Problems solved by technology

These intersections have a long period, each phase lasts 30-50 seconds, and the traffic capacity is low
The main reason for these shortcomings is that there are many conflict points for left-turning vehicles, blocking straight-going vehicles and blocking exit lanes, and it takes a lot of cycle time to release left-turning vehicles

Embodiment 1

[0110] like figure 2 As shown, it is a batch variable area entrance and exit. Outside the exit lane 13, that is, opposite to the exit lane 13 of the left-turn waiting area 1, a reverse traffic zone 2 is set up, and the reverse traffic zone 2 is ahead of the left-turn waiting zone 1 by a longitudinal distance.

[0111] The central isolation between the left-turn waiting area 1 and the exit, and the isolation zone 16 between the exit lane 13 and the reverse traffic area 2 are all indicated by dashed lines.

[0112] Set stop line 8 on the exit lane 13 between the front part of the left-turn waiting area 1 and the front part of the retrograde area 2, and corresponding exit lights, the exit lights are common traffic lights.

[0113] Retrograde zone 2 is equipped with light poles, with curved long arms on the light poles. The long arms extend into the sky above the exit, and row lights are installed on the long arms, so that the row lights are above the exit.

[0114] A row of la...

Embodiment 2

[0123] A batch variable area entrance and exit, the others are the same as those in Embodiment 1, the difference is that:

[0124] There is only one lane in left turn waiting area 1 and reverse traffic area 2 respectively.

[0125] The signal lights 25 all illuminate the left-turn waiting area 1 obliquely backward, and the angle β formed by the boundary lines of the light range is 22 degrees. The direction of the beam centerlines of each signal lamp 25 is parallel, and the angle γ between the beam centerline and the longitudinal direction of the entrance and exit is 45 degrees, and each lamp faces the left-turn waiting area 1 .

[0126] t1 is the first second, the green duration c1 of each light in the row of lights is 3 seconds, the exit light turns green time t2 is the 6th second, and the speed v is 15m / s.

[0127] The vehicle travels from the left-turn waiting area 1 to the left front and enters the reverse traffic area 2. During this process, it travels an average of 25 m...

Embodiment 3

[0133] The entrance and exit of the batch variable area are applied to the left turntable. The left turntable is single-phase controlled, and the cycle is 36 seconds. The red duration of the exit lights of each entrance and exit is 6 seconds, which accounts for 16.7% of the period.

[0134] Batch variable zone entrances and exits are applied to intersections, which are controlled by two phases, and the cycle is 70 seconds. The red duration of the exit lights of each entrance and exit is 8 seconds, which accounts for 11.4% of the period.

Abstract

The invention relates to the traffic field, in particular to a batched variable-region junction and application thereof. A reversing region is arranged on the outside of an exit lane of an exit of thebatched variable-region junction, and is connected with a left turning lane of a next junction. A bank light is arranged in the left front direction of a left turning waiting region, and under guidance of a green bright belt of the bank light, vehicles of the left turning waiting region independently run to the left front direction, and then run into the reversing region to leave away from the exit lane so as to relieve and avoid blockage to the exit lane as much as possible. By the method, blockage to the outlet lane in the whole cycle is quite less. If the junction is used at a crossroad, two-phase control can be implemented. If the junction is used at a three-way intersection, single-phase control can be implemented. Various junctions of a turn plate use the batched variable-region junctions, then the turn plate becomes a leftward turn plate, and the vehicles leftwards turn to enter the turn plate. An overpass bridge uses one layer of the left turn plate, or uses one layer of the left turn plate and one layer of a common turn plate, and thus, interweaving of the turn plate can be relieved. By application of the batched variable-region junction, the traffic capacity of urban junctions is greatly enhanced, and delay is relieved.

Description

technical field [0001] The invention relates to the traffic field, relates to intersection structure, phase control, and interchange design, in particular to a batch-variable area intersection and its application. Background technique [0002] Most of the current intersections use three-phase control at three-way intersections, four-phase control at intersections, and more complex phases at multi-fork intersections. The left-turning lanes at the intersection are all within the intersection area, intersecting with the through lane, and each left-turning lane is intersecting, thus forming a conflict. The cycle of these intersections is long, each phase lasts 30-50 seconds, and the traffic capacity is low. The main cause of these disadvantages is that there are many conflict points of left-turning vehicles, blocking straight-going vehicles and blocking exit lanes, and a lot of cycle time must be spent to release left-turning vehicles. [0003] Intersections, also known as int...
