Abstract
A technique for avoiding collisions between trains includes equipping a plurality of trains each with a transceiver and broadcasting a signal periodically from the transceiver of each train. The signal contains a unique identification of a respective train and a unique identification of a track the respective train is moving on. The transceiver of each train receives the signal broadcasted by each of the other trains within a given range. The received signals are analyzed to extract the unique identification of each other train and the unique identification of the track each other train is moving on. It is determined if the track of the train receiving the signal and any of each other trains within the given range is the same and providing an indication if the track of the recipient train and any of other train within the range is the same.
