Abstract:This report describes pre-crash scenarios involving at least one heavy truck (gross vehicle weight rating greater than 10,000 pounds), which might be addressed with crash-imminent warning systems based on short range vehicle-to-vehicle (V2V) communications. The analysis focuses on 17 target pre-crash scenarios that are statistically described using the 2004-2008 General Estimates System (GES) crash databases and the Large-Truck Crash Causation Study (LTCCS) database. GES data is queried to quantify the societal cost and describe the driving environment, driver characteristics, and crash contributing factors of target pre-crash scenarios. LTCCS data is analyzed to portray crash causal factors. Approximately 233,000 annual police-reported crashes involving at least one heavy truck were associated with the 17 target pre-crash scenarios. These police-reported crashes contributed to about 21 billion dollars in comprehensive economic costs based on 2007 economics and 153,000 functional years lost annually. Heavy-truck drivers of interest accounted for about 57 percent of all drivers involved in these crashes.
