Embodiment Construction

[0092] The present invention provides a dynamic navigation method for vehicle driving paths based on a green light time map, which is characterized in that it includes the following steps.

[0093] S1: Search for all feasible paths according to the starting point and end point of the vehicle to be navigated; in the technical solution of the present invention, all possible feasible paths are calculated based on the A* algorithm. Compared with other algorithms, the A* algorithm has better search efficiency and can ensure this The calculation efficiency of the method technical scheme is higher;

[0094] Calculate all feasible paths P between the starting point SP and the ending point EP based on the A* algorithm 1 ,P 2 ,...,P n , and the corresponding path length L 1 , L 2 ,...,L n The process includes the following steps:

[0095] a1: Initialize an open list OpenList; put the starting point into the open list OpenList;

[0096] a2: set the starting point as the detection ...

Abstract

The invention provides a dynamic navigation method for vehicle driving paths based on a green light time map, which can reduce the number of stops and driving delays when encountering a red light, and effectively improve the reliability and stability of travel navigation. In the technical solution of the present invention, based on the start and end time of green lights of each light-controlled intersection on the path and the space distance between light-controlled intersections, the final arrival time and number of stops of each feasible path are obtained, and then based on the path of each feasible path Length, final arrival time, number of stops, establish a route evaluation index, and obtain the best candidate route; ensure that the vehicle to be navigated can take into account the shortest route, and use the shortest driving time and minimum energy consumption to reach the destination.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a dynamic navigation method for vehicle driving paths based on a green light time map. Background technique [0002] Traditional route navigation methods usually only consider factors such as distance, time, and road conditions, while ignoring the influence of signal light control, and can only calculate a relatively optimal path in an uncontrolled state; and users drive based on such navigation results. Sometimes, it is often hindered by the control of signal lights at intersections. From the perspective of driving time and energy consumption, it is not really the best navigation result. Contents of the invention [0003] In order to solve the problem that the existing navigation method does not consider the factors influenced by the signal light, resulting in a non-optimal navigation result, the present invention provides a dynamic navigation method for ve...
