A traffic signal light indicating system

Abstract

Disclosed in the invention is a traffic signal lamp indication system comprising a PLC control part, a piezoelectric part, a sensor part and a signal lamp indicator part. The piezoelectric system is installed at a right side passageway of a road. The sensor part is formed by a pressure sensor and is installed at the piezoelectric ceramic top of the piezoelectric part. The signal lamp indicator part is formed by a vehicle running signal lamp, a digital signal lamp, and a pedestrian signal lamp; and the vehicle running signal lamp can display two kinds of colors of the red color and the green color, wherein the red color represents information of no entry and the green color represents information of going. The piezoelectric part, the sensor part, and the signal lamp indicator part are connected to the PLC control par by cables. According to the invention, on the basis of the principle that when first comes at an intersection, first passes through the intersection, vehicles can pass through the intersection rapidly with high efficiency. Meanwhile, the piezoelectric part is installed at the intersection and the pressure of the vehicle is changed into electric energy, so that the energy is effectively utilized. The system has the broad application prospects.

Description

technical field [0001] The invention relates to a traffic signal management system, in particular to a traffic signal lamp indicating system, which belongs to the technical field of traffic management. Background technique [0002] The current traffic signal light system almost always controls the passage of vehicles at a fixed time interval, so there are the following disadvantages: (1) When the traffic flow in the two directions of the intersection is very different, there will be no vehicles or vehicles passing through in the lateral direction. In the case that all vehicles have passed through, the vehicles coming vertically have to wait for the red light, causing a lot of energy loss and air pollution; (2) The adjustment of red and green time is not perfect, and it cannot effectively deal with vehicle congestion during peak hours; The paradox of waiting for the green light. (2) In places far away from the town, there are many bends with traffic accidents, but the curren...

[0002] The current traffic signal light system almost always controls the passage of vehicles at a fixed time interval, so there are the following disadvantages: (1) When the traffic flow in the two directions of the intersection is very different, there will be no vehicles or vehicles passing through in the lateral direction. In the case that all vehicles have passed through, the vehicles coming vertically have to wait for the red light, causing a large amount of energy loss and air pollution; (2) The adjustment of red and green time is not perfect, and it cannot effectively deal with vehicle congestion during peak hours; The paradox of waiting for the green light

(2) In places far away from the town, there are many bends with traffic accidents, but the current traffic signal light system is difficult to apply; (3) With the existing traffic signal light system, the vehicle needs to start at the intersection, and the speed is relatively slow
