Differences Between EDCRASH and CRASH3 850253

Motor vehicle accident researchers have used the CRASH computer program for some time. Over the years, the code was upgraded until it reached its present and popular form, CRASH3, which runs on a mainframe computer or minicomputer with a sizeable memory capacity. A new version of the program, EDCRASH, has been developed which runs on personal computers using 128K of memory. This paper describes and compares this program with its mainframe counterpart. The program performed the same function as CRASH3, but was designed as a screen-oriented program utilizing the environment of the personal computer. Its design also allowed for file saving, graphics, routing of output, and interfacing with other accident reconstruction programs. For most accident types, the results for both programs were identical. However, for some types the results were different.
