[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

Embodiment approach
[0123] First, only compare the state of the first lane of this round with the state of each second lane of this round, and use the lane state corresponding to the minimum average delay of vehicles at the intersection as the final target lane state;
[0124] Second, it can also be considered to compare the states of the second lanes of this round first, and then compare the state of the second lane with the smallest average delay value of vehicles at the intersection with the state of the first lane of this round. Finally determine the target lane state;
[0125] Third, it is not limited to only comparing the state of the first lane of this round and the state of each second lane, but adopts the concept of multi-round comparison, that is, if the average delay value of vehicles at the intersection of a certain second lane is the smallest and is not greater than the first The average delay value of the intersection vehicle in the first lane state, then the second lane state can b...

The invention discloses a method, device and equipment for generating intersection lane functions, wherein the method includes: obtaining the average vehicle delay at the intersection for the current lane state according to the pre-built simplest lane state and the corresponding optimal signal control strategy value; based on the current lane state, obtain other lane states related to it and the corresponding average vehicle delay value at the intersection; compare the average vehicle delay value at the intersection of each lane state, and use the lane corresponding to the minimum average vehicle delay value at the intersection state, to determine the final intersection lane function. The present invention aims at minimizing the average delay of vehicles at intersections, and can effectively realize the optimal combination of optimal lane function division and corresponding signal control schemes. Compared with existing lane function division schemes, the present invention has better universality , and there is no need to exhaustively enumerate all combinations of lane states.
Description
technical field [0001] The invention relates to the field of traffic signal control, in particular to a method, device and equipment 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 the pressure on urban road traffic is increasing. The development of the city had a significant 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 determined based on specific lane function divisions. Strategy. [0003] The so-called lane function division (for ease of expression, the present invention is a...
