Cabtrack: Communication and Control Instrumentation for a One-Fifth Scale Test Track.
ROYAL AIRCRAFT ESTABLISHMENT FARNBOROUGH (ENGLAND)
Pagination or Media Count:
Cabtrack is a proposed high-density urban transport system in which four-seat electrically powered vehicles run on a network of segregated tracks under automatic control. Passengers would be able, on demand, to travel non-stop between any two stations on the network. Feasibility studies were carried out and a new principle of position-lag slot control was proposed whereby vehicles would operate in synchronism with each other on main tracks, but change to asynchronous operation after diverting into a station loop. The model cabway has been successfully operated with six cabs of length 66 cm running at 2 ms with headways of 54 cm equivalent to a flow of 4000 cabs per hour on a track which is 70 occupied thereby demonstrating a viable system of control which could be developed for use with various types of vehicle on segregated tracks.
