Relationship between Composition Pattern of District Road and Driving Behavior using ETC2.0 Probe Data

Abstract

In this study, we focused on the front/rear acceleration that occurs in the sudden deceleration behavior of automobiles, defined the near-miss rate as a safety evaluation index, and clarified the influence of the composition pattern of district road on driving behavior. The results showed that longer link lengths increase safety, and that although the composition pattern of district road is basically hazardous, the effect of the hazardousness depends on the characteristics of automobile trips and the mixing ratio of composition pattern of district road. Quantitatively, the results also suggest that a cul-de-sac and loop pattern are relatively safe composition patterns that are effective in reducing the increase in the near-miss rate because their special shapes eliminate through traffic and only residents of the homes connected to the link are basically passing through.
