Modeling of Passenger Waiting Time in Intermodal Station with Constrained Capacity on Intercity Transit

Abstract: This paper aims to develop a mathematical model to analyze the passenger waiting time in an intermodal station in which intercity transit system served with feeder buses. Passengers are categorized into two groups, named scheduled and random, respectively. The analytic model is developed for quantifying the relationships of passenger waiting time to reliability of feeder bus services and capacity of intercity transit. The numerical results identify that mean waiting time of intercity transit passengers is greater than half of the intercity transit headway, with the condition that feeder service is provided with poor reliability; and on the contrary, mean waiting time will be less than half of the intercity transit headway. Moreover, to avoid long waiting time, headway deviation of feeder buses should be less than 3.5 minutes. In terms of intercity transit capacity, it is suggested that at least 80 % of total arrival passengers should be satisfied.
