Outline of Final Research Achievements

This study is aimed at analyzing the influence of take-over request to the human drives issued by the system of autonomous vehicle and the impact of autonomous vehicle upon both safety and efficiency of traffic flow under the mixed situation of manually driving vehicles and autonomous ones. According to the individual car-following analysis, a vehicle that can smoothly react toward the change in relative speed with the preceding vehicle is expected to mitigate the speed reduction of traffic flow. According to the in-laboratory experiment using driving simulator, the take-over request at level 3 of autonomous vehicle does not necessarily give any impact to the productivity of the second task which the drivers are allowed to do. Focusing on the comparative analysis between with and without second task, it is confirmed that the take-over request issued in the case of with-second task may lead to the decrease in time to steer but the increase in breaking strength.

Academic Significance and Societal Importance of the Research Achievements

自動運転車の導入により,道路交通における安全面や混雑,あるいは,交通弱者の問題などの解決に繋がるとの期待があり,自動運転に期待する向きも大きい.その一方,交通工学的観点から見た自動運転車の効果については,必ずしも定見が示されてはいない.本研究では,自動運転と手動運転の切り替えの影響を実証的に分析しつつ,それを踏まえて自動運転車と手動運転車の混在状況下において,自動運転車が交通流の安全性・効率性に及ぼすポテンシャルについて分析を行う.これらの一連の研究成果は,交通工学的に望ましい自動運転のあり方について検討するための重要な基礎情報となり得る.
