The movement route of a vehicle operative with a roadway track having a plurality of stations and control signal gates is selected from a storage table of predetermined available routes in accordance with the known track plan and in relation to each station. When the vehicle arrives at each of the stations, the desired available route is established to the next station in relation to occupied track signal blocks, the known direction of train movement and switch gates cleared to permit vehicle travel to that next station. The available route to the next station is cleared in time so the vehicle will not have to slow down or stop in front of a switch gate. In addition the spacing of vehicle trains is regulated in relation to the plurality of stations.

Vehicle train routing apparatus and method

A vehicle train tracking apparatus and method are provided for responding to detected occupancies and unoccupancies of each of a plurality of signal blocks of a roadway track system to establish a position or location record of the movement of each vehicle train operating with the roadway track system.

Vehicle train tracking apparatus and method

There is disclosed a vehicle train control apparatus and method for controlling the operation of a vehicle train by a second control equipment provided in a different control vehicle of the train in the event of the failure of the train control equipment of a first control vehicle initially selected to control the train.

Transit vehicle handback control apparatus and method

A passenger vehicle door control apparatus and method, including programmed computer control apparatus responsive to open door code signals from the wayside in addition to a zero signal to indicate that the train of vehicles has stopped within a passenger station are operative to open the doors of all vehicles at the correct time on the correct side of the train when the train is within the station and traveling at less than a predetermined zero speed.

Door control for train vehicles

A speed decoding and error determining control apparatus and method are disclosed, including two independently programmed microprocessors responsive to a desired speed command from the wayside for determining respective speed errors for a coupled passenger vehicle, which speed errors must compare within a predetermined tolerance before the speed command is permitted to control the actual speed of the passenger vehicle.

Speed decoding and speed error determining control apparatus and method

There is disclosed a passenger vehicle operation control apparatus and method, including programmed microprocessor control apparatus for determining an improved and more precise stopping of each vehicle in relation to a station platform.

Program stop control of train vehicles

An improved train vehicle speed control system is provided for operation in conjunction with train vehicle occupancy control signals and train occupancy indication signals in relation to a train vehicle track system including a plurality of predetermined track circuit signal blocks through which the train vehicles pass. It is desired that control of train vehicle speed be provided in relation to the detected occupancy by the train vehicle in a particular signal block, for maintaining train vehicle occupancy protection requirements and providing protection signals to establish desired sequential occupancy control of the train vehicles through each of selected signal blocks adjacent to that particular signal block. Spurious pseudo vehicle occupancy in any signal block is detected and included in the provided train speed control in relation to that signal block. The provided train vehicle occupancy control signal is determined in relation to the provided occupancy indication signal, predetermined protection signals and the unique features of the signal block in which train vehicle occupancy is detected.
