Exploring Contributing Factors to Driver Injury Levels during Nighttime at Local Collectors

This study investigated the nighttime crash characteristics at local collectors. The multinomial logit model (MNL) was selected to estimate the contributing factors to different injury outcomes for nighttime crashes. The latest six-year crash data (2005-2010) were obtained from the Florida Crash Annual Report (CAR) System. Five injury level outcomes -- no injury, possible injury, non-incapacitating injury, capacitating injury, and fatal injury -- were considered. A total of 824 crashes was observed in local collectors. Five explanatory variables -- posted speed limit, lighting, single vehicle, truck/bus, and age -- are significant at a 95% confidence level. Street light presence is the most significant factor to the injury outcome at local collectors. A single vehicle crash could significantly increase the possibility of all injury outcomes compared to a multi-vehicle crash. The odds ratios suggest that having street lights could reduce the relative risk of suffering incapacitating injury or fatal injury at local collectors.
