This paper examines the effects of spacing policy and control system design on the dynamic response of strings of automated transit vehicles operating under vehicle-follower control. Constant-separation, constant-time-headway and constant-safety-factor spacing policies are implemented and their operational implications are discussed. The dynamic response of a string of five vehicles during speed changing, merging, emergency stopping, and failed-vehicle pushing is examined.
