Method and system for recommending coordination route and coordination scheme for urban traffic

Abstract

The invention relates to a method and a system for recommending a coordination route and a coordination scheme for urban traffic. The method is based on traffic state data. The traffic capacity of thebranch is ensured; control by coordination, phase differences of signal lamps are automatically set, parking time of vehicles at all intersections is shortened, so that it is guaranteed that when thevehicles arrive at all the intersections, the red light waiting time is minimum, particularly, the vehicles on a trunk line can run smoothly, urban traffic operation efficiency is improved, participation of personnel is reduced, and coordination routes of the intersections capable of being coordinated are automatically recommended. The output result of the method can be used for evaluating coordination route recommendation, and can also be used for outputting a coordination route recommendation scheme and implementing an actual urban traffic road section. By performing real-time coordinationcontrol on the urban traffic trunk line, the urban traffic flow can flow smoothly, and the modernization construction and improvement of the urban comprehensive traffic control capability are promoted.

Description

technical field [0001] The invention relates to the field of urban traffic, in particular to a method and system for recommending coordinated routes and coordinated schemes for urban traffic. Background technique [0002] In the urban road network, a large number of intersections are relatively close to each other. Inconsistent signal timing at adjacent intersections often causes vehicles to encounter green lights at upstream intersections and red lights at downstream intersections, resulting in massive queuing. Due to the short distance between intersections, the distance between two adjacent intersections is usually not enough to completely evacuate the traffic flow, and the queuing vehicles extend from the downstream intersection to the upstream, paralyzing the entire traffic system. In this way, vehicles stop and drive at intersections, resulting in poor traffic, low efficiency of road network operation, leading to problems such as increased environmental pollution and ...

AI Technical Summary

Problems solved by technology

At present, the control strategy adopted in our country has the following deficiencies: classified according to the control principle, the timing control strategy needs to manually set various parameters, and the efficiency is not high; while the induction control needs to set up a vehicle detector at the entrance of the intersection, according to the detection of the detector. The control method can be changed at any time based on the traffic flow information, but affected by the actual detector equipment and road conditions, there are often many missing data

This control method has the disadvantages of non-reproducibility, low efficiency and low reliability, and new technologies are urgently needed as auxiliary means to alleviate such problems
