Almost all traffic accidents occur when a vehicle's stopping distance is greater than the distance headway between it and other vehicles or obstacles. Stopping distance is sometimes lengthened unexpectedly by a driver' sudden delay in cognition and reaction, while the distance headway can be shortened by a driver's impulse so as to shorten the time of the arrival. As a result, traffic accidents occur when the stopping distance becomes greater than the driver's distance headway. Therefore it is important to maintain greater headways than suddenly lengthening stopping distances. However, there are many drivers who maintain an insufficient headway. One of the main reasons is that they do not have any objective evaluation method for safe driving. In this study, the authors suggested the new evaluation method for safe driving instead of the collision prone index (CPI).
