Urban traffic light system and traffic management method

Abstract

The invention discloses an urban traffic light system. A BIM operation and maintenance server is placed in a remote monitoring center, a traffic signal light control unit is installed on a lamp pole, the traffic signal light control unit comprises a control device, a voice device, an infrared sensor, a zebra crossing traffic signal light, a camera device, an underground vehicle induction coil and a network communication device, wherein the infrared sensor is used for identifying whether pedestrians occur on zebra crossing or not, the control device is arranged to calculate the time for an adult to cross a street at a normal speed according to the width of the street, and to respond to an identification result of the infrared sensor and to control entering of at least one of two kinds of traffic signal light period-dividing control modes in a current time quantum. According to the urban traffic light system and a traffic management method, the time-sharing control modes are utilized to control signal lights, thus the safety of the pedestrians is guaranteed, the time for a car owner to wait for the red light is shortened, the problem of urban traffic congestion is solved, and the accident occurrence rate is lowered.

Description

technical field [0001] The invention relates to the field of traffic lights, in particular to an urban traffic traffic light system and a traffic management method. Background technique [0002] With the rapid development of cities, the number of vehicles is increasing, and there are more and more traffic jams and traffic chaos accidents. Common traffic lights are mostly timed. The time of red, yellow and green lights is fixed. This kind of traffic lights is not safe enough. When the road is too wide, pedestrians, especially the elderly or children, often walk on the road when the road is too wide. In the middle of the road, it is easy to crash and cause traffic accidents. In addition, especially in student sections or bustling urban sections, such as off-hours, off-school peak hours or at night, regular traffic light settings will cause frequent waiting for car owners, and make the vehicles behind continue to accumulate, causing traffic congestion to a certain extent.

Problems solved by technology

Common traffic lights are mostly timed. The time of red, yellow and green lights is fixed. This kind of traffic lights is not safe enough. When the road is too wide, pedestrians, especially the elderly or children, often walk on the road when the road is too wide. In the middle of the road, it is easy to crash and cause traffic accidents

In addition, especially in student sections or bustling urban sections, such as off-hours, off-school peak hours or at night, regular traffic light settings will cause frequent waiting for car owners, and make the vehicles behind continue to accumulate, causing traffic congestion to a certain extent. Crowded, and in the rush hours of school and school, there will be a large flow of people crossing the road. In the case of a large flow of people, if the timed traffic light control system is used, pedestrians often walk in the middle of the road. The lights are already on, which will easily lead to traffic accidents and traffic jams
