Intelligent traffic light control system based on human traffic detection

Abstract

The invention discloses an intelligent traffic light control system based on human traffic detection and relates to the technical field of intelligent traffic. The system comprises a traffic light module, a human traffic and motor vehicle detection module, a human traffic counting display module, an alarming module and a time-delay module, the system takes infrared sensors as cores and takes an STC89C52 microcontroller as a basic control device of the system, the traffic light is automatically controlled by using human traffic data which is monitored by the infrared sensors on two sides of a pedestrian crossing so that duration change can be displayed suitably, and the infrared sensors are arranged on a left-turn lane to detect whether or not a motor vehicle alarms to remind pedestrians of taking care. The intelligent traffic light control system based on human traffic detection effectively solves crowd traffic especially traffic problems in particular to jammed intersections and collision of pedestrains and motor vehicles, and has good application prospects and significance.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic, and more specifically, relates to an intelligent traffic light control system based on detection of human flow. Background technique [0002] The intelligent traffic light control system combines traffic technology with the Internet of Things. It is a dynamic traffic control system based on real-time traffic information. Through intelligent equipment, the system can distribute the lighting time of traffic lights more reasonably, which is different from the traditional traffic lights. Fixed periodic sequence manipulation duration. Intelligent traffic light control has the advantages of automatic control, which can more effectively alleviate various traffic problems such as traffic congestion, especially intersection congestion. [0003] The problem of pedestrian congestion and safety guarantee at urban road intersections is becoming more and more serious. With the increase of traffic ...

AI Technical Summary

Problems solved by technology

At present, fixed cycle traffic lights are mainly used to guide the crowd at the intersection, and it is impossible to effectively adjust the duration of the green light cycle sequence in real time according to the actual traffic flow; when the current intersection shows the green light for the current pedestrian crossing, the motor vehicles in the left turn lane also show the green light to pass , which will cause collisions between pedestrians and left-turn motor vehicles, leading to frequent pedestrian crossing accidents

[0004] The monitoring camera used in the current human flow detection module sends the obtained video to the digital image processor, and displays the human flow through image processing. The system structure is complex and the cost is high, and the advantages of intelligent traffic lights based on human flow detection cannot be effectively utilized.
