A method, device, equipment and system for intelligent traffic control

Abstract

The embodiments of the invention disclose an intelligent traffic control method, device, apparatus and system and belong to the intelligent traffic management technical field. According to the intelligent traffic control method, device, apparatus and system of the invention, the length of congested vehicles on a first road is calculated according to acquired road condition information images; thenumber of newly added vehicles on the first road during unit time is calculated; and the vehicle release time of the first road is determined according to the number of the newly added vehicles, preset vehicle flow thresholds and standard release time corresponding to the preset vehicle flow threshold ranges, that is, the display duration of the green light of the traffic signal lights of the first road is determined. According to the method, device, apparatus and system of the invention, the vehicle passage time is adjusted according to vehicle flow, and therefore, the phenomenon of severe traffic congestion which is caused by a condition that vehicle flow on a road with large vehicle flow cannot fully pass the road within specified time which is further caused by fixed and identical traffic light switching time in the prior art can be avoided, congestion can be smoothened, and time waste and economic loss caused by traffic jams can be avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of intelligent traffic management, in particular to an intelligent traffic control method, device, equipment and system. Background technique [0002] With the rapid development of social economy and the improvement of people's living standards, the number of vehicles used as means of transportation and means of transportation has shown explosive growth. The sudden increase in the number of cars has brought great pressure to urban traffic. Especially during rush hours and holidays, the huge traffic flow makes the roads congested, which can easily lead to serious traffic jams, resulting in unnecessary waste of time and economic losses. Timely and effective traffic dredging is very necessary. [0003] Existing traffic control methods generally set the same and fixed time for the switching of traffic lights to realize the release of road vehicles. Under the regulation of this traffic ...

AI Technical Summary

Problems solved by technology

Under the regulation of this traffic control method, for the main road at the intersection, due to the large number of vehicles, the traffic flow cannot pass through within the specified time. Obviously, the clearance time is too short; while the auxiliary road has few vehicles, the time for all the traffic flow to pass Far less than the specified time, the vehicle release time is relatively long

In addition, in some special emergency traffic clearing demand scenarios, for example, ambulances are on the way to transport patients, or fire trucks are performing emergency tasks, due to the fixed vehicle release time and lack of effective emergency measures, it is impossible to Realize rush traffic in demand scenarios

It can be seen that the existing traffic control methods cannot achieve effective traffic dredging and solve the current situation of traffic jams.
