Traffic safety assessment between pedestrian-automobile near intersection

This study attempts to evaluate the risk of pedestrian, and to explore the factors that contribute to mortality and severe injury. According to the analysis and research on more than 10 thousand traffic accidents in Harbin, it was approved that signal control can reduce the intersection accident rate efficiently, compared to non-signalized crossing, the average reduced range can achieve to 40%. Considering that the vehicle flow was compressed to orderly impulse flow by signal, the paper discusses the pedestrian crossing gap base on the analysis of the pedestrian crossing features. A pedestrian risk factor PRF is introduced to evaluate the crossing risk of pedestrian by probability statistics mode and Hongqi Str. In Harbin is used to practice the proposed model. Finally, the most significant contribution this study is the newly proposed concept of pedestrian risk factor, a practical method to identify locations that are risky to the network and to determine improvement measures to specific freeways and large traffic generators/attractors via an analysis of pedestrian crossing and traffic flow record.
