Analysis on Performance of Driver Distance Recognition To Crossing Pedestrian at Night

In order to determine a reasonable maximum speed limit value and luminance at crosswalk at nighttime, it is necessary to study performance of driver distance recognition to a pedestrian crossing at night. An experiment was carried out on six segments in Harbin, China. Based on trips made by eight drivers during the night on these segments, driver recognition distances (distance between a pedestrian and the location where the pedestrian was clearly recognized the first time) were recorded. The data analysis results show that driving speed increases, recognition distance decreases; luminance decreases, recognition distance decreases. With the collected data, multivariate a non-linear regression relation model was established among driver recognition distance at night, driving speed, and average luminance.
