Driving Simulator Validation for Nighttime Construction Work Zone Devices

Research was conducted to ascertain the validity of a driving simulator in determining the effectiveness of temporary traffic control devices in a work zone at night. The research was conducted through a field study and a simulator study. The field study examined speeds at six sites. The simulator study involved 127 human subjects. Spot speeds were observed at three locations in a freeway work zone. Locations of the speed studies were at the beginning of the work zone near the transition area, in the middle of the work zone, and at the end of the work zone near the downstream taper. Statistical analyses were conducted to determine whether participants of the study performed differently in the simulator, compared with in the field. Research results established that because of the motorist’s perceived risk of work zones, driving simulators may not replicate mean speeds observed in the field.
