Traffic congestion-relief device for highways

摘要

The invention relates to the problem of wasted fuel when motor vehicles are in traffic jams, the reduction of the environmentally damaging engine exhaust gases and noise emissions. Remote-controllable traffic signals are installed from the point at which the traffic is impeded, counter to the direction of travel, at approximately 200-metre intervals from one another along the traffic jam and are connected to sensors in the vicinity of the traffic jam and at the point of obstruction by cables. If the flow of motor vehicles slows down to congestion speed or to a standstill, this is registered by the sensors and the first traffic signal switches to red (stop). The line of vehicles is stopped. After the red signal the vehicles move on. A large gap in the vehicles is produced. After a time interval which is determined by the flowing away of the vehicles in the section of the obstruction, the red signal is switched to green and at the same time the next traffic signal is remote-controlled to red. The vehicles between them now drive off and through the point of obstruction. The next group of vehicles follows and so on. If the last or first traffic signal shows green, all the vehicles held back before them drive on and through the point which is obstructing the traffic. If the vehicles back up again as far as the first signal or sensor, the group-based congestion relief starts again automatically from the beginning. (As long as the congestion relief device is in operation, all the signal generators, except for the operating ... Original abstract incomplete.
