METHODS FOR JUDGING THE BEGINNING POINT OF AVOIDING BEHAVIOR AND AVOIDANCE DISTANCE BETWEEN A PEDESTRIAN AND A STANDING OBSTACLE : A study on pedestrian behavior of avoiding obstacles (II)

Abstract

The characteristics of pedestrian behavior avoiding obstacles is discussed in this paper. The results are summarized as follows : (1) The most appropriate method to define automatically the beginning point of avoiding behavior was found to sellect the point where the curvature is biggest. (2) According to this method, some distances between a point of a pedestrian starting to avoid and a point of a standing obstacle : Sx were measured. The Sx of each obstacle is different, and it's value is 6.74m for a person backwards, 6.82m for one sideways, 8.84m for one facing to and 7.34m for an object.
