This report provides an analysis of lane change crashes to guide the development of Intelligent Vehicle Highway System (IVHS) crash avoidance systems. It introduces the problem of lane change crashes: A lane change crash occurs when a driver attempts to change lanes and strikes or is struck by a vehicle in the adjacent lane. Two crash subtypes are identified and causal factors that contribute to lane change crashes are assessed clinically from a sample of lane change crash cases. From these data, functional goals for IVHS lane change crash avoidance systems are described. A simple kinematic model of normal lane change and evasive steering maneuvers introduces key pre-crash variables and outlines the space of time and distance available for crash avoidance from a kinematic perspective, concluding with a discussion of key research needed to extend the analysis presented.
