“…Walking speed studies are usually conducted in traffic engineering studies such as simulation of pedestrian movement in a corridor, sidewalk, or crosswalk [21], [22], [23], [24]. Sharifi et al [21] investigated the walking behavior of individuals with disabilities through controlled video tracking. Iryo-Asano and Alhajyaseen [22] investigated the behavior of pedestrian at signalized crosswalks under uncongested conditions.…”

This paper aims to identify factors influencing the walking speed of evacuees by conducting an evacuation drill in Padang, West Sumatera, Indonesia. A number of 18 volunteers and 6 observers, were gathered in an evacuation experiment on 3 routes with 5 segments each. The chosen routes are almost equal in terms of distance, but different in terms of the number of turning points. The experiment comprises of three cases in terms of the complexity of the route. These cases represent a simple, a medium and a complex route based on the number of turning points. The volunteers were asked to move, as if in an evacuation, to a particular place which was assumed to be a shelter. The observers were placed at some particular waypoints to record the time when an evacuee passes their location. The distance between the observers was measured using a manual distance meter. This study found that the average walking speed during the evacuation was 1.69 m/s. In addition, walking speed varied by age, gender, and walking distance. This finding significantly has an effect on the estimations of the coverage area of tsunami shelters. The data collection method is one of the novelties of this research. In this study, the walking speed was observed through an evacuation drill from a location to a shelter of 1.5 km away, whilst most of the previous studies estimate the walking speed based on an observation of a group of pedestrians crossing a road.

Experimental study of pedestrian flow mixed with wheelchair users through funnel-shaped bottlenecks

With the increase of the elderly and disabled in the world, the characteristics of pedestrian flow mixed with wheelchair users has being paid more and more attention.In this study, experiments in funnel-shaped bottlenecks were performed to study the impact of bottleneck shape and the ratio of wheelchair users on the crowd dynamics. It is found that the increase of wheelchairs in the crowd obviously leads to worse moving efficiency and congestion from the escape time, time-space relationship and time headway. Under low mixing ratios (<2.35%), less congestion occurred in the 45° bottleneck among the four tested angles (0°, 15°, 30°, 45°). The average speeds of wheelchair users is the fastest in 45° bottleneck (0.310±0.097m/s) until the mixing ratio arrives at 7.05%. However, the advantage of the angle disappears when the mixing ratio gets higher. The findings in this study is meaningful for the guidance of pedestrian evacuation through bottlenecks with the presence of wheelchair users.

“…About 2000 participants were involved in this series of experiments, including multilanes straight line movements in a corridor with a width of 5 m. Fundamental diagrams for different density measurements were presented and the estimated specific flow for unidirectional flow was 1.4 Ped/m/s at density level of 1.5 Ped/m 2 . Likewise, Sharifi et al (2017) conducted a series of laboratory experiments in a circuit corridor that contained straight line passageway [68,69]. Heterogeneity of crowd dynamics was investigated through the involvement of 189 normal people and 42 disabled people [70].…”

“…The collected data were further utilized to develop an optimal trajectories algorithm and to calibrate a cellular automation model [79,89]. Similarly, Sharifi et al (2014) and Sharifi et al (2017)'s experiments also included two angled corridors (right and oblique angle) as well as a spiral stairs with right corners [68,90]. Walking speed distributions and time-space diagrams for both homogenous and heterogeneous flows were analyzed from the calculation of extracted trajectories.…”

Complex movement patterns of pedestrian traffic, ranging from unidirectional to multidirectional flows, are frequently observed in major public infrastructure such as transport hubs. These multidirectional movements can result in increased number of conflicts, thereby influencing the mobility and safety of pedestrian facilities. Therefore, empirical data collection on pedestrians’ complex movement has been on the rise in the past two decades. Although there are several reviews of mathematical simulation models for pedestrian traffic in the existing literature, a detailed review examining the challenges and opportunities on empirical studies on the pedestrians complex movements is limited in the literature. The overall aim of this study is to present a systematic review on the empirical data collection for uni- and multidirectional crowd complex movements. We first categorized the complex movements of pedestrian crowd into two general categories, namely, external governed movements and internal driven movements based on the interactions with the infrastructure and among pedestrians, respectively. Further, considering the hierarchy of movement complexity, we decomposed the externally governed movements of pedestrian traffic into several unique movement patterns including straight line, turning, egress and ingress, opposing, weaving, merging, diverging, and random flows. Analysis of the literature showed that empirical data were highly rich in straight line and egress flow while medium rich in turning, merging, weaving, and opposing flows, but poor in ingress, diverging, and random flows. We put emphasis on the need for the future global collaborative efforts on data sharing for the complex crowd movements.
