• Abstract:
  The attached report is from the NHTSA sponsored program, "IVHS Countermeasures for Rear-End Collisions," contract #DTNH22-93-C-07326. This program's primary objective is the development of practical performance guidelines or specifications for rear-end collision avoidance systems. The program consists of three Phases: Phase one: "Laying the Foundation" (Tasks 1-4), Phase two: "Understanding the state-of-the-art" (Tasks 5 & 6), and Phase three: "Testing and Reporting" (Tasks 7-9). This work focuses on light vehicles only and emphasizes autonomous in-vehicle-based equipment (as opposed to cooperative infrastructure-based equipment.) The results and conclusion presented in this interim report are preliminary in nature. The Task 2 report "Functional Goals" presents the functional goals developed for three basic types of rear-end collision avoidance and related systems (Driver Warning System (DWS), Intelligent Cruise Control (ICC) System, Automatic Control System (ACS)). In addition, the report presents the dynamic situations relevant to the rear-end crash problem. These dynamic situations allow the events leading to accidents, and accidents themselves, to be subdivided into smaller groups that can be addressed individually. To establish the functional goals, a taxonomy of collision subsets and crash-related events that provide a basis for identifying opportunities for intervention in the sequence of events leading to a crash was developed. The functional goals established for each of the system types is based on this taxonomy. The report also established the terms and definitions as they relate to this program. This is done to provide background into the rear-end collision avoidance problem and to standardize on definitions and terminology. THE RESULTS PRESENTED IN THIS REPORT ARE BASED ON A LIMITED AMOUNT OF WORK CARRIED OUT WITH LIMITED INTERACTION WITH THE ACADEMIC, RESEARCH, AND INDUSTRY COMMUNITIES. ANY CONCLUSIONS DRAWN FROM THE RESULTS PRESENTED MUST BEAR THIS IN MIND. Phase two goals include a detailed state-of-the-art review of technologies related to rear-end collision avoidance systems and the design of a test bed system(s). Phase two will finish in mid-June 1996. Phase three goals include the building and use of the test bed system, the generation of the final performance guidelines or specifications, and the final reporting on all aspects of the project. Phase three will finish in early 1998. Work continues through Phase two and three to add to, and to refine, the preliminary performance guidelines or specifications presented in the Task 4 report.
