Abstract

The invention provides a vehicle driving path dynamic navigation method based on a green light moment map, which can reduce the parking times and driving delay of a red light on a road and effectivelyimprove the reliability and stability of travel navigation. In the technical scheme of the invention, the final arrival time and the parking frequency of each feasible path are obtained based on thegreen light starting and ending time of each lamp control intersection on the path and the spatial distance between the lamp control intersections, and then the path evaluation index is established based on the path length, the final arrival time and the parking frequency of each feasible path, an optimal candidate path is obtained, and the to-be-navigated vehicle can be ensured reach the destination with the shortest driving time and the minimum energy consumption on the basis of considering the shortest path.

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...
