I have a report on driver behaviour in a road tunnel under different driving conditions (smoke, fire suppression systems, lighting). The study was based on experiments using a virtual reality set-up. If you want to study driver's behaviour for a risky traffic situation such as overtaking, you'll probably have to rely on virtual reality. This study is complete, but the full report (German only) has not been made publicly available.
Sorry, I don't have an English translation or an original English reference. You may try Google Translator or some similar online tool. The pdf file describes the virtual reality set-up with little Detail. It may be helpful as it refers to selected software and hardware components.
