Advance left-hand steering and its driving method

Abstract

The invention relates to advance left-hand steering and its driving method. According to the invention, two bidirectional-lane level crossings are arranged. Four unidirectional-lane separated roads (1) are disposed at the crossroad of the two level crossings. An advance left-hand steer waiting zone (2) is arranged at the level center of the separated level crossings. Steer waiting lanes for (3) are arranged in the steer waiting zone (2). A left-turn driving signal lamp (6) is mounted over a lamppost at each exit road. When driving at the entrance roads at the traffic light, through left-and-right-hand turning traffic flows can park to wait for green lights. When facing green lights, through right-hand turning traffic flows enter the crossings. After left-hand turning traffic flows wait to enter through right-hand steering crossings for 10-15 seconds and when the left-turn driving signal lamp turns green, the left-hand turning traffic flows enter the crossings and drive into the advance left-hand steer waiting zone (2), so as to wait for through traffic flows at another level crossings drive away from the crossings at the same time. There is no intersection conflict point when through left-hand turning traffic flows are at the same phased crossing. Through the design provided by the invention, the waiting time for green lights is short when vehicles are at the entrance roads, blowdown flow rate of automobiles is minimized, and it is safe for driving.

Description

Technical field [0001] The invention relates to an advanced left-hand drive and a driving method thereof, especially at cross-shaped crossings of urban traffic roads, and the cross-shaped crossings are now converted into semi-circular crossings. There is no setting of signs for turning left and detour around the ring road, and the advanced left and its driving method in the ring road waiting area. Background technique [0002] On the current traffic roads, especially in the traffic flow organization at level crossings of urban traffic roads, the general implementation is to control the flow of vehicles with two-phase and four-phase signal lights, but if the two-phase signal lights control the flow of vehicles, it is straight to the left. Crossing conflict points occur when passing through. When the four-phase signal lights control the diversion of vehicles, the cycle of signal lights may increase accordingly, and the waiting time of vehicles waiting for the green light to pa...

Problems solved by technology

[0002] On the current traffic roads, especially in the traffic flow organization at level crossings of urban traffic roads, the general implementation is to control the flow of vehicles with two-phase and four-phase signal lights, but if the two-phase signal lights control the flow of vehicles, it is straight to the left. Crossing conflict points occur when passing through. When the four-phase signal lights control the diversion of vehicles, the cycle of signal lights may increase accordingly, and the waiting time of vehicles waiting for the green light to pass will increase accordingly, resulting in easy congestion at intersections or road sections, and vehicle exhaust emissions. There will be more and more traffic, one-way traffic is often implemented on road sections and left turns are prohibited at intersections and detours, vehicles wait for a long time for green release, the original roundabout occupies a lot of land, the speed of the vehicle is slow, mixed flow, and the waiting section of the roundabout is short , when the left turn traffic is heavy, the vehicles waiting for the green release in the waiting area of ​​the ring road to go straight to the intersection need to slow down or stop and wait and see, and there are potential safety hazards and defects
