Control method for variable lane based on holographic road network tide traffic flow

Abstract

The invention discloses a control method for a variable lane based on a holographic road network tide traffic flow. The method comprises the following steps: 1) modeling for an intersection according to the real-time condition of the traffic flow fed by a holographic road network; 2) analyzing the steering balance degree of the traffic flow at intersection inlet and the use ratio of the variable guiding lane; 3) establishing a smooth transition mode of the vehicles upstream the variable guiding lane intersection; and 4) linking and controlling the guidance of the variable lane at the tide jam intersection. According to the invention, the adjustment for the unbalance of the traffic flow direction on the road section is taken as the objective; the effective control on the unbalance of the traffic flow at intersection inlet and the variable guiding lane can be realized; the meso/micro-level traffic resource space-time coordinated management for the traffic nodes and key sections of the road network is put forward; the smooth transition mode of the upstream vehicles at the variable guiding lane intersection is established; the setting and induce control method for the variable lane at the tide jam intersection is realized; the practical application level for feeding-side structural reformation of the urban road traffic resource is promoted.

Description

technical field [0001] The invention relates to the technical field of traffic control and management, in particular to a method for controlling variable lanes based on holographic road network tidal traffic flow, which can realize a new control mode of variable guiding lanes for tidal congestion intersections and key road sections. Background technique [0002] In the 21st century, the application hotspots of variable guiding lane technology mainly focus on emergency evacuation of traffic flow under extreme weather conditions. In 2004, a survey on the implementation of variable steerable lanes in 49 states in the United States found that almost all large cities and some small and medium-sized cities have applied variable steerable lane technology. [0003] A variable steering lane means that there are more than one lane direction after entering the lane, and some intersections allow right turn and straight travel (that is, right turn and straight travel merge into one lane)...
