Evacuation Experiments for Wheelchair User and Pedestrian Group

Abstract

Disabled people including wheelchair users have been going out into a society rnore actively ， Then TRAIL ( Transportation and Accessibility Law )carne into effect in May 2000 ． Barrier − free passenger ships are going on increas 至 ng by those activities ． Barrier − free passenger ships must maintain highly evacuation safety on board ． One of items for evacuation safety on board｛ s that wheelchair users and pedestrian passengers can move together to assembl ｝ 厂 spaces smoothly ． We did experiments that a wheelchair user and 30 walkers escaped together through passenger sh ｛ p corridor mQck − up which length was 15m ． The width of the cQrridor was 2 m and 3 m ． We did 4 cases for doorways which width were 21n and 3 m within the corridor which width was 5 m ． A video camera that was set 30m above the corridor recorded the behavior of the wheelchair user and the walkers ． The wheelchair user and the 30 waikers were able to move through the corridor withQut a decline in the evacuation speed with all conditions of the experime ' nts ． But conditiolls of both the wheelchair user and walkers influenced each other to their behavior ． A kind mental state of the walkers had the wheelchair user feel at ease ， The cases with the doorways which width of 2 m showed a decline in the flow ( persons ／ sec ． )arld its value was one to two persons／ sec ． Key words ：human engineerin 皇， wheelchair user ， evacuation safety Qn board ， barrier − free passenger ship

Fundamental diagram of pedestrian flow including wheelchair users in straight corridors

“…There are also studies that have paid attention to the movement of pedestrians mixed with wheelchair users recently. Feliciani et al [23] found that information on exits provided to wheelchair users can increase the evacuation efficiency in a room with Type: electrically and Wheelchair users: [24] manually self-propelled fixed speed; and assisted wheelchair normal people: users; number: 1 kindness, competitiveness Tsuchiya et al Japan 1.2, 1.4, Type: assisted Normal walking [25] 1.6, 1.7, wheelchair users; 1.8, 2.0 number: 0-3 Shimada and Japan 3 Type: self-propelled Normal walking Naoi [26] and assisted wheelchair users; number: 0-4 Geoerg et al Germany 0.9, 1.0, Type: assisted Normal walking [18] 1.1, 1.2 wheelchair users (with disability); number: 7 The author (more China 2.1 Type: assisted Normal walking details in section 2) wheelchair users; number: 6 four exits. With respect to the corridor scenarios, the experimental setup and conditions of the corresponding studies are summarized in table 1.…”

“…With respect to the corridor scenarios, the experimental setup and conditions of the corresponding studies are summarized in table 1. A slower speed of pedestrians overtaking wheelchair users with the assisted type compared to the self-propelled type of wheelchair is observed from a corridor experiment conducted by Miyazaki et al [24]. Concentrating on assisted wheelchair users, some studies have investigated their movement characteristics.…”

A large-scale controlled experiment on pedestrian walking behavior involving individuals with disabilities

“…Wright et al (1999) evaluated walking speed of 30 individuals with visual impairments through an egress route. Miyazaki et al (2003) carried out a series of experiments using 30 participants and one participant with a wheelchair to describe the behavior of individuals encountering an individual using a wheelchair in a corridor with variable widths. Daamen and Hoogendoorn (2011) conducted an experiment to investigate the capacity of doorways with consideration of the elderly and people with disabilities in the Netherlands.…”
