Embodiment Construction

[0070] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited by the example embodiments described herein.

[0071] Application overview

[0072] The current research 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. Take a simple cross-shaped intersection as an example, assuming that the north-south entrance is the 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 an intersection unbalance degree analysis method and device, electronic equipment and a storage medium, and belongs to the technical field of traffic. The method comprises thefollowing steps: analyzing indexes influencing intersection imbalance indexes in detail, and determining each turning entrance lane imbalance index and each opposite entrance lane imbalance index in an intersection; and determining the weight between different imbalance indexes, improving the calculation formula of the intersection imbalance index to reflect the overall imbalance state of the intersection, judging whether to adjust the signal timing and / or phase setting of the intersection according to the relationship between the imbalance index and a preset threshold, and determining whetherto adjust the signal timing and / or phase setting of the intersection according to the relationship between the imbalance index. The method and the device are helpful for guiding the intersection to carry out signal timing optimization design, adjusting the phase and phase sequence, improving the traffic operation condition of the whole intersection, improving the vehicle operation efficiency, andguaranteeing the traffic safety.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a method, device, electronic device and storage medium for analyzing the imbalance 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 process of urban traffic signal control and optimization, a large number of professional traffic engineers are required to analyze and evaluate the operation state of each traffic intersection in the city, and find problems in the operation state of the traffic intersection for optimization work. [0003] Among them, the imbalance index is an index used to characterize the degree of imbalance between traffic volume and signal timing at the intersection, and the intersection imbalance index is used to characterize the imbalance between the traffic volume ...
