Multinomial logit model (MNL) was selected to estimate the explanatory variables at a 95% confidence level. The six-year crash data (2005-2010) were obtained in the State of Florida, USA and five injury level outcomes, no injury, possible injury, non-incapacitating injury, capacitating injury, and fatal injury, were considered. The no injury level was selected as the baseline category. %K Contributing Factors %K Nighttime Crash %K Injury Severity %K Freeway Mainline %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=95412
