Embodiment Construction

[0070] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0071] Application overview

[0072] The research at the current stage generally believes that there is a direct relationship between the imbalance index and the traffic volume, but according to the applicant's research, there is no direct relationship between the imbalance index and the traffic volume. Taking a simple cross intersection as an example, assuming that the north-south entrance is opposite To the entrance road, there are two dedicated left-turn lanes at the south entrance, and one dedicated left-turn lane at the north entrance. The left turn at t...

Abstract

The invention discloses a method, device, electronic equipment and storage medium for analyzing the unbalanced degree of an intersection, and belongs to the technical field of traffic. This method makes a detailed analysis of the indicators that affect the imbalance index of the intersection, and determines the imbalance index of each turning entrance and the opposite entrance in the intersection; The calculation formula of an index is improved so that it reflects the overall imbalance state of the intersection. According to the relationship between the imbalance index and the preset threshold, it is helpful to judge whether to adjust the signal timing and / or phase setting of the intersection. Optimal design of signal timing at intersections, adjusting phase and phase sequence, improving the traffic operation conditions of the entire intersection, improving vehicle operating efficiency, and ensuring traffic safety.

Description

technical field [0001] The invention belongs to the technical field of transportation, and in particular relates to a method, device, electronic equipment and storage medium for analyzing the unbalanced degree of an intersection. Background technique [0002] With the rapid development of urbanization, the scale of cities is increasing day by day, and the number of signal-controlled intersections is also increasing year by year. In the optimization of urban traffic signal control, a large number of professional traffic engineers are required to analyze and evaluate the operation status of each traffic intersection in the city, and find problems in the operation status of traffic intersections for tuning work. [0003] Among them, the imbalance index is used to characterize the degree of imbalance between traffic volume and signal timing at intersections, and the intersection imbalance index is used to characterize the imbalance between traffic volume and signal timing in the...
