Summary

This report, issued by the National Highway Traffic Safety Administration (NHTSA) in January 1997, updates Congress on the progress of the Intelligent Transportation Systems (ITS) program from 1992 to 1996 and outlines the strategic plan for 1997–2002. The document addresses the research question of how advanced technologies can be developed and deployed to reduce traffic accidents, injuries, and fatalities. Motivated by the recognition that widespread deployment of effective collision avoidance technologies was a decade away, NHTSA initiated a strategic plan to establish the necessary knowledge base, research tools, and prototype development activities to facilitate early deployment. The methodology involved extensive statistical and causal analysis of accident data to identify primary crash types and contributing factors. NHTSA developed new research tools, including the National Advanced Driving Simulator (NADS), the Data Acquisition System for Crash Avoidance Research (DASCAR), the System for Assessing the Vehicle Motion Environment (SAVME), and the Variable-Dynamics Test Vehicle (VDTV). These tools were used to study driver behavior, quantify vehicle motions, and test prototype systems. The program focused on identifying promising crash avoidance opportunities, demonstrating proof-of-concept systems, and facilitating commercialization through partnerships with the automotive industry. Specific efforts included developing performance specifications for countermeasures in eight safety-related areas: rear-end, road-departure, intersection, lane change/merge, drowsy driver, reduced visibility, heavy vehicle stability, and automated collision notification. Key findings from the 1992–1996 period indicate that rear-end, intersection, and road-departure collisions account for nearly 75% of all crashes, guiding the focus of mitigation efforts. NHTSA successfully compiled a comprehensive collision avoidance knowledge base and established preliminary performance specifications for various systems. Operational tests were initiated for Intelligent Cruise Control and Automated Collision Notification systems. The report highlights that causal analysis revealed the critical need to address driver-vehicle interactions, as driver performance factors such as drowsiness and reduced visibility contribute significantly to accidents across all crash types. The significance of this report lies in its establishment of a framework for the next generation of vehicle safety systems. The 1997–2002 strategic plan continues to emphasize the use of advanced ITS technologies to prevent crashes, moving beyond conventional safety enhancements. NHTSA aims to refine performance standards, assess user acceptance and market potential, and estimate the benefits of these systems in terms of reduced collisions, injuries, and economic costs. The report underscores the importance of cooperation between government agencies and industry to expedite the commercialization of crash avoidance technologies, ensuring that new systems enhance safety without compromising usability or increasing driver workload.

Key finding

The report serves as an administrative progress update and strategic plan rather than a study with empirical results, detailing the development of research infrastructure and the identification of rear-end, intersection, and road-departure collisions as primary targets for safety improvement.
