Abstract

Unsignalized intersections are a common scenario in urban areas. Therefore, it is necessary to consider decisions at unsignalized intersections. Left-turn behavior is used as a representative because there are more cases of interactions with other traffic participants under left-turn behavior. First, the paper proposes a way to improve the efficiency and comfort of the host vehicle when the intersection is obscured. Second, a dynamic game theory is proposed based on the potential conflict area of the intersection, considering safety and traffic efficiency. An estimation of the aggressiveness model based on the potential conflict area is proposed. Thirdly, a driving scheme is proposed by adjusting the passing scheme when the game is yielding. Finally, it was simulated for validation at unsignalized intersections by VTD (Virtual Test Drive). Simulation results show that the proposed method can balance comfort and passing efficiency through unsignalized intersections in the presence of occlusion. The average speed of the proposed method through the intersection is higher when interacting with traffic participants.

自动驾驶决策对无信号交叉路口左转行为的影响

无信号交叉路口是城市地区的常见情况。因此，有必要考虑非信号灯路口的决策。本文以左转行为为代表，因为在左转行为中与其他交通参与者发生交互的情况较多。首先，本文提出了一种在交叉路口被遮挡时提高主车效率和舒适度的方法。其次，基于交叉路口的潜在冲突区域，考虑到安全和交通效率，提出了一种动态博弈理论。提出了基于潜在冲突区域的攻击性模型估计。第三，通过调整博弈让行时的通过方案，提出驾驶方案。最后，通过 VTD（虚拟试车）在无信号交叉路口进行了模拟验证。模拟结果表明，在有遮挡的情况下，所提出的方法可以在通过无信号交叉路口时兼顾舒适性和通过效率。在与交通参与者互动时，拟议方法通过交叉路口的平均速度更高。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
