Outline of Final Research Achievements

This study examined the characteristics of the perceived following distance between vehicles when recognizing road rage, the causes of unconscious road rage behavior, and the features of drivers’ perceptions of forward and backward following distances. The results showed that (1) the average perceived following distance at the time of recognizing road rage was approximately 30 meters, and road rage was perceived when the following distance was shorter than the safe following time of 2 seconds; (2) inexperienced drivers had a lower sensitivity to perceiving road rage and were more prone to unconscious road rage behavior; (3) regardless of driving skill, some drivers estimated the forward following distance to be longer than the backward distance, and these factors may contribute to unconscious road rage by following vehicles.

Academic Significance and Societal Importance of the Research Achievements

本研究では，あおり運転の発生には，「あおる側」はもとより「あおられる側」にも問題の起因となる運転行動が存在しており，両者の運転行動や心理状態といったドライバの特徴に着目した対策を講じることが，問題の抜本的な解決につながると考えた。あおり運転が発生するきっかけが，両者の思惑や自車と他車の運転に対する認知度合の差異といった「心のずれ」にあるなら，両者の心理にダイレクトに働きかける解決手法こそが問題の抜本的な解決につながると考えた。そのために，あおり運転時の両ドライバの特徴を抽出し，既存の交通心理学の知見に照し合せて情報のフィードバックおよび共有といった対策を施し衝動的な心理・行動の抑制を狙った。
