Key research themes
1. How does passenger presence influence crash risk and safety outcomes among teenage drivers?
This theme investigates the relationship between carrying passengers and the risk of fatal crashes among young drivers, focusing on how passenger characteristics, driver demographics, and time of day affect crash fatality rates. Understanding these associations informs graduated driver licensing programs and tailored interventions to reduce teen driving fatalities.
2. What factors influence passenger perceptions of safety and security in autonomous and conventional passenger vehicles?
This research explores passengers' subjective experiences of traffic safety, in-vehicle security, and emergency management, especially in emerging driverless shuttle buses versus conventional buses. Analyzing gender differences and user acceptance reveals critical psychological and emotional factors vital for mainstreaming autonomous public transport services.
3. What are the advancements and challenges in vehicle occupant detection and safety technologies in passenger vehicles?
The focus here is on technological methods for passenger occupancy estimation and safety enhancement. By comparing invasive and noninvasive occupant detection systems, this theme addresses the implications of occupant detection accuracy on safety features like airbags, as well as challenges posed by environmental factors and vehicle design that affect sensor performance and vehicle safety rating systems.
