A FORTRAN PROGRAM FOR GRADE CROSSING COLLISIONS STUDIES USING COMPUTER GRAPHICS
A computer program is presented in the FORTRAN language to simulate the co-planar dynamic response of vehicles to the collision situation in which a rail vehicle impacts a highway vehicle at a grade crossing. The simulation incorporates 28 individual parameters associated with vehicle geometry, initial conditions, and other variables describing vehicle structural characteristics and a point-mass occupant situated inside the struck vehicle. A complete listing of the program is given along with descriptions of the program logic, sample input and output. Inputs include the mass, velocity, and force-deflection properties of each vehicle. The displacements and rotations of the vehicles are calculated as well as the penetration of the highway vehicle and the accelerations of its occupant compartment. As a special feature, this program is capable of producing computer generated diagramatic aerial-view movies of the collision event representing a locomotive striking a sedan broadside. (Author)
