Dynamic Control Design of Tidal Lanes of Intelligent Highway Toll Station: A Case Study of Xiongan New Area, China

With tidal traffic becoming an important feature of urban transportation, the impact of tidal lanes on traffic flow is a research topic for many scholars. This paper explores the setting scheme of tidal lanes at toll stations based on the conditions and rules for setting up tidal lanes on urban roads. A highway tidal toll station model is established based on VISSIM. The traffic flow characteristics are simulated when the main traffic flow directions in tidal traffic are located at the exit and entrance of the toll station, respectively. We use a tidal coefficient of 0.7 as an example to analyze the impact of the switching ratio of tidal lanes at toll stations on the traffic volume in the exit and entrance directions under different traffic flow states. We determine the optimal number of tidal lanes to open through analysis of traffic growth rate and total traffic volume changes at toll stations, and propose an opening model for tidal lanes at toll stations under different tidal traffic flow states. In addition, we take the Jingxiong Highway in China as an example to design the traffic organization of the tidal lane, which provides reference for the control of tidal toll stations.
