ABSTRACT:
The vehicle-mounted transmitter unit triggers a reset signal in the stationary receiver unit when the vehicle passes in sufficiently close proximity to the stationary unit. A display connected to the stationary unit tells waiting passengers or riders when to expect the next vehicle to arrive, by presenting either time of day at which last vehicle arrived or elapsed time since last vehicle arrived.
