Road network tide traffic flow variable guide lane control method

Abstract

The invention relates to the technical field of traffic control, and especially relates to a road network tide traffic flow variable guide lane control method. The road network tide traffic flow variable guide lane control method comprises the steps of a, monitoring a road network traffic flow in real time through the video and performing intersection modeling; b, analyzing intersection entrance traffic flow turning imbalance and a variable guide lane; c, building a variable guide lane intersection upstream vehicle smooth transition mode; and d, setting and controlling a tide congestion intersection variable guide lane in a linkage manner. According to the invention, the operating state of urban road network traffic flows is monitored online in real time by adopting unmanned aerial vehicle video, and urban road network traffic flow and intersection modeling is performed for tide congestion intersections and key road sections, so that a new mode for variable guide lane control can be realized; and the road network tide traffic flow variable guide lane control method adapts to the intersection traffic flow turning imbalance and reduces disturbance for traffic running of road sections according to an interaction relation between traffic flow dynamic requirements and traffic facility static supply.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a method for controlling a variable guiding lane of tidal traffic flow in a road network. Background technique [0002] In the late 1960s, the first attempt to open the use of variable steering lanes was made on the road from Washington to Lincoln, New Jersey. In the 1970s, variable guiding lanes were applied to bridges and tunnels in Europe, America, and Australia; in the 1980s, research was conducted on the introduction of variable guiding lanes technology into urban special-purpose roads, such as roads with high load ratios and bus lanes. 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-siz...

Problems solved by technology

In addition, due to the small distance between adjacent intersections of variable guiding lanes at intersections, the mutual influence of traffic flow between adjacent intersections is relatively large
