Embodiment 1

[0021] Embodiment 1: The entrance vehicle statistics unit records the number of all vehicles on the nearest section of the road in the current X direction. This can be achieved by designing a camera at the last traffic intersection to record the number of vehicles turning left, the number of vehicles entering right and the vehicles entering straight number, and then add the three vehicle numbers together to obtain the number of all vehicles on the X-direction road segment.

[0022] The most preferred solution, according to a similar principle, the entrance vehicle statistics unit can record the number of all vehicles traveling in the X direction, the number of vehicles traveling in the negative X direction, the number of vehicles traveling in the Y direction, and the number of vehicles traveling in the negative Y direction at this intersection. The number of all vehicles; the export vehicle statistics unit can use the GPS positioning method or the vehicle navigation method to o...

Abstract

The present invention discloses an artificial intelligence system for distribution of a traffic light based on a dynamic traffic flow, belonging to the field of traffic light management. The system comprises an entrance vehicle statistics unit, an exit vehicle statistics unit, an optimum time distribution unit and a signal light control unit. The entrance vehicle statistics unit is configured to perform statistics of the total number of vehicles which enter a road section; the exit vehicle statistics unit is configured to calculate the number of vehicles located in a straight lane, a left turning lane and a right turning lane in the road section; and the optimum time distribution unit is configured to perform optimum distribution of the number of all the vehicles at a crossroad, the numberof vehicles which are going to out in each lane and the total time T required to complete the whole crossroad, wherein the optimum distribution is performed by employing a weighting proportion mode.The artificial intelligence system for distribution of the traffic light based on the dynamic traffic flow can perform real-time regulation of pass time of vehicles at a green light and is convenientto evacuate jamming vehicles.

Description

technical field [0001] The invention mainly relates to the field of traffic light management, in particular to an artificial intelligence system for allocating traffic lights based on dynamic traffic flow. Background technique [0002] In the prior art, the setting time of the traffic lights at the crossroads is basically constant, at least relatively constant for a period of time, which is very unfavorable for the management of vehicles during peak hours of commuting and commuting. Therefore, there is an urgent need to design an artificial intelligence system that can dynamically allocate green light time periods according to the relative number of vehicles at the local intersection. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides an artificial intelligence system based on dynamic traffic flow, real-time adjustment of vehicle green ...
