Collision avoidance system

(57) -- a summary book collision prevention system supervises the speed and the position of vehicles for the collision related to vehicles called the collision with vehicles, vehicles, a pedestrian and vehicles, a train and vehicles, and a fixed thing -- (50) -- controlling -- (40) and (60) which are recorded and reported -- it prevents by things. This system reduces vehicles speed, or regulates movement of vehicles, and controls speeding, the violation of a move, and a specific dangerous action. This is realized by the controllable control machine 20 formed mainly in the road. This system supervises getting on and off of a pedestrian and a school bus, traffic, road surface moisture, and a traffic control system again. By having the capability to supervise the factor which suggests a possibility that various factors and collision related to a collision will take place, supervising traffic environment synthetically and prediction of a collision are attained. In order to realize observance of a traffic regulation, and reservation of safety, it is good to synchronize this system in combination with the existing traffic control system.
