Intelligent traffic signal lamp control device capable of performing autonomous switching according to zebra crossing flow

Abstract

The invention discloses an intelligent traffic signal lamp control device capable of performing autonomous switching according to a zebra crossing flow. A plurality of vehicle identification cameras are respectively mounted at a crossing in directions of facing a crossing driving-in direction of vehicles in a road, and performs identification, calculation and statistics on kinds, number, driving speeds and current positions of the vehicles on the road and passenger states, and then transmits the real-time statistics data in different directions to a local traffic controller through a netting twine. The local traffic controller performs real-time optimization and traffic controlling according to real-time statistics data of each road in the crossing, the preset vehicle kind and road priority and an optimization target. The intelligent traffic control device performs traffic optimization according to the priority of each lane and each vehicle and controls the traffic signal in each direction so that the signal lamp is synchronous with the driving vehicles on the road, thereby sufficiently using an existing road resource, reducing the number of stopping times of the vehicle and time length, improving a traffic jam state, reducing exhaust gas pollution and realizing intelligent traffic control.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to an intelligent traffic signal light control device that can switch autonomously according to the flow of a zebra crossing. Background technique [0002] The traffic light time of the existing traffic control system is basically set by experience, and the control mode is fixed time according to the period. The traffic control signals at these intersections will not be adjusted in real time according to changes in traffic flow, and there are often red lights in directions with cars, and green lights in directions without cars for a long time. The fact that the actual road vehicle status and traffic control signals are not synchronized will increase the number and time of vehicle stops, waste existing road resources, worsen traffic congestion, and increase energy consumption and exhaust pollution. [0003] In order to improve road traffic conditions, some traffic intersections...

AI Technical Summary

Problems solved by technology

This out-of-synchronization between the actual road vehicle status and traffic control signals will increase the number and time of vehicle stops, waste existing road resources, worsen traffic congestion, and increase energy consumption and exhaust pollution.

[0003] In order to improve road traffic conditions, some traffic intersections will have traffic police and other manual command during peak hours. The purpose is to optimize and adjust traffic control signals according to the real-time conditions of the road, because the traffic police can see the real-time traffic status of vehicles and pedestrians at the intersection. , but it is unrealistic for every intersection to be commanded by someone 24 hours a day. In view of the above situation, technological innovation should be carried out on the basis of existing traffic control devices
