EDSMAC / CARMMA

EDSMAC is a simulation program developed by Engineering Dynamics Corporation(EDC). The software package, EDSMAC(Engineering Dynamics Corporation Simulation Model of Automobile Collisions), is used for the analysis of a single or two-vehicle accident. It is based on a program called SMAC which was initially developed by Calspan Corp. and subsequently improved by EDS. EDSMAC uses a set of assumed or estimated initial conditions, including positions and velocities, and preducts the outcome of a collision. The output data is animated using Carmma. Carmma is a tool that allows a user to specify highway scenarios, animate them and create data files. Carmma is used only to animate SMAC simulation data in this application. It is described in the Carmma User's Manual. The source code and programs for SMAC and Carmma can be downloaded for use on UNIX platforms.
