vehicle-following concept, and (2) the point-following concept. This study is concerned with vehicle-follower control at relatively short headways. The objective of this research is to examine basic considerations in vehicle-follower longitudinal control for small, automated transit vehicles operating at moderate speeds and short headways. The relationship between spacing policy, system nonlinearities, and dynamic response of strings of vehicles is discussed.
