Train design features affecting boarding and alighting of passengers
© 2017 John Wiley & Sons, Ltd.Accurately predicting train dwell time is critical to running an effective and efficient service. With high-density passenger services, large numbers of passengers must be able to board and alight the train quickly - and within scheduled dwell times. Using a specially constructed train mock-up in a pedestrian movement laboratory, the experiments outlined in this paper examine the impact of train carriage design factors such as door width, seat type, platform edge doors and horizontal gap on the time taken by passengers to board and alight. The findings illustrate that the effectiveness of design features depends on whether there are a majority of passengers boarding or alighting. An optimum door width should be between 1.7 and 1.8 m. The use of a central pole and platform edge doors produced no major effects, but a 200 mm horizontal gap could increase the movement of passengers. There is no clear effect of the type of seats and neither the standbacks between 50, 300 and 500 mm. Further research will look for the relationship between the dwell time and the characteristics of passengers such as personal space.
