The National Highway Traffic Safety Administration's Office of Crash Avoidance Research, in conjunction with the Research and Special Programs Administration's Volpe National Transportation Systems Center, has underway a multi-disciplinary program to identify crash causal factors and applicable Intelligent Vehicle-Highway System countermeasure concepts, model crash scenarios and avoidance maneuvers, provide preliminary estimates of countermeasure effectiveness when appropriate, and identify research and data needs. To date, five crash types have been examined which include rear-end, backing, single vehicle roadway departure, lane change, and intersection/crossing path crashes. This paper describes the methodology employed in analyzing crash scenarios and developing functional countermeasure concepts independent of specific technologies. The causal factors of the five crash types mentioned above are synthesized in separate categories dealing with the driving task, driver physiological state, and the driving environment. |
