Abstract
The transitional pedestrian flow evaluate method is like the traffic flow by the density,flow and speed, but the method could not evaluate the pedestrian conflict. Because pedestrians have moved more freedom then car. So this study wants to establish a new method to provide the planner and manager to evaluate the pedestrian facility. According to the observation, this study builds on two conflict indexes, the first one is conflict entropy which to calculate the pedestrian variance of walking speed, another one is dodge ratio which to evaluate the degree of pedestrian departure when pedestrian run into conflict. The result shows the conflict and density, direction ratio has positive liner relation, the speed has the negative relation, and the conflict entropy and dodge ratio have the positive liner relation. Besides, in order to provide more effective indexes to the planners and managers, this study has also divided six conflict index scales by fuzzy theory.
