Main road priority control intersection traffic simulation method and device

Abstract

The invention relates to a main road priority control intersection traffic simulation method and device, and the method comprises the steps: determining secondary road vehicles in an intersection and a plurality of interacting main road traffic flows as research objects based on a special traffic operation scene of a main road priority control-free intersection, and by predicting the driving tracks of conflicting interaction vehicles through simulation deduction, secondary road vehicles can make more efficient passing decisions from numerous deduced passing schemes, simulated passing of traffic flow organizations at the non-signal-control intersection is achieved, the problem of vehicle operation simulation when multiple conflicting traffic flows conflict and interleave is comprehensively considered, the secondary road vehicles serve as research targets, a dynamic model is combined to analyze passing decisions of traffic flows passing through multiple main roads, a decision scheme and a simulation result reflect traffic flow organizations in the non-signal-control intersection more truly and comprehensively, the vehicle passing efficiency of the non-signal-control intersection is greatly improved, the road traffic capacity is improved, and a scientific and reasonable decision-making scheme and decision-making basis are provided for reducing delay.

Description

technical field [0001] The invention relates to a traffic simulation method and device at a main road priority control intersection, and belongs to the technical field of traffic simulation. Background technique [0002] In the 21st century, economic development has brought about a rapid increase in the number of motor vehicles, and the pressure on the urban road network is gradually increasing. As an important node of the urban road network, the improvement of its traffic efficiency has a significant impact on the transportation capacity of the urban road network. . The unsignalized intersection with priority on the main road has the characteristics of clear classification of road rights, uneven distribution of traffic flow, and overall sparse traffic flow. Compared with intersections controlled by signal lights, the traffic organization is more complicated, and the scene of vehicles passing through is more diverse. However, in China, the management norms for unsignalized ...

Problems solved by technology

Existing research also lacks the in-depth combination of simulation technology to realize the management and control of unsigned control intersections, and the organization and arrangement of traffic flow is more concentrated on the algorithm and methodology level for theoretical research
