Embodiment 1

[0017] Embodiment 1: Taking the crossroad traffic regulation area as an example

[0018] A parallel traffic control method for stacking areas at crossroads. Stacking areas are set on the main roads L2 and L4, and auxiliary stacking areas are set on L1 and L3. Through the principle of parallelism, the waiting time for left turns can be reduced quickly, effectively and adaptively , reduce traffic conflicts, and can realize arbitrary left turn, right turn, U-turn, etc. The spare areas (E, F) formed between the circular areas can be used to set up emergency areas, and can also be used to set up flower beds and plant urban greening plants to beautify the environment.

[0019] The specific implementation method in this embodiment is that when passing in the direction of L1L3 and L3L1, the vehicles of L4L2 stop at R4, the vehicles of L2L4 stop at R2, L1 can reach L3 through A and B curves, and L3 can reach through C and D curves L1. At the same time, vehicles in the direction of L1...

Embodiment 2

[0021] Embodiment 2: Taking the traffic rules at the three-fork intersection as an example

[0022] A parallel traffic control method for stacked areas at crossroads. Stacked areas are set on the main roads L3 and L2. Through the parallel principle, it can quickly, effectively and adaptively reduce the waiting time for left turns and reduce traffic conflicts. It can be used in the stacked areas. Any left turn, right turn, U-turn, etc., and an emergency zone (L3 left-turn lane in the area between P4 and P2) is set up to accommodate vehicles in accidents.

[0023] The specific implementation method in this embodiment is that the vehicle turning right from the main channel L2 to the channel L1 can directly turn right without waiting; the vehicle that needs to turn right from L1 and enter L3 can directly turn right in a single lane without waiting. When L1L2, L3L1 direction, L2L3, L3L2 straight vehicles stop and wait at traffic lights P2, P3; P1 green light, L1L2 smoothly turn lef...

Abstract

The invention relates to a parallel traffic control mode based on crossing stack areas and belongs to the technical field of traffic control. According to the situation that the principal contradiction of urban traffic is concentrated on that left turning vehicles and straight-going vehicles conflict, so that the split-phase promotion of a whole passage is caused, and the traffic efficiency is reduced, the stack areas are reasonably arranged on a main path, the left turning waiting time can be rapidly and effectively shortened in a self-adapting manner through the parallel principle, traffic flow conflicts are reduced, and the vehicles can arbitrarily turn left, turn right, turn around and the like. Moreover, emergency areas are also arranged, and can be used for setting vehicles in accident. The parallel traffic control mode based on the crossing stack areas provided by the invention is suitable for all urban grade crossings. The set number of lane can be increased or reduced according to crossing conditions. According to the parallel traffic control mode based on the crossing stack areas provided by the invention, by utilizing the stack principle and a deserializing mode, the traffic capacity of traffic grade crossings is improved. The parallel traffic control mode based on the crossing stack areas is suitable for crossing soft fly-over design of primary and secondary roads, so that the traffic emergency transport capacity is improved.

Description

technical field [0001] The invention relates to a parallel traffic control method in a stacking area at an intersection, and belongs to the technical field of traffic control. Background technique [0002] At present, urban traffic control is a very difficult task. Generally speaking, urban traffic control adopts various methods: [0003] (1) Timing control; traffic control adopts traffic signal light control, and operates according to the preset timing plan, and the timing is based on the historical data of traffic volume. It is called single-period timing control if only one timing scheme is used in one day, and multi-period timing control is called multi-period timing control if different timing schemes are used in different periods of the day. A method for determining its optimal timing based on historical traffic data. The most commonly used signal timing methods are: Wilbert method, critical lane method, stop line method, and conflict point method. The timing contro...
