This document constitutes a final report for MOU309. The report contains a User's Manual, Programmer's Guide, source code and underlying theory for the program Medusa . This program is capable of simulating both the normative driving dynamics and collision dynamics of an arbitrary number of vehicles. Its range of validity lies in the assumed nature of the vehicular collision, and it is recommended for use in studying low relative velocity impact scenarios at large time-scales. A significant portion of this report is devoted to presenting the vehicle and road models. The former model is composed of tire, collision, suspension, and sprung mass models. It is also augmented by a collision detection algorithm. The road model is sufficiently general to encompass variations in banking and sloping of the highways. The report also contains the simulation results of several representative vehicular collision scenarios. These results are supplemented by the input files for Medusa and the visualisation program SmartPATH . Several features of these examples are also discussed in the light of the improvements to Medusa that they motivated. (A)
