The Design Method of Pedestrian Crossing Facilities on the Urban Expressway

With the development of the transit-oriented mode, lots of bus routes run on urban expressway and bus stop located at isolation belt between urban expressway and assistant-road. Based on the consideration of the car-pedestrian conflicts on assistant-road, this paper proposed a new design method of pedestrian crossing facilities on urban expressway. First, the crossing types have been described through analyzed the car-pedestrian conflicts on the assistant road. Second, based on the results of the car-pedestrian flows on the assistant road, which have been computed by the new method, the critical setting conditions figures of crossing facilities have been drew. Then the location of the overpass´s foot has been decided through the volume of crossing-street and riding-bus pedestrian. Final, a practical example in Beijing has been proposed to prove the feasibility of the method.
