The Effect of Rain on Pedestrians Crossing Speed

The pedestrian crossing speed in the signalized intersections is one of the most important parameters in the designing intersections and also is essential information in controlling the amount of delay and traffic. The present study aims to measure and statistically analyze the pedestrian crossing speed according to the weather conditions, which is either normal or rainy. In order to do this, the crossing speed of ۴۳۸۱ pedestrians has been gathered through the photography of two signalized intersections in Rasht city. Furthermore, these findings have been analyzed through the Independent Sample T-Test. The results show that, with a ۹۵ per cent confidence, in both gender groups of men and women, the difference in the pedestrian speed according to the weather conditions of either normal or rainy is statistically meaningful and the pedestrian crossing speed was significantly more in the times of rain than in normal weather conditions. Meanwhile, in Rain Condition s, the ۱۵th percentile crossing speeds for men and women increase ۳.۰ per cent and ۲۱.۵ per cent according to ۱۵th percentile speeds in the normal weather conditions respectively. Therefore, it is suggested that the pedestrian speed in the normal weather conditions be regarded as the base for designing, so that the ۱۵th percentile crossing speeds and the average of all samples in the Rain Condition are ۱.۰۵ and ۱.۲۴ meter per second successively.
