The passengers' transfer zone in the transit centers is the interface among various transportation modes, where passengers transfer from one mode to another. The Transit Cooperative Research Program (TCRP)-Report 165 presents the capacity analysis technique for the passengers' transfer zone in the transit centers. However, the TCRP-Report 165 procedure is based on the fixed values of passengers' arrival flow and service time of facilities, which do not depict the real scenario. To aid the designers of transit centers as well as to capture the randomness in the arrival flow and service time, a discrete-event simulation (DES) framework based on the PH-distributed random variates is developed. The DES framework represents the passengers flow in the transit centers and also takes into account the randomness in passengers' arrival flow and service time. Sensitivity analysis is conducted under different settings of passengers' arrival flow, coefficient of variation (CV) and dimensional features (length and width of transfer zone). The results showed that the passengers' arrival flow, CV and width of the transfer zones are highly influential parameters, while the length of transfer zones has no significant influence. Therefore, during the design phase of transit centers, emphasis should be given to influential parameters as they illustrate the actual conditions in the transit centers.
