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′min) by generating a signal (emin) and by driving the signal e
