Flat intersection left turn entrance lane removing method and method for driving on flat intersection left turn entrance lane

Abstract

The invention relates to a flat intersection left turn entrance lane removing method and a method for driving on a flat intersection left turn entrance lane. A flat intersection comprises two bidirectional lane crossed roads, a right turn lane and a left turn lane. The left turn lane comprises a left turn entrance lane, a left turn waiting lane (1), a crossing lane entrance (2), an intersection signal light (4), a lane area (6), a lane area signal light (4) and an oblique signal light (5), wherein the left turn entrance lane which used to be arranged on the left side of an entrance lane at the intersection now is removed to the right side of an exit lane (8); the left turn waiting lane (1), the crossing lane entrance (2) and the intersection signal light (4) are arranged in a rear section far from an original left turn entrance lane; and the lane area (6), the lane area signal light (4) and the oblique signal light (5) are arranged in the exit lane (8). Vehicles to turn left run to the left turn waiting lane (1) from a running lane (14) to wait for a green light and then run through the crossing lane entrance (2) and the lane area (6) to a left turn entrance lane (7) on the right side of the exit lane to wait for turning. The design adopted in the invention eliminates a conflict point which occurs when the vehicles to turn left and vehicles to go straightly run together, shortens time limit periods of red and green light at the intersection, and relieves traffic jam and disturbance at the flat intersection.

Description

Technical field [0001] The invention relates to a level crossing left-turn entrance migration and a driving method thereof, in particular to a level crossing left-turn entrance migration and a driving method thereof which can alleviate traffic jams and time-consuming traffic at urban cross-shaped and T-shaped level crossings. Background technique: [0002] At present, indirect left turns are adopted at cross-shaped and T-shaped level crossings. If there are traffic measures such as setting left in advance and far-leading intersections and circles, the above-mentioned setting left in advance is only to make more turns in advance within the time limit set for left turns. A few vehicles, the above-mentioned far-leading intersection is to lead the vehicle that is going to turn left to a gap far away from the intersection dividing line, turn around and then return to the intersection. This kind of left-turning vehicle not only needs to drive one or two hundred meters in vain. In ...

[0002] At present, indirect left turns are adopted at cross-shaped and T-shaped level crossings. If there are traffic measures such as setting left in advance and far-leading intersections and circles, the above-mentioned setting left in advance is only to make more turns in advance within the time limit set for left turns. A few vehicles, the above-mentioned far-leading intersection is to lead the vehicle that is going to turn left to a gap far away from the intersection dividing line, turn around and then return to the intersection. This kind of left-turning vehicle not only needs to drive one or two hundred meters in vain. In addition, the left-turning vehicles have to go through merging, diverging, U-turning, and then merging and diverting to make a left turn. It occupies a lot of land, and when the traffic flow is heavy, the congestion at this intersection cannot be really alleviated due to the short waiting lane and the slow traffic flow, and it is often considered to build an overpass or viaduct to completely solve the problem
