Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0041]Generally, a junction may be connected with many roads, but any junction on a city road often has two roads as arterial roads, and at most there are only two arterial roads. When congestion occurs at each traffic intersection of urban roads, since the traffic flow on the arterial road is usually the largest, it is often the two most congested roads, and their traffic pressure is the greatest; It avoids congestion and is more conducive to alleviating the con...

Abstract

The invention discloses an intelligent control method of a traffic light of an urban main road. The method comprises: according to an intersection serial number carried by a linked control request from a congestion intersection, a main road intersection state table is queried to obtain a first main road identifier and a second main road identifier of the current intersection and an upstream adjacent intersection and a downstream adjacent intersection of each main road of the current intersection; with an inflow vehicle traffic detection and an outflow vehicle traffic detector that are arranged at each main road section at the main road direction, the numbers of vehicles that are going to pass through the current intersection and upstream and downstream adjacent intersections of the main road and vehicle traffic capacities per unit time of the current intersection and upstream and downstream adjacent intersections are obtained; according to the number of all vehicles that are going to pass through the intersection and the vehicle traffic capacities per unit time, needed vehicle passing time of the current intersection and the upstream and downstream adjacent intersections at the main road is determined; and on the basis of needed vehicle passing time, green light linked control time of the current intersection and the upstream and downstream adjacent intersections at the main road is determined to carry out linked control. According to the invention, vehicles on the main road can be guided rapidly and the worsening traffic congestion can be prevented.

Description

technical field [0001] The invention relates to the field of intelligent traffic signal control in smart cities, in particular to a method capable of intelligently controlling traffic signal lights at the traffic intersection according to the traffic conditions at the intersection. Background technique [0002] Since the 1980s, China's urbanization process has continued to advance. In large cities such as Beijing, Shanghai, Guangzhou, Shenzhen, and even some small and medium-sized cities, the number of motor vehicles has increased rapidly, and urban road congestion has become increasingly serious. In order to ensure the normal operation of vehicles between urban roads, traffic lights must be set at each road intersection to control the passing vehicles. The traffic signal control at the intersection is mainly realized by the traffic signal controller. Therefore, traffic signal controllers play an increasingly important role in daily life. [0003] Usually, the control of t...
