With the development of driving automation and entertainment technologies, more and more functions have been embedded into the vehicle cabin. These new functions have brought both opportunities and challenges. As the intelligent cabin can convey both safety-related information and entertainment information to drivers, it is important to consider how drivers’ behaviors may change in the face of these new sources of information. On the other hand, the vehicles become more than a transportation tool, but also a living space. Therefore, cockpit design needs to take both driving safety and ride comfort into consideration. On the other hand, although autonomous driving and driving automation technologies have developed rapidly in past years, it is inevitable that there will be a period when the autonomous vehicles and human-driven vehicles share the road, forming a mixed traffic flow. Therefore, the safety and efficiency of mixed traffic are not only closely related to driving automation technology, but also human-related factors. To address these issues, we have to understand and model the changes of driver behaviors in mixed traffic flow. Therefore, this seminar will review the relevant research conducted by our research group on human-automation interaction both inside vehicle but also in mixed traffic.
