Modeling Bus Lost Time: An Additional Parameter Influencing Bus Dwell Time and Station Platform Capacity at a BRT Station Platform

The common approach to estimate bus dwell time at a bus rapid Transit (BRT) station is to apply the traditional dwell time methodology derived for suburban bus stops. In spite being sensitive to boarding and alighting passenger numbers and to some extent towards fare collection media, these traditional dwell time models do not account for the platform crowding. Moreover, they fall short in accounting the effects of passenger/s walking on a relatively longer BRT platform. Using the experience from Brisbane busway stations, a new variable, Bus Lost Time (LT), is introduced in traditional dwell time model. The bus lost time variable captures the impact of passenger walking and platform crowding on the bus dwell time. These two characteristics which differentiate a BRT station from a bus stop. This paper develops a methodology to estimate bus lost time experienced by buses at a BRT platform. Results were compared with the Transit Capacity and Quality of Service Manual (TCQSM) approach of dwell time and station capacity estimation. When the bus lost time was used in dwell time calculations it was found that the BRT station platform capacity reduced by 10.1%.
