ABSTRACT:
Each train detects its location, velocity, and the time it will spend to pass the next bifurcation, joint, and intersection, respectively, and sends the information periodically to the trains that are or will be behind the train. The controller of each bifurcation, joint, and intersection, respectively, having mechanical movement sends the connection status of the track to the trains about to pass it. Then, receiving a message, a train can determine if it may hit its front train if its front train stops abruptly and if it may pass the bifurcation, the joint, and the intersection, respectively, before the track there has been connected for it. If yes, the train decelerates to stop to avoid possible disasters. So that the distance between every two consecutive trains can be minimized and different kinds of trains may share the same railroad. Hence, some railroads may be saved. Furthermore, multiple trains and buses can be arranged to arrive at or depart from a station at close moments of time and each bus stops at small number of stops. Hence significantly shorten the time each passenger spends on commuting.
