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
Abstract. This paper focuses on the passenger traffic bottlenecks occurred in the bus route network in disaster situations and proposes the multi-agent based bus route optimization method to resolve such bottlenecks by generating the networks which can effectively transport many stranded persons including ones who wait around the station as the passenger traffic bottlenecks. For this purpose, the proposed method modifies the bus route networks generated as usual conditions to suitably pass many bus lines to and redistribute the buses among the bus lines according to the number of passengers. The intensive simulations have revealed the following implications: (1) the proposed bus route network optimization method generates the route network which is suitable for passenger traffic bottlenecks; (2) the proposed method decreases a risk of the bottlenecks; and (3) our method transports the passengers faster than those by the conventional one in various virtual disaster situations.
Transportation and Accessibility Law came into operation in Japan May 200 , which regulated barrier − free techrlical standard for ships as well as other transportation facilities . It is expected that Inore and more wheelchair users will make use of sea voyage because of the increase of barrier − free ships . But the influence of mixture of foot pedestrians and wheelchair users on evacuation safety has not yet been studied well and its investigation is a pressing need . This paper describes walk model of foot pedestrian group who is net into a panic and overtakes a wheelcha { r on passage . The model is designed based on the experiment that simulates evacuation of foot pedestrian group and a wheelchair user on straight passageway of ship . A Simulation program is developed faithfully based on the walkirlg human model and the validity of the model is investigated by comparlson of experimental results and simulated one . This model is expectedto be a base case for more complicated and more inf ! uential environment on evacuation safety on ships , 1ike stairs , doors and differences . Many conventional walking human models in escape analysis are designed by using physical phenome − non , such as poten 亡 ial energy and electromagnetic field , and so on . This mode ! uses sirnple cognitive cycle which includes predictiorl and modification , and uses simple behavior rules according to a distance to a wheelchatr . Despite of its simplicity and ease of descriptiQn 正 t realizes group action and it shows satisfactory performance . Key words : human engi . neering , wheelchair user , ship evacuation safety , walk model , simulation
