Essay On Transport Capacity

Since transit capacity deals with the movement of both people and vehicles it is different than highway capacity, also it will be affected by the size of the vehicle and operating policy of the transit agency. But what generally control transit capacity are two factors first is the critical stops (BRT stop or LRT stop/station) where boarding or alighting off passengers takes place, the second factor is the station or point the vehicles terminate or turnaround from. The capacity of stops is actually determine the capacity of the public transit system, and the real bottlenecks for transit operations happen there.

As a consequence, the capacity of the system will be limited by the capacity of the critical stop at the critical period; that is the stop in which the boarding or alighting rate is highest (Fernandez and Planzer, 2002). The definition of capacity will be introduced first, and reviews

Peak passenger demand volumes must be accommodate by headway along routes of LRT and BRT systems in order to have a sufficient headway. The dwell time and the ratio of the green time to the cycle length (g/c ratio) for the street on which the transit operates have the greatest influences on loading area vehicle capacity.

The capacity of LRT and BRT systems vary in ROW, vehicle types and operation (Vuchic, 1981). The following reviews the previous studies related to LRT and BRT capacity, including the capacity analysis conducted in the 2000 edition of the Highway Capacity Manual (HCM) and 2003 edition of the Transit Capacity and Quality of Service Manual (TCQS). These current publications provide a detailed analysis of LRT and BRT operation in terms of person and vehicle capacity analysis.
