*The results are based on a benchmark run 11/27/95 on m-crash version 95.1.2. The inputs to the program consisted of only the impact and rest positions, vehicle damage measurements, vehicle weights, vehicle specifications and approximations for individual wheel drag and steer. No additional inputs were required (e.g., no inputs for point on curve, end of rotation, etc.). Complete input datasets will soon be published. The complete inputs will also be included with the m-crash program. Please see Reference 55 for a complete discussion of the refinements to CRASH.
