Crash Severity Formulation and Analysis under Extreme Weather Conditions

This study focuses on vehicle crash with respect to extreme weather condition in the state of New Mexico. In the southwest region, unique weather extremes, including enormously high temperature, strong wind, flash flood, fog, dust, snow, etc., have resulted in more frequent and serious traffic crashes. For example, 501 traffic crashes were reported under extremely windy conditions in New Mexico in 2011. Although they only accounted for 1.2% of total crashes but result in about 3.4% of total fatalities. Under foggy conditions, fatal crashes account for 2.5% of total crashes, which is much higher than 0.7%, the proportion of fatal crashes to total crashes under regular weather conditions in New Mexico in 2011. These statistics dramatically illustrate that traffic crashes impacted by weather extremes are more serious than those under regular weather conditions. The current study attempts to develop a database of vehicle crash with respect to extreme weather condition. Statistical models are developed and analyzed to find a correlation of vehicle crash with extreme weather conditions.
