Abstract
The purpose of this paper is to clarify the level of walking difficulty through crowd flow. Four subjects crossed a crowd flow in a terminal station at four separate penetration angles each; 45 degrees, 90 degrees, 135 degrees. The crossing pedestrian's difficulty was analyzed from both the human movement and psychological aspects. The result of the analysis is as follows : 1) Mental evaluation of crossing difficulty has a close relation to the crowd density. The perception of crossing difficulty showed the greatest change between 0.25 person/m^2 and 1.0 person/m^2. 2) Mental evaluation of a 45 degree crossing angle was more favorable than one of 135 degrees. 3) The results of physical analysis were the same as mental evaluation. 4) The crossing subject tended to cross behind crowd pedestrians. In the case of high density, the avoidance behavior becomes complex, using changes of speed and locus.
