Evaluation method for easy wayfinding of escape routes by configuration factora

We conducted a survey about signage setting conditions of escape routes in some public transport facilities using measurement method of configuration factor in the evacuee,s visual field constructed in our previous research. The survey was done at international airport terminals and subway stations in Japan and Thailand. Moreover we also did subjective evaluation experiments (easy-difficult to find escape routes) at the same points with the survey about signage setting conditions. And then the relational expression betweensign,s configuration factors and ease ofwayfinding was derived by the multiple regression analysis. Finally we evaluated the effects of signs installation for evacuation using the survey results and the evaluation equation..
