“…It should be noted that the spatial characterization that a pedestrian has when combining a large part of these variables has already been studied previously. More recent studies done by Seriani et al [31] reported in different scenarios the effect of the ratio between passengers boarding and alighting, using a mock-up of a London Underground train at a laboratory facility. Using also experiments, Geoerg et al [32] studied the movement of passengers in a bottleneck and a corridor.…”

The objective is to study the space a wheelchair passenger would use in the preferential waiting areas of an urban railway platform. For this purpose, an analysis of the variables that interfere in the space occupied by a wheelchair user was carried out at Metro de Santiago platforms, to design a preferential prototype waiting area at the Human Dynamics Laboratory of the Universidad de los Andes (Chile). The prototype has a 3.0 m long and 2.5 m wide carriage, together with a preferential waiting area on the platform of the same length as the carriage, and 2.0 m wide. With this prototype defined, a detection method was developed using PeTrack software, to accurately identify the limits of the space occupied by a wheelchair user under two scenarios of different density levels in the preferential waiting area: medium-density (1.5 passengers/m2) and high-density (4.0 passengers/m2). It was observed that the space occupied by a wheelchair user decreased by 33% as the density increased from medium to high. On the other hand, for a high-density level, the space occupied by a wheelchair user was found to be 61% higher than that occupied by a passenger without reduced mobility. This variation occurred mainly because passengers increased their distance from the wheelchair user, which widened their area of influence. Further experiments are proposed as future research to extend this analysis using other density situations.

“…Recently, some authors [34][35][36][37] reported that platform edge doors have no important impact on the dwell time, but the interaction is influenced by other variables such as the formation of lines of flow, distance between passengers, speed and space used by each passenger.…”

“…Therefore, several laboratory experiments are performed, including the Pedestrian Accessibility Movement Environment Laboratory (PAMELA). In a laboratory, certain variables can be changed while keeping the others constant, which allows the study of the influence of a single factor [35,37,65]. A series of experiments were conducted at the PAMELA using a full-size mock-up train carriage and a platform in order to obtain empirical evidence for the passenger boarding activities.…”

The Influence of the Density Inside a Train Carriage on Passenger Boarding RatePassenger alighting and boarding time is an important factor for crowded metros with high frequency operations. Some operators leave the train doors open until the last passenger boards or passengers voluntarily stop boarding, while others regulate the boarding process. To evaluate whether it is effective to regulate the passenger while boarding or not, this research explores how the density inside the train would influence the passenger boarding rate by conducting a laboratory experiment. The results showed that the passenger boarding rate increased as the density increased, up to approximately 2.5-3.0 passengers/m 2 . Beyond that point, our results suggested that the boarding rate may have decreased, but the evidence was not conclusive. It is deduced that, under the experimented density (up to around 5 passengers/m 2 ), the density does not have any apparent negative effects on the boarding rate, which implies that there is no strong evidence to recommend passenger boarding regulation.

“…As field studies are in most cases not suitable to analyse the effects of certain parameters independently, several experimental studies have been conducted in order to determine factors that have an influence on the boarding and alighting times. Exemplary variations performed were different ratios of boarding and alighting passengers [14] and train design factors (e.g., door widths and number of doors [11,[15][16][17][18][19], horizontal and vertical gap sizes [17,18,20,21], vestibule setback [17,18], boarding and alighting through different doors [22]). The types of passengers influence the boarding and alighting times, as age or the presence of luggage are factors that should be considered [23,24].…”

The functionality of railway platforms could be assessed by level of service concepts. They describe interactions between humans and the built environment and allow one to rate risks due to overcrowding. To improve existing concepts, a detailed analysis of how pedestrians use the space was performed, and new measurement and evaluation methods are introduced. Trajectories of passengers at platforms in Bern and Zurich Hardbrücke (Switzerland) were analysed. Boarding and alighting passengers show different behaviour, considering the travel paths, waiting times and mean speed. Density, speed and flow profiles were exploited and a new measure for the occupation of space is introduced. The analysis has shown that it is necessary to filter the data in order to reach a realistic assessment of the level of service. Three main factors should be considered: the time of day, the times when trains arrive and depart and the platform side. Therefore, density, speed and flow profiles were averaged over one minute and calculated depending on the train arrival. The methodology developed in this article is the basis for enhanced and more specific level of service concepts and offers the possibility to optimise planning of transportation infrastructures with regard to functionality and sustainability.
