Nationally, approximately one third of all motor vehicle crash fatalities involve alcohol-impaired driving. According to the National Highway Traffic Safety Administration (NHTSA), alcohol-impaired motor vehicle crashes cost more than an estimated $37 billion annually. Alcohol impaired driver behavioral activities and demographic characteristics are needed for composing effective countermeasures and developing proper policies against traffic crashes and reducing related costs. This study focuses on the impacts of alcohol impaired driver behavior and characteristics on traffic crash severities at intersections in New Mexico. Statistical analyses were conducted to identify the most significant alcohol impaired driver behavioral activities and demographic characteristics and time periods of driving. The transportation econometric models, multinomial Logit regression models, were developed to analyze crash severities for regular drivers and alcohol impaired drivers using the data collected from the State of New Mexico from 2010 to 2011. The research findings provide a better understanding of traffic alcohol-related accident causes in New Mexico that will help transportation agencies and decision makers find cost-effective solutions for reducing the severity of crashes to improve safety and enhance policy development.
