Abstract:

This paper attempts to develop a kind of quantificational method to evaluate the level of service for the facility. The basic idea which was derived from westerner is used for reference. According to the specific traffic situation in China, the situaiton which a bicycle is totally hindered by a group of sidebyside pedestrians is highlighted in this paper. The probalistic models for the calculation of hindrance frequency are developed for both the same and opposite direction. The evolution trends of hindrance frequency according to the pedestian flow and the width of sidewalk are illustrated by the given example. The research results can be applied to provide theory guide to the planning and designing of shareduse sidewalks.

Key words: engineering of communications and transportation, shared use path, level of service, probabilistic model, pedestrian flow
