摘要：Pedestrian is one part of transportation system that its existence and importance should not be ignored in the transportation system planning process. Crossing facility at intersection which not equipped with traffic signal are high risk area for pedestrians. This paper discuss about gap that can be received by pedestrians when they will cross the road by analyzing the movement of vehicles in the traffic flow. Data are taken by video recording and direct observation on the intersection. The authors study and use several methods that have been used in previous literatures: Raff’s method, Harder’s method, and Wu’s method. The authors analyze and compare the results of those method to find which one is the most appropriate to the actual condition. The results show the value of critical gap from each methods and the factors which affect it.
