Crossroad traffic control system and control method thereof

Abstract

The invention belongs to the technology of highway traffic, and discloses a crossroad traffic control system and a control method thereof. The crossroad traffic control system comprises a timely traffic light control module and a tidal lane control module. The timely traffic light control module comprises a plurality of timing devices and traffic lights, wherein the timing devices are installed on through lanes and left-turn lanes in all vehicle directions of a traffic light crossroad respectively. The tidal lane control module comprises a plurality of counting devices and indicator lights L, wherein the counting devices are installed on one-way whole lanes respectively, and the indicator lights L are installed in dotted line road surfaces on the two sides close to lane separation solid lines respectively. According to the crossroad traffic control system and the control method thereof, the vehicle flow of each lane is detected through the timely traffic light control module to automatically adjust the traffic light time, so that the traffic flow of the crossroad reaches the optimum level; meanwhile, the proportion of vehicles in two road directions is detected through the tidal lane control module to control on-off of the indicator lights to form tidal lanes, so that the problem of traffic jam is relieved, and convenience is brought to passersby and managers.

Description

technical field [0001] The invention belongs to the field of traffic communication and control of highway traffic technology, and in particular relates to a traffic control system and a control method at an intersection. Background technique [0002] Designing traffic light devices at city crossroads is an important means to relieve traffic pressure, avoid traffic accidents and increase traffic rate. With the continuous advancement of the urbanization process in our country, the scale of the city is gradually expanding, and the number of intersections in the city is also increasing, so that passers-by encounter more traffic lights. [0003] At present, the traffic light management mechanism of most intersections is to add the estimated traffic flow on the basis of the statistical traffic flow, and artificially set the length of the red light and green light time on each lane. The original intention of this setting is to meet the maximum traffic flow. Resource allocation for...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the deficiencies in the prior art, and provide a kind of intersection traffic control system and its control method, through the size of the traffic flow of each lane to automatically adjust the length of traffic lights, so that the traffic volume of the intersection reaches The largest and the best; at the same time, by detecting the switch of the proportional control indicator light of the vehicle in the two directions of the road, a tidal lane is formed to alleviate the problem of traffic jam and bring convenience to passers-by and managers
