摘要
把步行时间、候车时间、乘车时间、乘车费用等影响公交出行的因素,通过数学建模的方法得到其与动态公交信息间的函数关系。利用参数标定方法建立起公交阻抗的综合函数关系,借助数学方法,将时间与费用这2种阻抗进行量纲的统一。进而实现了公交阻抗与其他交通方式阻抗之间的可比。将模型应用于具体的实例中,证明了该模型的有效性。
Through mathematical modeling, this paper develops a function to link the factors influencing transit ridership, including walking time, waiting tirae, riding time, cost with dynamic public transit information. Through parameter calibration, a function for transit impedance is developed and a mathematical model is used to unify the following two impedances., time and cost. This basically makes it possible to compare public transit impedance with those from other transportation modes . Finally, the model is applied to a case study and its effectiveness is proved.
