基于流体力学下潮汐车流收费站的调度研究

Research on the scheduling of tidal traffic toll station based on fluid mechanics

在高速路上,其道路交通容量受限于收费站的数量,近年来随着节日自驾出行的增多,道路两侧经常会出现高低峰车流量。文章针对车辆的潮汐现象,运用流体力学模拟理论和排队论建立了车辆通过收费广场的耗时模型,求解不同车流量下,收费广场所需开放的收费亭数量,通过动态调整收费亭的收费朝向,能够有效缓解由潮汐车流所导致的拥堵状况。

On highways,the road traffic capacity is limited by the number of toll stations.In recent years,with the increase in holiday self-driving travel,high and low peak traffic flows often appear on both sides of the road.Based on the tidal phenomenon of vehicles,the fluid dynamics simulation theory and queuing theory are used to establish the time-consuming model of vehicles passing through the toll plaza,to solve the number of toll booths required for toll plazas under different traffic flows,and to adjust the toll direction of the toll booths dynamically.It can effectively alleviate the congestion caused by tidal traffic.
