Addressing Work Zone Traffic Safety Issues in Arizona

The statewide crash database maintained by Arizona Department of Transportation Traffic Records Section contains information provided as a result of a police investigation and physical evidence collected at the scene and witness statements. During the police investigation the crash contributing factors are identified and later are used by transportation professionals to provide and propose adequate safety countermeasures to minimize the number of crashes. Many police investigators are trained and certified to evaluate collision causation (e.g. Accreditation Commission for Traffic Accident Reconstruction or ACTAR certification). However, "accident reconstruction" is not a straightforward task, and frequently requires knowledge from other areas such as human factors and traffic engineering. Some of the methods applied during the police investigation may be incorrect and consequently may provide misleading opinions and misleading crash contributing factors. Additionally, a lack of knowledge in the area of human factors and traffic engineering make it more difficult for police investigators to truly identify crash causation, in particular, work zone related crashes. This study will analyze the causation of work zone related crashes. An analysis of work zone crashes should be performed by an expert in the area of traffic and transportation engineering with an understanding of human factors and "accident reconstruction" principles.
