The report discusses the functional requirements, basic design parameters and evaluation of a bus detector system developed for use in the urban traffic control system (UTCS) now being installed in Washington, D. C. The bus detector system makes possible the sensing of buses on the approach to an intersection so that preferential green extensions will favor their movement over private vehicular traffic. The system includes bus-mounted transmitters, loop antennas buried in the road and curbside receivers. Presence pulses generated by a receiver when a bus passes over the loop are transmitted over leased telephone lines to the UTCS control site. Here, a central computer processes both bus and separately supplied vehicular data in accordance with a bus priority algorithm to determine when green extensions are to be granted.
