COLLISION ANALYSIS OF VEHICLE FOLLOWING OPERATIONS IN AUTOMATED HIGHWAY SYSTEMS

In Automated Highway Systems (AHS), vehicles are automated to maintain a desired speed and safe distance from the preceding vehicles. The vehicles also maintain their positions within a lane or on their designated path. One of the safety concerns for such systems is the consequences in failure or malfunctioning events when collisions occur. The work presented by this paper investigates the responses of vehicles in collisions, especially when they are closely spaced. This study used a two-dimensional simulation software 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, representing failure or malfunctioning events, are simulated. The subsequent impact vehicle trajectories are then analyzed. Through a systematic approach, correlation between the collision consequences and the operating variables in AHS can be established. The results of this analysis may also provide valuable inputs to the design of control systems. Proper emergency handling strategies and control laws may be developed to mitigate collision consequences.
