ABSTRACT
In recent years, due to the implementation of the highway-free policy during holidays, the travel demand and traffic volume during holidays have increased significantly, and the resulting congestion problem is more serious. To better analyze and study the traffic flow characteristics of expressway hot toll stations during holidays, and put forward targeted optimization strategies to achieve the purpose of improving the efficiency of highway operation during holidays, this paper takes the toll collection data of more than 5 million lines of expressways in Jilin Province in 25 days from September to October as the research object. By using the characteristics of traffic flow on different characteristic days, this paper summarizes the characteristic data of traffic flow by statistical means and depicts the trend chart of hot toll stations based on geographic information using the digital visualization method. Based on basic data cleaning and classification analysis, a flow rate of hot toll station phase change analysis, according to the characteristic of geographic information data, and Jilin province, based on the three-dimensional map heat flow variation, the comprehensive finish holiday hot spots for highway toll station traffic flow characteristics of the impression. Based on this, the paper puts forward the optimization policy of highway holiday travel optimization.
