Embodiment 11

[0044] The three-fork intersection is formed by the intersection of A, B, and C roads. A, B are straight roads, and C road is a turning road. Vehicles on road B turn left to reach road C, and vehicles on road C turn left to reach road A. Vehicles traveling from road B to road C need to cross the A to B side of the A / B road. A and B are the main traffic, respectively two-way 4-lane; C road is a secondary road, two-way 2-lane. This is the most common three-fork intersection, also known as a T-junction.

[0045] A road establishes left-turn lane 3, and described C road establishes the waiting area 5 leading to A road as a left-turn waiting area, and the exit of the left-turn waiting area is connected to A road left-turn lane.

[0046] like figure 1 As shown, Road B is the entrance and exit for changing lanes in batches. The waiting area 1 leading to Road C is set at the entrance of Road B as a left-turn waiting area. Turning lane 3, the reverse lane of Road B connects to the l...

Embodiment 12

[0049] A and C are straight roads, vehicles on road A turn left to reach road B, and vehicles on road B turn left to reach road C, such as image 3 As shown, A and B are the main traffic, which is an intersection where the main traffic turns.

[0050] Road B adopts entrances and exits that change lanes in batches, and the entrance of Road B is set up to waiting area 1 leading to Road C. This waiting area is a left-turn waiting area. There is a reverse lane 2 outside the exit lane 4 of Road B, and a left-turn lane 3 is set at the front end of the entrance of Road C. The reverse lane of Road B connects with the left-turn lane 3 of Road C, and then connects to the exit lane 4 of Road C. Road C is provided with a waiting area 5 leading to Road A and a signal light leading to Road A. The waiting area is a straight waiting area, and the waiting area is located outside the exit lane 4 of Road C.

[0051] The three-fork intersection is controlled by two phases. The first phase is the...

Embodiment 13

[0054] Roads A, B, and C intersect at the three-fork intersection. Vehicles on road C turn left and arrive at road A, and vehicles on road A turn left and then arrive at road B. B and C are straight roads, such as Figure 4 As shown, A and B are the main traffic, and B and C form the straight road, which is a turning intersection of the main traffic.

[0055] Road B is the entrance and exit for changing lanes in batches. The waiting area 1 leading to Road C is set at the entrance of Road B and is a straight waiting area. The waiting area 5 leading to the A road in the C road is a left-turn waiting area, and the left-turn waiting area is located on the outside of the exit lane. There is a left-turn lane at the entrance of Road C, and the reverse lane of Road B connects to the left-turn lane of Road C.

[0056] In the second phase, the vehicles in the straight waiting area of ​​Road B enter the reverse lane 2 by changing lanes in batches, and then enter the exit lane 4 of Road...

Abstract

The invention discloses a three-way intersection adopting a batch lane changing method and a control method thereof. An existing three-way intersection is characterized by having no phase control or performing three-phase control, and having the problems of low traffic capability and large delay. The novel three-way intersection is characterized in that the main traffic direction from an entranceto a secondary road needs to pass through a lane in the other direction of the main traffic, and the entrance at this direction adopts the batch lane changing method. According to the novel three-wayintersection, by means of the batch lane changing method, the time of one phase can be reduced, two-phase control can be adopted in the three-way intersection, the period is short, the delay is small,and the traffic capacity is large.

Description

technical field [0001] The invention belongs to the traffic field, and in particular relates to the intersection structure and phase control of a three-way intersection. Background technique [0002] Three-way intersections are very common in the intersections of urban roads, and three-way intersections are an important part of urban roads. Except for a few Y-shaped intersections, there are two directions of left-turning traffic at the three-fork intersection. The current three-way intersections are all controlled by two-phase or three-phase. The two-phase control means that the main traffic is terminated, and left turns in two directions are carried out at the same time, and there are conflict points. This method is only suitable for small three-way intersections. For a three-phase control intersection, the three phases are the main traffic conduction phase, the left-turn phase in the first direction, and the left-turn phase in the second direction. There is no conflict p...
