Embodiment Construction

[0034] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] The present embodiment applies the control method of the present invention for turning left using the through lane on the right side of the intersection based on the following conditions.

[0036] The conditions are as follows:

[0037] (1) Facing the intersection of 3rd, 4th and 5th roads, in order to meet the needs of small cars to complete a U-turn smoothly at one time, in the absence of a central divider, plan no less than 3 lanes for each exit; In the case of a median, the number of exit lanes shall be based on the width of the median;

[0038] (2) The signal phase of each intersection is two phases, and the phase structure design method adopts a known method;

[0039] (3) There are not many motor vehicles turning left.

[0040] This embodiment provides a control method for turning left using the right through lan...

Abstract

The invention provides a control method for turning left by using the right straight lane of the intersection, including: setting the operation rules for turning left by using the right entrance straight lane; determining the length of the left-turn waiting area; calculating signal timing, each Imported straight-going vehicles and right-turning vehicles are separately controlled, the green lights of straight-going vehicles and left-turning vehicles are turned on at the same time, and the yellow lights of right-turning vehicles are turned on in advance; the position of the left-turning far-leading U-turn of each imported lane is determined. In the present invention, the left-turn waiting area is placed in front of the straight-going vehicle, which reduces the detour distance of the left-turn vehicle and the interference to the straight-going vehicle when turning around. Use two-phase control, place the through lane on the left side of the road, and set up a left-turn waiting area near the intersection of the through lane at this time. The original right-hand through lane is a left-turning vehicle turning right and entering a left-turn waiting area. Vehicles entering the left-turn waiting area can turn left by going straight, so as to improve the traffic efficiency of intersections with a small number of left-turn vehicles.

Description

technical field [0001] The invention belongs to the technical field of traffic control, in particular to a control method for turning left by using the right straight lane at an intersection. Background technique [0002] At present, the traffic efficiency of the intersection is an important factor to determine whether the urban traffic is smooth, and whether motor vehicles can pass the intersection smoothly has attracted people's attention. When managing and controlling intersections, the management and control of left-turn motor vehicles is a difficult problem to solve. When there are left-turning vehicles at the intersection, although the number of left-turning vehicles has met the minimum requirements for setting the left-turning special phase at this time, setting the left-turning special phase at this time will reduce the utilization rate of the signal cycle; on the contrary, if you do not set The special phase for turning left cannot avoid the conflict point between ...
