Abstract
The aim of this paper is to examine pedestrian behavior and suggest guidelines for analyzing pedestrian traffic flow in narrow urban streets with mixed traffic. For the analysis of pedestrian behavior, 15 streets around urban railway station in Tokyo were surveyed and several parameters obtained such as: pedestrian paths around stationary obstacles; share of pedestrians using the sidewalk as a factor of street environment and traffic conditions; and influence distance of and for with respect to bicycles and cars. In terms of planning guidelines, the authors have defined simultaneously a new index of timespace occupancy (Qt-si) of traffic modes in mixed traffic conditions which considers the occupancy of time and space in the time-space diagram. Also, a new concept for level of service (LOS) standards has been suggested for mixed traffic conditions, which employs concept of time-space occupancy of each modes and hindrance/conflict between modes
