Wireless advanced automatic train control

Communication devices and network techniques are combined in a radio system under development to satisfy safety critical, operational requirements for train location and control in railroad and transit applications. Spread spectrum radios, installed on-board trains, at wayside locations, and at control stations, participate in a synchronous, time slotted network enabling location determination in conjunction with reliable transfer of control information. Simulations have shown that the benefits of this radio based advanced automatic train control system are appreciable reductions in operational headway, in energy consumption, and in elapsed time for consists to traverse their routes.<
