The invention provides a self-adapting quick
response system for urban
traffic congestion, comprising a center
system, a roadside
detector, a roadside detection controller, a
dynamic display board on the road and an information subsystem, wherein the center
system is used for
processing information which is transferred by the roadside
detector and the roadside detection controller which are connected with the center
system and returning results after analyzing the information; the roadside
detector is used for detecting the
road traffic state by utilizing a comprehensive
inductor and sending detection results back to the center system as well as the adjacent roadside detector and roadside detection controller; the roadside detection controller is used for detecting and analyzing the relevant
traffic flow and the congestion state of the road section or the
road junction and controlling the traffic light length, a
wireless shirt-distance information publishing device and the dynamic information board; the
dynamic display board on the road is used for intercommunicating information with the center system and the adjacent roadside detection controller and dynamically displaying the information after being analyzed; and the information subsystem is connected with the center system and used for pertinently
broadcasting traffic information to drivers through various ways. By means of the system provided by the invention, the possible congestion can be rapidly detected and controlled to ensure that the congestion is eradicated at the beginning of forming.
