Improved traffic light control technology for passage of vehicles at crossroads of urban roads

Abstract

Provided is an improved traffic light control technology for the passage of vehicles at crossroads of urban roads. Traffic congestion at the crossroads of urban roads is a modern urban disease. The improved traffic light control technology for the passage of vehicles at road junctions of urban roads comprises a crossroad (1), longitudinal roads (I-II) and lateral roads (III-IV). The crossroad is provided with go-straight, left-turn and right-turn lane lines. A go-straight signal light (2), a right-turn signal light (5) and a left-turn non-motor vehicle signal light (6) are respectively arranged above the lane lines of each road junction of the crossroad according to the lane signs. A left-turn waiting signal area (12) is arranged at a distance of 100 meters behind each go-straight signal light. There is a left-turn waiting signal light (3) in each left-turn waiting signal area. A left-turn passing signal light is arranged on the left side of each road junction. Pedestrian signal lights(7) are respectively arranged at the four corners of the crossroad. The technical scheme is applied to the improved traffic light control technology for the passage of vehicles at crossroads of urbanroads.

Description

Technical field: [0001] The invention relates to the field of transportation, in particular to an improved traffic light control technology for vehicles passing at city road crossroads. Background technique: [0002] At present, vehicle congestion at urban road intersections is a modern urban disease and has become a worldwide problem. In order to improve congestion, overpasses, viaducts, etc. have appeared to divert traffic in all directions. This kind of facility has huge investment, and some intersection streets have already The formation cannot be demolished, especially the ancient buildings with urban characteristics cannot be demolished at all, resulting in inevitable congestion. The status quo of existing urban road intersections: one is that there is a special left-turn signal, and the left-turn traffic time accounts for more than 30% of a traffic cycle, affecting more than 30% of the traffic capacity; the other is that left-turn and straight-going vehicles are mixed...

[0002] At present, vehicle congestion at urban road intersections is a modern urban disease and has become a worldwide problem. In order to improve congestion, overpasses, viaducts, etc. have appeared to divert traffic in all directions. This kind of facility has huge investment, and some intersection streets have already The formation cannot be demolished, especially the ancient buildings with urban characteristics cannot be demolished at all, resulting in inevitable congestion

The status quo of existing urban road intersections: one is that there is a special left-turn signal, and the left-turn traffic time accounts for more than 30% of a traffic cycle, affecting more than 30% of the traffic capacity; the other is that left-turn and straight-going vehicles are mixed. Turning vehicles first decelerate or stop, and then pass through the opposite through lane, causing the vehicles in the through lane and the opposite through lane to decelerate and stop, affecting more than 30% of the traffic capacity. Cause traffic jams; when a right-turning vehicle is inserted into another straight lane at a red light, the straight vehicle has to slow down and the traffic capacity of the other straight lane is reduced. A traffic light with adjustment function and a new urban road intersection vehicle traffic scheme can solve the problem this problem
