Intelligent traffic signal lamp anti-congestion method and device

Abstract

The invention discloses an intelligent traffic signal lamp anti-congestion method and device. The device comprises a server, a traffic flow monitoring module, a traffic flow prediction module, a traffic jam prediction module, a signal lamp control scheduling module and a signal lamp module. The traffic flow monitoring module collects vehicle model information, vehicle driving speed information, road traffic flow information and the number of vehicles waiting for a stop line of an intersection. The traffic flow prediction module and the traffic jam prediction module analyze and process the datamonitored by the traffic flow monitoring module to obtain a result, the signal lamp control scheduling module realizes scheduling; according to the intelligent traffic signal lamp anti-congestion method and device, the traffic flow monitoring module detects traffic flow information in real time and in multiple directions, real-time traffic flow prediction and traffic congestion prediction are achieved, the green light time is shortened when the traffic flow is small, the green light time is prolonged when the traffic flow is large, and the occurrence probability of traffic congestion is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic signal lamps, in particular to a method and device for preventing congestion of intelligent traffic signal lamps. Background technique [0002] With the continuous improvement of people's economic conditions, more and more vehicles are used. Traffic lights play a role in dredging traffic. The use of traffic lights can avoid traffic jams and reduce the occurrence of traffic accidents. [0003] At present, the traffic lights set at each intersection in domestic cities are almost all of a fixed duration, that is, the duration of the traffic lights set for the intersection is fixed, and the duration is generally set according to the average traffic flow of the road, and once After the setting is completed, it will not be easily changed in a long period of time, that is, regardless of the changes in the traffic flow at the intersection of this road due to any factors, for example, other roa...

[0003] At present, the traffic lights set at each intersection in domestic cities are almost all of a fixed duration, that is, the duration of the traffic lights set for the intersection is fixed, and the duration is generally set according to the average traffic flow of the road, and once After the setting is completed, it will not be easily changed in a long period of time, that is, regardless of the changes in the traffic flow at the intersection of this road due to any factors, for example, other road repairs, damages, etc. caused by abnormal conditions The traffic flow at the intersection is temporarily increased, and the duration of the traffic lights at the intersection will not change. The actual situation is that the traffic flow in each time period is different, and the traffic flow in the east-west direction and the north-south direction are different, resulting in a longer waiting time. The phenomenon of no vehicles passing through, eventually causing traffic jams
