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. (Included with the report is a diskette of the kinematic models developed for this crash type and files for data tables used in generating data plots contained in the report. The file README.TXT is an ASCII file that describes the program and data files on this diskette. (Author/publisher)
