specific Embodiment approach 1

[0026] Specific implementation mode 1. Combination figure 1 , figure 2 and image 3 This embodiment will be described. A method for crossing a parallel-flow intersection with a left-turn hook-shaped turn for non-motorized vehicles described in this embodiment includes traffic geometric design and signal control; the traffic geometric design is specifically:

[0027] For each entrance of a parallel-flow intersection, a left-turn non-motor vehicle waiting area shall be set at the non-motor vehicle lane at the intersection at the front end of the through lane of the entrance, and on the side close to the center of the main signalized intersection;

[0028] Taking the west entrance as an example, the direction of the entrance refers to the direction of driving from the west side to the main signal intersection, and the straight lane of motor vehicles at the west entrance is figure 1 G in ; the definition of other entrances is the same; the non-motorized vehicle lane at the int...

specific Embodiment approach 2

[0039]Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the first stage and the last phase of the east-west straight motor vehicle, north-south left-turn motor vehicle, and east-west non-motor vehicle travel to the east-west entrance and turn left The second phase release of the left-turning non-motorized vehicles on the non-motorized vehicle waiting area; the first phase and the previous phase of the north-south straight-going motor vehicle, the east-west left-turning motor vehicle, and the north-south left-turning non-motorized vehicle travel to the north-south entrance The second phase release of left-turning non-motorized vehicles on the left-turning non-motorized vehicle waiting area; the specific process is as follows:

[0040] When the main signal turns north and south and turns left, the green light of the motor vehicle phase turns on:

[0041] Left-turn non-motorized vehicles at the west entrance travel from the starting p...

specific Embodiment approach 3

[0052] Specific embodiment three: the difference between this embodiment and specific embodiment two is that the capacity of the left-turn bicycle waiting area satisfies the following conditions:

[0053]

[0054] In the formula: N max is the number of non-motor vehicles that can be accommodated in the left-turn non-motor vehicle waiting area, and the unit is vehicle; μ is the fluctuation coefficient of non-motor vehicle flow; C is the signal period length, and the unit is s; is the traffic demand of non-motorized vehicles turning left, and the unit is vehicle / s.

Abstract

The invention discloses a hook-shaped turning crossing method and system for left-turn non-motor vehicles at a parallel flow intersection, and belongs to the field of traffic engineering. The method solves the problem that in an existing parallel flow intersection, left-turning non-motor vehicles and straight-going motor vehicles interfere with each other, and the operation efficiency of the parallel flow intersection is affected. According to the invention, the geometric layout of the parallel flow intersection is redesigned, and the left-turn non-motor vehicle waiting area is arranged at the intersection non-motor vehicle lane at the front end of the entrance straight lane and on one side close to the center of the main signal intersection, so that the left-turn non-motor vehicles are prevented from conflicting with straight motor vehicles through hook-shaped turning; corresponding traffic organization and signal control schemes are given, the operation efficiency of the parallel flow intersection is guaranteed, the design of the parallel flow intersection better conforms to the traffic application scene of China, popularization and application of the parallel flow intersection are promoted, and a new thought is provided for solving urban intersection congestion. The method can be applied to the field of traffic engineering.

Description

technical field [0001] The invention belongs to the field of traffic engineering, and in particular relates to a method and a system for crossing a parallel-flow intersection with a left-turn non-motorized vehicle hook-shaped turn. Background technique [0002] As a novel solution to urban traffic congestion control, unconventional intersections have the advantages of reducing the number of phases, increasing capacity, reducing delays, and shortening cycle time. At present, some unconventional intersections have been field-applied in many cities in my country. The practical application effect is good. [0003] Parallel flow intersections are a type of unconventional intersections. Compared with conventional intersections, they can theoretically double the capacity and effectively alleviate traffic congestion at urban intersections. Patent CN109615893A proposes a parallel flow intersection with left-turn and right-turning. The entrance left-turn lane is placed outside the ent...
