Collision Analysis Of Vehicle Following Operations By Two-dimensional Simulation Model: Part I - Effects Of Operational Variables

This research project investigates the behaviors of vehicles in collisions, especially when they are closely spaced. The study uses a two- dimensional simulation program, EDSMAC, which allows longitudinal and lateral movements as well as the yaw motion of vehicles. The simulation model calculates impact forces in collisions and estimates the resulting vehicle damage. Collision situations are simulated. The subsequent post- impact vehicle trajectories are then analyzed. By varying parameters in simulation cases, one can evaluate the potential effects of such variables in vehicle-following operations.
