A BASIC STUDY ON SAFE CAR-FOLLOWING DISTANCE --REPORT OF THE NATIONAL RESEARCH INSTITUTE OF POLICE SCIENCE (JAPAN). RESEARCH ON TRAFFIC SAFETY AND REGULATION

This study deals with the characteristics in the recognition of car-following distance by a vehicle driver, and the headway distribution deduced from the car-following distance recognition. The result of the experimental study on the recognition of car-following distance proves that the weber-fechner's law is valid for the relationship between physical car-following distance and the recognition. This fact gives a good reason for the lognormality in a headway distribution. One of the big problems regarding car-following distance is the gap between the mode of the lognormal distribution and the psychologically optimum car-following distance. In order to lessen this gap, safety education or campaign would be useful to change the values of the parameters of the logarithmic function in car-following distance recognition.(a) for the covering abstract of this journal issue see IRRD 813939.
