TL;DR: In this article, the authors present an analysis of the travel, crash frequencies, and crash rates of large trucks registered in Michigan, focusing on the travel and crashes of Michigan-registered trucks in Michigan.
Abstract: This report presents an analysis of the travel, crash frequencies, and crash rates of large trucks registered in Michigan. The project focused on the travel and crashes of Michigan-registered trucks in Michigan. The travel data are from the UMTRI Michigan Truck Trip Information Survey (MTTIS). Crash frequencies are from the computerized file of police accident reports maintained by the Michigan State Police, supplemented by data on the state-of-registration of involved trucks compiled by Michigan State University. The project was undertaken jointly by UMTRI and the Michigan State University Department of Civil and Environmental Engineering. The research approach and survey methods are described. Estimates of the travel and population of Michigan-registered tractors are presented, along with crash frequencies for several subsets of interest. The factors addressed in the risk analysis are: truck type, crash severity (fatal, injury, property-damage-only (PDO)), road type (limited access, major artery, other), urban/rural, day/night. The results indicate that the bobtail tractor configuration has the highest risk on all parts of the Michigan highway system. Crash rates for singles and doubles are quite similar overall, though the doubles rate is higher for casualty crashes on major artery and other roads. Limited access roads had the lowest rates, followed by major arteries, and other roads. Crash rates were lower in urban areas than rural. Overall, daytime rates were higher than nighttime. Casualty crash rates were higher at night, but PDO rates were higher during the day in both urban and rural areas, but particularly urban. Traffic density appears to explain the higher overall daytime rate.
