A device and method for guiding vehicles to pass through an intersection without stopping based on a vehicle speed induction strategy

Abstract

The invention discloses a device and method for guiding a vehicle to pass across an intersection without stopping based on vehicle speed induction strategy, and belongs to the field of urban transportation control and automobile auxiliary driving. The method is characterized by, to begin with, a signal machine control unit receives real-time signals and position signals of traffic lights at one intersection in real time, adapts to non-periodically-changing timing information and provides road traffic information ahead; then, data transmission is realized between the signal machine control unit and a vehicle-mounted control unit zigbee wireless transmission unit; and finally, according to the obtained data information, a vehicle-mounted control unit generates a vehicle control strategy in real time according to different driving conditions to guide vehicles to speed up or slow down to pass through the intersection without stopping. The device and method realize the effect that the vehicle can reach and pass through the intersection within the green light phase, ensure the vehicle to pass through the intersection without stopping, overcomes the problems of congestion and too much delay, improve discharge capacity of the intersection, and are easy to operate.

Description

technical field [0001] The invention belongs to the field of urban traffic control and vehicle assisted driving, and in particular relates to a device and method for guiding vehicles to pass through an intersection without stopping based on a vehicle speed induction strategy. Background technique [0002] A large number of facts show that the congestion of urban intersections is the most serious, more than 80% of the delays are concentrated in urban road intersections, and the traffic capacity of level intersections is less than 50% of the roads. Generally speaking, vehicles entering an intersection often have to change their driving state due to the action of signal lights, and both complete and incomplete parking will cause the loss of vehicle running time. The intersections controlled by traditional signal lights have many drawbacks, so that when vehicles approach or pass through the intersections, it is easy to cause road congestion, and even traffic accidents will occur...
