Abstract
The relationship between near-miss incidents, as a substitute characteristic for traffic accidents, and driver behavior indexes was made clear in order to develop a method of quantitatively assessing safe driver behavior based on accident risk. Several driver behavior indexes were first formulated from actual accident circumstances, focusing on crossing-path accidents at stop sign intersections, which frequently occur in Japan. Using a naturalistic driving database, driver behavior indexes correlated with near-miss incidents were then identified. The indexes were then validated by conducting driving tests in a proving ground to clarify the respective mechanism leading from such driver behavior to near-miss incidents.
