航站楼车道边容量评估与优化

Capacity assessment and optimization of terminal curbside

为解决繁忙机场航站楼车道边日趋严重的拥堵状况,在借鉴单车道停车模型和容量计算公式的基础上,充分考虑内外车道边的相互影响推导出了双车道容量的计算评估公式.同时为提高车道边容量,提出了利用快速通道对双车道容量进行优化,通过建立模型和数学推导,得出了双车道容量最大时的快速通道数的计算公式.最后采用ServiceModel建立了有快速通道的双车道边容量仿真系统,并通过大量仿真试验与模型计算结果进行了比较验证,表明增加快速通道确实可以有效增加双车道容量.

Aimed at the severe congestion of terminal curbside, using the experience of parking model and capacity evaluation of single-way curbside, a capacity formula of double-way curbside with the consideration of the interrelationship of inside and outside curbside was set up. To enhance the curbside capacity, the taxi way was introduced to optimize the two-way curbside capacity. By setting up model and mathematical derivation, the formula to calculate the number of taxi way for capacity maximization of double-way curbside was educed. Using ServiceModel software, a simulation system for the capacity evaluation of double-way curbside was established. By comparing and validating the model results with lots of simulation results, it is indicated that taxi way can enhance the capacity of double-way curbside effectively.
