The report describes an automated block guidance vehicle control concept that meets the requirements for automatic fail-safe operation of short-headway transportation systems. The automated block guidance (ABG) concept represents a specific vehicle-follower approach to headway regulation and control for personal rapid transit and other short-headway passenger systems. The ABG is described in detail with reference to collision-avoidance control, vehicle overspeed protection and spacing control. Results of a detailed computer simulation to evaluate the performance of ABG control are presented. Derivation of the Collision Avoidance Constraint equations is appended. (Author)
