Naturalistic Driving Analysis of Crossing Non-signalized Intersections without Right-of-way

Abstract

An empirical model of driving behavior on a non-signalized intersection without right-of-way was derived through naturalistic driving study. Twenty four intersections were selected for road experiments and ten subjects drove a vehicle on each intersection twice a day for six straight weekdays. The vehicle was well equipped with instruments for measuring and recording both vehicle’s and driver’s behavior. We proposed characteristic variables to describe driver behavior on non-signalized intersections: deceleration starting TTC, deceleration ending point, speed at deceleration ending point, crawling occurrence ratio, crawling distance, crawling period, acceleration starting point, speed at acceleration starting point, and acceleration. Influences on these characteristic values of the following static properties of intersections were tested using ANOVA and multiple regression analysis: turning direction, left sight visibility, and right sight visibility.
