Driver State Monitoring (DSM) is paramount for improving driving safety for both drivers of ego-vehicles and their surrounding road users, increasing public trust, and supporting the transition to autonomous driving. This paper introduces a Transformer-based classifier for DSM using an in-vehicle camera capturing raw Bayer images. Compared to traditional RGB images, we opt for the original Bayer data, further employing a Transformer-based classification algorithm. Experimental results prove that the accuracy of the Bayer Color-filled type images is only 0.61% lower than that of RGB images. Additionally, the performance of Bayer data is closely comparable to RGB images for DSM purposes. However, utilizing Bayer data can offer potential advantages, including reduced camera costs, lower energy consumption, and shortened Image Signal Processing (ISP) time. These benefits will enhance the efficacy of DSM systems and promote their widespread adoption. 

In this paper, we examine the problem of the Dilemma Zone (DZ) in depth, weaving together the various influences that span the environment, the ego-vehicle, and ultimately the characteristics of the driver. Driver behavior in dilemma zone situations is crucial, and more research is urgently needed in this area. The journey through various modeling approaches and data acquisition techniques sheds new light on driver behavior within the dilemma zone context. Our thorough examination of the current research landscape has revealed that several significant areas remain overlooked. As well as the dynamic impact of vehicles, vehicle interactions, and a strong tendency to over-rely on infrastructure information, there are also concerns about the lack of comprehensive evaluation tools. However, we do not see these gaps as stumbling blocks, but rather as steppingstones for future research opportunities. A more focused study of cooperative solutions is required considering the potential of personalized modeling, the untapped power of machine learning techniques, and the importance of personalized modeling. It is our hope that by embracing innovative approaches that can capture and simulate personalized behavioral data using “everything-in-the-loop” simulations, future research endeavors will be guided. To effectively mitigate the DZ problem, we also point out the research gaps and opportunities for further research in the DZ. 

The emergence of vehicle-to-everything (V2X) technology offers new insights into intersection management. This, however, has also presented new challenges, such as the need to understand and model the interactions of traffic participants, including their competition and cooperation behaviors. Game theory has been widely adopted to study rationally selfish or cooperative behaviors during interactions and has been applied to advanced intersection management. In this paper, we review the application of game theory to intersection management and sort out relevant studies under various levels of intelligence and connectivity. First, the problem of urban intersection management and its challenges are briefly introduced. The basic elements of game theory specifically for intersection applications are then summarized. Next, we present the game-theoretic models and solutions that have been applied to intersection management. Finally, the limitations and potential opportunities for subsequent studies within the game-theoretic application to intersection management are discussed.
