Reversible short lane signal control method based on intersection vehicle in-turn release

Abstract

The invention discloses a reversible short lane signal control method based on intersection vehicle in-turn release. According to the method, four inlets in the east, south, west and north at an intersection are respectively provided with one segment of reversible short lane by utilizing opposite lanes, four outlet lanes are respectively provided one set of reversible short lane indicating lamps, right sides of stop lines of the four inlets are respectively provided with one set of left turning pre-signal lamps, main signal lamps at the intersection employ a clockwise or anticlockwise in-turn release four-phase mode for all vehicles at each inlet lane, phase difference between the main signal lamps and the left turning pre-signal lamps is set, and the reversible short lane indicating lamps and the left turning pre-signal lamps realize simultaneous conversion; phase difference between main signals and left turning pre-signals is coordinated, public period duration and green light distribution time are calculated, conflicts between a left turning traffic flow and an outlet lane traffic flow are controlled in the time aspect, left turning traffic flow jam caused by improper time distribution is avoided, inlet and outlet land resources are fully utilized, the lane number of inlet lanes is enhanced, and passing capability of the intersection is improved.

Description

technical field [0001] The invention belongs to the field of urban road traffic control, and relates to a signal control method for a left-turn motor vehicle passing through a reverse lane at a level intersection entrance. Background technique [0002] With the rapid development of the urban economy, the limited urban road land can no longer meet the increasing car ownership, and the intersection congestion is becoming more and more frequent, resulting in multiple parking at the intersection, reduced traffic quality at the intersection, noise pollution, and vehicle exhaust emissions. Various traffic problems such as traffic increase. There are often fewer vehicles on the exit road at the intersection, and the queue of vehicles on the entrance road is too long, resulting in multiple parking situations. How to design an intersection that can not only preserve the existing buildings without a large number of demolition and reconstruction projects but also meet the increasing t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the traffic demand cannot be satisfied due to the limited space at the intersection, and propose a reversible short lane signal control method based on the vehicle wheel release, setting the direction reversible short lane, and combining the release mode of the vehicle wheel Left-turning vehicles can safely use reversible short lanes to improve traffic capacity and lane use efficiency at signalized intersections
