Identification of Vehicular Impact Conditions Associated with Serious Ran-Off-Road Crashes

The primary goal of roadside design is to limit the number of serious injuries and fatalities associated with ran-off-road crashes. Roadside geometrics and safety features have a strong influence on the frequency and severity of crashes. In order to design optimum roadside geometrics and to determine which roadside safety features are appropriate, it is imperative to identify impact characteristics associated with serious injury and fatal crashes. This information has a direct bearing on safety-evaluation criteria used to assess the performance of roadside safety features. However, the impact speeds, angles, and orientations used in the current testing procedures are selected to represent a practical worst case situation. It is unclear to what degree this practical worst case situation represents real world conditions. Consequently, it is important to have definitive data on whether there are real relationships between the selected test impact conditions and actual crashes involving serious injuries and fatalities. </font><font face="Times New Roman">Crash data will be useful in refining guidelines for roadside safety countermeasures and calibrating roadside safety models [e.g., Roadside Safety Analysis Program (RSAP)] and crash and vehicle dynamics simulation models. It will also be helpful in focusing designers' attention on the roadside features that are involved in the greatest number of serious injury and fatal crashes. Crash data will help designers spend safety dollars on improvements that will have the greatest likelihood of reducing serious injuries and fatalities. </font><font face="Times New Roman">The objectives of this project are (1) to identify the vehicle types, impact conditions, and site characteristics associated with serious injury and fatal crashes involving roadside features and safety devices and (2) to create a robust relational database for future research. </font><strong><font face="Times New Roman"></font></strong><br /><br />
