基于MATLAB的地铁站换乘人数敏感度分析

MATLAB sensitivity analysis of subway station transfer numbers

为研究地铁枢纽站换乘人数对车辆系统运营成本的影响,建立了车辆系统运营成本模型,基于MATLAB分别分析了在换乘乘客的步行时间小于、等于和大于松弛时间时,换乘人数对换乘乘客的费用、车辆运行费用及车内乘客费用的影响。结果表明:模型可有效反映换乘乘客步行时间与松弛时间不同关系时换乘人数对车辆系统运行费用的影响。

In order to study the influence of passenger number of transfer at the subway pivotal station on the operating cost of vehicle system, vehicle system operation cost model is established. The influence of the transfer number on the cost of the transfer passenger, the running cost of the vehicle and the cost of the passenger in the vehicle is analyzed when the walking time of the transfer passenger is less than, equal to and larger than the relaxation time. The results show that the model can effectively reflect the influence of the number of passengers on the running cost of the vehicles system when the passenger’s walking time is different from the relaxation time.
