Embodiment

[0038] A green wave evaluation method for arterial lines based on vehicle passing records at intersections is to evaluate the effective application of green wave on arterial lines by analyzing and processing the detection data of bayonet crossings at arterial intersections, such as figure 1 , the specific implementation steps are as follows:

[0039] S1. Data collection, relying on the smart bayonet detection equipment installed at the intersection entrance to obtain the passing detection data in the direction of the green wave control of the main line.

[0040] The specific implementation method of the data collection described in step S1 is: according to the green wave cooperative control range and the cooperative control direction of the trunk line, from the detection data of the smart bayonet detection equipment, the lane groups in the cooperative control flow direction of each intersection in the analysis period are screened out. Vehicle traffic detection data at the stop...

Abstract

The invention discloses a main line green wave assessment method based on intersection automobile passing records. The method comprises the steps that automobile passing detection data of the main line green wave control direction are obtained through intelligent crossroad detection equipment installed at an intersection entrance lane; an automobile passing signal figure of main line intersections in the cooperative control direction is generated on the basis of original automobile passing detection data; actual automobile passing situations of a main line green wave band within the analysis time period are preliminarily analyzed according to characteristic analysis of the automobile passing signal figure and the license number matching situations; the main line green wave utilization rate is analyzed and assessed according to the automobile passing signal figure and the automobile passing situations in the designed green wave band. According to the method, the intelligent crossroad serves as a traffic data source, no traffic detection equipment needs to be additionally installed, the automobile passing signal figure of the main line intersections in the cooperative control direction is generated on the basis of the automobile passing records of the crossroad, automobile passing characters of the intersections are analyzed, the main line green wave utilization rate is analyzed on the basis of the automobile passing characters, and the application effect of green wave control is assessed.

Description

technical field [0001] The invention relates to the field of traffic signal control, and relates to a method for evaluating green waves of trunk lines based on vehicle passing records at intersections. Background technique [0002] At present, intelligent bayonet electronic police equipment is widely used in various cities in China, especially at intersections with large traffic demands on urban main and secondary arterial roads. Based on license plate recognition technology, the monitoring and recording of passing vehicles at intersections is realized. The detection data of bayonet equipment for passing vehicles at intersections can reflect the actual operation of traffic flow at intersections and arterial lines. [0003] The purpose of implementing coordinated green wave control on main lines in cities is to increase the traffic rate of main lines, alleviate traffic congestion on main lines, and improve overall operating efficiency. The general green wave control of the t...
