City crossroad vehicle traffic improved technique

Abstract

The improving technique of vehicle traffic on urban crossroad. The present status of urban crossroad is: one is special left-hand turning signal with its left turning time accounting 30% of a traffic cycle and above 30% influence of traffic capacity. The other one is commix traffic. Left-hand turning vehicles decelerate and pack firstly and traverse subtend straight lane. It causes decelerating and parking of vehicles on straight lane, which reduces above 30% traffic capacity and leads traffic jamming. The invention contains: (1) Longitudinal and lateral roads. Set straight signal lamps on each crossing of the crossroads1. (2) Right-hand turning signal lamp5 and left-hand turning non-automobile signal lamp6. Set left-hand turning signal lamp3 behind 2 about 60m and left-hand turning passing signal lamp4 on the left side of each road. Set pedestrian signal lamp 7, 8, 9 on the four corners of 1. The invention is applied for urban crossroads.

Description

Technical field: [0001] The invention relates to a technology for improving vehicle traffic at urban road crossings by resetting signals and marking lines at urban road crossings. 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 inserts into another through lane at a red light, the through vehicle has to slow down and the capacity of the other through lane is reduced
