Abstract

With the increasing speed of construction and the continuous improvement of its corresponding infrastructure, the expressway plays an increasingly important role in promoting the development of China's economy, tourism, transportation, and cultural industries. However, at present, traffic congestion in the expressway is becoming more and more frequent, which has seriously affected people's travel. In this paper, according to the congestion area of the expressway, the control method of the graded variable speed limit is proposed to realize the dynamic control of vehicle speed on the road, improving the traffic efficiency and safety. Through the analysis of the simulation results, after the implementation of hierarchical variable speed limit control, the speed change of vehicles on the road section is more gentle. The speed fluctuation is smaller, which shows that the research on the hierarchical variable speed limit control in traffic bottleneck areas can provide a theoretical basis for alleviating road congestion and reducing traffic accidents. The research is of great significance for improving traffic efficiency and safety.
