The Run-Off-Road Collision Avoidance Using IVHS Countermeasures program is to address the single vehicle crash problem through application of technology to prevent and/or reduce the severity of these crashes. This report describes and documents the supplemental analysis sequence completed for Task 1. This supplemental analysis sequence was conducted to characterize the problem of run-off-road crashes in heavy trucks, as compared with the passenger vehicle analysis conducted in the original Task 1 effort. The sequence included three distinct analysis types which may be summarized as follows: Statistical Analyses-The GES and FARS national crash databases were examined to provide an updated estimate of problem size and to establish characteristics of the nation crash population. Clinical Analyses-A sample of case reports from the NTSB crash database were evaluated to determine crash causation factors and to establish the circumstances in which these crashes occur. Engineering Analyses-A subset of the NASS CSD case reports were examined to establish the dynamic scenarios associated with the clinical sample. These scenarios were represented as situation trees, which delineated the specific combination of driver, vehicle, and environmental factors in crash and driver response to critical events.
