Abstract

The invention discloses a lane function division method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a sum value of green light time ina single period of a lane with each function, and taking a product of a specific value of flow and quantity of the lane with the function and the sum value as effective green light time of the lane with the function for the lane with each function; according to the effective green light time of the lane of each function, a preset single-lane saturation flow rate, a preset signal lamp period lengthand a traffic capacity parameter calculation formula, determining the target number of each lane when the traffic capacity parameter takes the maximum value; and performing lane function division according to the target number of each lane. When lane function division is carried out according to the target number of each lane, the traffic capacity of the intersection is optimal, so that a problemof intersection congestion is solved to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to a lane function division method, device, electronic equipment and storage medium. Background technique [0002] With the development of urbanization, the problem of urban traffic congestion is becoming more and more serious, and the congestion phenomenon at road signal intersections is particularly serious. The unreasonable division of lane functions at intersections is an important reason for intersection congestion. For example, at an intersection where the flow of left-turning traffic is much greater than that of through-going traffic, if the number of left-turning lanes is less than that of through-going lanes, the functional division of left-turning lanes and through-going lanes will be unbalanced, and the traffic efficiency of the intersection will decrease, resulting in There is congestion at the intersection. [0003] Therefore, providing a reasonable lane function divi...
