Abstract
In order to identify the road environment and other external causes influencing the occurrence of hit-and-run crash with casualty for enhence the road safety, and clarify the impact of these factors on injury severity in the crash, the paper employs the logistic regression model to examine external factors and crossing variables by the formation of dummy variables, based on the 2012~2014 road traffic crash data of Michigan, USA. The results indicate that nighttime, nighttime & within the lane, nighttime & weekend and rural road & nighttime have significant impacts on the occurrence of hit-and-run crash with casualty, while rural road, speed limit and rural road & within the lane are associated with the less likelihood of crash happening significantly. The well condition of the road surface, crashes occurred away from the intersection and road lanes can increase the probability of the injury severity in hit-and-run crash, while the better lighting condition, working day, daytime and urban road reduce the possibility of severe injuries happening. According to the analytic, it is necessary to strengthen the supervision of traffic at night, and more monitoring measures are needed at weekend night, rural road in evening, off-road space also.
