Abstract: Pedestrian traffic is an important component of urban transportation system, accounting for a large proportion of total urban trips. However, during the rapid motorization and urbanization over the past 20 years in China, more attention has been paid on motorized vehicles, while pedestrians' requirements are quite often neglected. This paper analyzes the pedestrian- vehicle conflicts at urban intersections, and points out the deficiencies of pedestrian crossing facilities in planning, design, signal control, as well as related traffic laws and regulations. In terms of pedestrian clearance signal, this paper proposes to use flashing red in China. Finally, the paper proposes several signal control strategies that may be effective under certain conditions to reduce the conflicts between pedestrians and right- and left- turn vehicles.

Keywords: urban street intersection; pedestrian crossing; signal control; pedestrian clearance interval; reduce pedestrian-vehicle conflicts
