基于可接受间隙理论的机场出发层车道边容量评估

摘要

首先分析了机场航站楼陆侧出发层车道边平面布局模式，研究了车道边交通流特性，然后利用可接受间隙理论建立单一车型运行下的车道边容量模型，并分别计算混合车流和行人穿行对车道边容量的影响，得出车道边不同平面布局模式下的容量计算公式。最后通过实际数据观测，以天津机场陆侧出发层车道边为案例进行研究，并运用VISSIM仿真软件进行验证分析。结果表明，该容量模型能够有效评估机场出发层车道边容量，为机场评估和设计人员提供科学依据。%First the layout mode and traffic flow characteristics of departure curbside parking of transportation in airport landside were analyzed .Then the gap acceptance theory was used to establish capacity model of curbside with single motorcycle type , and calculate the influences from mixed motor vehicles flow and pedestrians passing through separately , and work out the capacity calculation formula of various layout mode curbside under the influ-ences.At last, with factual observation data, take Tianjin airport departure curbside as a case study and analysis of test results using VISSIM simulation software .Results show that the model can effectively assess the capacity of air-port curbside , can provide a scientific basis for evaluation and design to the airport personnel .
