Example Embodiment

[0071]Next, an exemplary embodiment according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present application, rather than all embodiments of the present application, to be understood, the present application is not limited by the example embodiments described herein.

[0072]Application overview

[0073]The current research generally believes that there is a direct relationship between the imbalance index and traffic, but there is no direct contact between the applicant's research, the imbalance index, and the traffic volume. Taking a simple cross-shaped intersection as an example, it is assumed that the import of North and South is In the imported road, there are two special left-turn lanes in the south. There is a dedicated left-turn lane, the south import left turn and the north import left turn belong to the same signal phase (simultaneous release, ...

Abstract

The invention discloses a characterization method and device for unbalance degree of each turning direction of an intersection, electronic equipment and a storage medium, and belongs to the technicalfield of traffic. According to the method, indexes influencing intersection imbalance indexes are analyzed in detail, and each turning entrance lane imbalance index and each opposite entrance lane imbalance index in an intersection are determined; and a calculation formula is improved to reflect the overall unbalance state of the intersection, whether signal timing and/or phase setting of the intersection is adjusted or not is judged according to the unbalance index, the intersection can be guided to conduct signal timing optimization design, adjust the phase and the phase sequence, so the traffic operation condition of the whole intersection is improved, the traffic safety of the intersection is improved, the vehicle running efficiency is improved, and the traffic safety is guaranteed. The problems that in existing intersection traffic analysis, definition of imbalance indexes is fuzzy, division is not comprehensive enough, the imbalance degree of an intersection is difficult to accurately measure, and intersection problem analysis is difficult to go deep are solved or partially solved.

Description

technical field [0001] The invention belongs to the technical field of transportation, and in particular relates to a method, a device, an electronic device and a storage medium for characterizing the unbalanced degree of steering at 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...
