ABSTRACT
The installation of the pedestrian crosswalk is a problem involving many factors such as vehicle volume, pedestrian volume, etc. In order to comprehensively consider the influence of various factors on the setting of mid-block pedestrian crosswalk and ensure the safety of pedestrians, the synthetic factors method considering the traffic volume, road conditions, traffic environment, and other factors was adopted to construct the model for the installation of mid-block pedestrian crosswalk, and the parameters of model were calibrated; then, the decision flow of mid-block pedestrian crosswalk was installed and the threshold value W0 was determined through simulation analysis, when the value of the calculated mid-block crossing location W is greater than the threshold value W0, the setting of the pedestrian crosswalk is considered. In order to further test the model validation, this method and other methods are used to compare the installation of pedestrian crosswalk on 15 mid-block crossing locations in Nanjing. Finally, a mid-block crossing location in Nanjing is taken as the research object to analyze pedestrian crosswalk installation, and the conclusion that this crossing location is recommended to set crosswalk is obtained. Compared with the warrant of crosswalk installation in the past, the synthetic factors method considers a series of influence factors comprehensively, which can effectively ensure the safety of pedestrians and realize the reasonable mid-block pedestrian crosswalk installation.
