摘要
航站楼车道边作为机场地面交通的重要组成部分,表现出不同于普通道路和停车场的静态和动态交通特征。本文设计针对航站楼前交通特征的数据采集方法,提取期望速度、车辆加减速度、停车时间、停车间距作为反映航站楼前交通状况的重要参数并对其分布特征进行标定。最后以首都机场T3航站楼为例,利用VISSIM建立航站楼出发层车道边的仿真平台,同时结合实测数据对参数分布特征进行标定。仿真结果表明参数标定后仿真精度明显提高,误差均控制在10%以内,仿真结果合理。
As an important part of airport ground transportation, terminal curbside has both static and dynamic traffic cha- racteristics. The data collecting method aiming at traffic characteristics of airport terminal curbside is designed. Four parameters including desired speed, acceleration, dwelling time and standstill distance are extracted to re- flect the traffic characteristics at airport terminal curbside. Then, the parameter calibrating approach is proposed and a case study is conducted in T3 terminal at Beijing Capital International Airport. VISSIM is used to develop the simulation platform for airport terminal curbside traffic and the distribution characteristics is calibrated by using field data. Results indicate that after calibration the simulation accuracy is improved significantly and the errors are controlled within 10%.
