天河机场航站楼陆侧道路的车辆行为建模

Vehicle Behavior Modeling at Landside Roads in Tianhe Airport Terminal

针对频繁停车接送乘客的航站楼陆侧道路的交通混乱拥堵等问题,研究构建基于车辆行为的精细化仿真模型,对车辆走-停-走的行为过程进行微观建模与仿真。首先分析道路环境中的车辆行为过程,分析人、车、路对车辆行为的影响;然后建立道路和车辆的微观模型;最后采用精细化停车时间的方法对车辆的停车时间进行微观仿真。仿真实验与实际交通数据进行对比,结果表明,车辆通行时间及行为变化都与实际情况相似,为车辆通行限行时间的规划与管理提供了科学的依据。

At the road of airport terminal,the environment is complex;vehicles interact with pedestrians frequently,which causes traffic congestion and increases traffic management pressure.To date,micro-simulations of traffic environments have focused on vehicle behaviors at intersections;however,little work has focused on behaviors of vehicles parking to unload or collect passengers.To solve these problems,this paper studies a microscopic simulation model based on vehicle behaviors to model and simulate the walk-stop-go behaviors of vehicles.The paper first analyzes the vehicle behavior process in the road environment,analyzes the impact of people,cars,and roads on vehicle behaviors,then establishes a microscopic model of roads and vehicles,and finally uses the refined parking time method to calculate the vehicle parking time for microsimulation.In the experiment,the travel time and trajectory of vehicles at the road of airport terminal building.By comparing with actual traffic data,the experimental results show that vehicle transit time and behavior changes are similar to the actual situation,verifying the rationality of refined modeling and helping to improve road traffic efficiency.
