Stacked soft flyover system of crossroad and three-way intersection

Abstract

The invention discloses a stacked soft flyover system and relates to a stack area arranged at a crossroad and a three-way intersection. A parallel go-through control mode is adopted for stack vehicles and red and green light two-phase control without left and right turn lights is adopted at the same time, so that the waiting time of the vehicles is effectively reduced. The stacked soft flyover system disclosed by the invention belongs to the technical field of traffic control, and a reasonable stack area can be obtained by virtue of quantum chemistry calculation at the same time. Cross roads or three-way intersections in modern cities generally adopt red and green light control, but due to the conflict between left turn vehicles and straight ahead vehicles, the traffic efficiency is reduced. According to the stacked soft flyover system disclosed by the invention, a stack area is reasonably arranged on a main traffic road, and by virtue of the parallel principle, the left turn waiting time can be quickly, effectively and adaptively reduced, the traffic conflicts are reduced and any operations of left turn, right turn and the like can be realized; besides, the stack area also has an emergency area for placing vehicles having an accident. The stacked soft flyover system disclosed by the invention is suitable for each planar intersection in cities. The number of lanes can be increased or reduced according to conditions of intersections. The stacked soft flyover system uses a stack principle and a mode of changing series into parallel to improve the traffic capacity of planar traffic intersections, is suitable for designing intersection soft flyovers of major-major and major-auxiliary roads, and can be used for improving the traffic emergency transport capacity.

Description

technical field [0001] The invention relates to a stacked soft interchange system at intersections and three-forks, belonging 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 pre-set 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 control meth...
