ABSTRACT:
A vehicle-follower control law for short headway automated guideway transit systems is implemented to provide an apparently optimal system in light of sensor accuracy, controller structure, and data transmission requirements. In particular, the spacing between two vehicles on a guideway is forced to an approximate optimal minimum value (S'.sub.min) by generating a signal (.epsilon.) which is the difference between the actual spacing (S) and the approximate optimal minimum spacing (S'.sub.min) and by driving the signal .epsilon. to zero according to a predetermined control law. In accordance with the invention, a constant headway or constant K-factor design can be employed in defining the control law. Embodiments for 0.5 second and 3 second headways are provided.
