Night vision enhancement systems (NVESs) have been developed to improve visibility at night through supplementing drivers' direct vision with additional information shown on a display, rather than replacing drivers' direct vision. Existing studies have shown that NVESs may increase recognition distance, but may also increase drivers' mental and visual distraction (eyes-off-road). Each scan of the display of the night vision enhancement system involves some visual and mental cost to the driver. This research focuses on developing an affordable and integrated experimental platform that can provide drivers using NVESs with a realistic nighttime driving experience. Study on both near-infrared (NIR) and far-infrared (FIR) NVESs' overall benefits and driver distraction were conducted on this platform with the purpose of exploring both the advantages and disadvantages of current NVESs and making recommendation for future improvements. Twenty-four experienced drivers from Northeastern University (staff and students) participated in this study of NVESs. They used and tested NVESs systems in the Virtual Environments Laboratory and were required to complete two experimental trials, each individually. Results demonstrated that simulation provides a good opportunity to experience driving with a NVES, and also is a very good tool for conducting research on NVESs, especially in adverse weather conditions like fog.
