Intersection lane function generation method, device and equipment

Abstract

The invention discloses an intersection lane function generation method, device and equipment, and the method comprises the steps: obtaining an intersection vehicle average delay value for a current lane state according to a pre-built simplest lane state and a corresponding optimal signal control strategy; acquiring other lane states related to the current lane state and a corresponding intersection vehicle average delay value based on the current lane state; and comparing the intersection vehicle average delay values of the lane states, and determining a final intersection lane function by utilizing the lane state corresponding to the minimum intersection vehicle average delay value. The optimal combination of the optimal lane function division and the corresponding signal control schemecan be effectively realized by taking minimization of the average delay of vehicles at the intersection as the target, and compared with the existing lane function division scheme, the method has better universality and does not need to exhause all lane state combinations.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a method, device and device for generating intersection lane functions. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of the national income level, motor vehicles have become a common tool for people to travel. In recent years, the number of motor vehicles in my country has continued to increase, and urban road traffic pressure is increasing. The constraints of urban road hardware resources have The development of the city had an important impact. How to improve the utilization of urban roads in space and time is of great significance to traffic travel. From this, a variety of intersection signal control strategies are derived, and the determination of signal control schemes often needs to be based on specific lane function divisions to determine the best Strategy. [0003] The so-called lane function divisio...

Problems solved by technology

[0005] Although the other type divides the function of lanes at intersections from the perspective of signal control strategy, it is often limited by the fixed intersection shape and the number of entrances, and when using the timing scheme to divide lane functions, The exhaustive method is often used to list various lane function combinations, which not only increases the calculation cost, but also makes the division result poor
