Arterial coordination control method based on traffic wave under road section construction area background

Abstract

The invention discloses an arterial coordination control method based on the traffic wave under the road section construction area background. The method includes the following steps of firstly, establishing a traffic wave model capable of reflecting features of a construction area; secondly, calculating parking delay of each crossing under the road section construction area background; thirdly, establishing a dual-target arterial coordination model with the main target of the minimum coordination phase parking delay and the auxiliary target of the minimum crossing parking delay under the constraint condition of no overflow of coordination phase queueing vehicles. Compared with the prior art, the method has the advantages that the influences on the vehicle speed probability distribution, arrival rate and queueing vehicle length and time in the presence of the construction area are sufficiently considered, and the arterial coordination model based on the traffic wave under the road section construction area background is established. By means of the method, the more accurate arterial coordination result is obtained, the traffic delay caused by the construction area is reduced as much as possible, and the traffic capacity of a construction area road section is effectively improved.

Description

technical field [0001] The invention relates to a traffic wave-based arterial coordinated control method under the background of road section construction areas. Background technique [0002] There are a large number of construction areas in urban roads in many countries, and these construction areas have a great impact on urban traffic. Construction areas compress road resources, increase high traffic delays and travel costs, and may also cause high-frequency traffic accidents. The existence of construction areas on urban road sections will change traffic parameters such as arrival rate, departure rate, and average vehicle speed at intersections, making the original signal control scheme in urban roads no longer applicable, resulting in delays and increased parking times. It is very important to study the coordinated control scheme of the arterial line under the influence of the construction zone to alleviate the negative impact of the construction zone on urban traffic. ...

AI Technical Summary

Problems solved by technology

Although the arterial coordinated control model itself is relatively mature, the existence of the construction zone has changed, which will not only reduce the traffic capacity of the road section, but also change the vehicle release at the upstream intersection and the vehicle arrival rate model at the downstream intersection, making the original Signal timing scheme no longer applicable
