ABSTRACT:
Safe separation distances between automatically controlled vehicles moving at short headways on a guideway are maintained through the cooperative action of a block control system and reflectometer (radar) and transponder (beacon) intervehicle distance measuring equipment installed in vehicles. A reflectometer determines distance to a leading vehicle through measurement of the delay between a transmitted signal and a received signal relayed by a transponder in the leading vehicle. A transmission line acts as the medium of transmission. Problems associated with non-transponder-equipped reflectometers are obviated. In the event of transponder malfunction, the block control system maintains backup safety regardless of transponder activity in other vehicles. Exessively short block lengths generally required for short-headway maintenance by block control systems are not required. Merge protection is effected through the cooperative action of the block control system and stationary reflectometers, installed at the wayside, which measure distances to merging vehicles through interaction with transponders located in the vehicles.
