    About this Project
    Brief Project Description & Background
    In 2009, heavy trucks represented approximately 15% of the vehicle miles traveled (VMT) in Iowa (1), compared to 10% at the national level (2). Between 2006 and 2010 in Iowa, heavy trucks were involved in crashes resulting in, on average, 74 fatalities annually (3). Fifteen percent of these fatalities were large truck occupants (3). In other words, the vast majority of the resulting fatalities were non-large truck occupants, demonstrating the serious nature of these crashes when involving the general traveling public. While several national studies have investigated heavy truck crashes, e.g. "Large Truck Crash Causation Study", no rigorous analyses have been conducted in Iowa.
    Research Objective
    The objective of this project is to investigate the causes, locations and other factors related to heavy truck crashes in Iowa. Through efforts related to this study, the research team will provide results that may be used by decision makers and law enforcement, particularly Iowa DOT Motor Vehicle Enforcement (MVE), in establishing priorities and allocating limited resources to promote safety and reduce crashes.
    Potential Benefits
    The results of this effort should lead to a better understanding of heavy truck crash experience in Iowa, including a wide range of factors as well as location component, and relationships among licensure and citations. Results will be presented in the final report. A collaborative work plan will provide a framework for utilization of the analyses results to promote safety and reduce crashes.
    Abstract
    In 2009, heavy trucks represented approximately 15% of the vehicle miles traveled (VMT) in Iowa (1), compared to 10% at the national level (2). Between 2006 and 2010 in Iowa, heavy trucks were involved in crashes resulting in, on average, 74 fatalities annually (3). Fifteen percent of these fatalities were large truck occupants (3). In other words, the vast majority of the resulting fatalities were non-large truck occupants, demonstrating the serious nature of these crashes when involving the general traveling public. While several national studies have investigated heavy truck crashes, e.g. "Large Truck Crash Causation Study", no rigorous analyses have been conducted in Iowa.

    The objective of this project is to investigate the causes, locations and other factors related to heavy truck crashes in Iowa. Through efforts related to this study, the research team will provide results that may be used by decision makers and law enforcement, particularly Iowa DOT Motor Vehicle Enforcement (MVE), in establishing priorities and allocating limited resources to promote safety and reduce crashes.
