A two-phased study was conducted to determine the feasibility of training drivers to acquire skills needed to avoid critical conflict motor vehicle accidents, and to develop the procedures and materials necessary for such training. Basic data were derived from indepth accident investigations and task analyses of driver behavior. Principal products/activities of the study (developed in phase II) were (1) a comprehensive curriculum and performance measurement specification (which includes seven modules) adaptable to local needs and resources; (2) definition, development, and preliminary testing of a bimodal simulator which can be used for training drivers in key collision avoidance skills; (3) definition of an Advance Driving Range concept, and (4) identification of research problems. This report is divided into four sections. Introductory and background material is included in section 1. Section 2 is a discussion of the components of phase 1--accident and task and behavioral analyses, and collision avoidance experiments. A discussion of phase 2 components (section 3) covers training/testing requirements definition, simulator definition and development, and the driving range concept. Also included are conclusions/recommendations and future research and development requirements. Appendixes include a bibliography of accident avoidance skill training literature; (2) curriculum and performance measurement specifications for accident avoidance skill training (seven modules), and (3) bimodal simulator descriptive materials.
