Effects of lane width and posted speed limit on speed selection behaviour of drivers
Driving speed is a critical factor in road traffic crashes. Empirical evidence suggests that narrow roads and narrow lanes on roads lead to drivers selecting slower speeds. A program of study has been designed to examine the relationship between roadway design parameters and speed selection among drivers using both a driving simulator experiment in the QUT CARRS-Q advanced driving simulator and an observational study. The key research aim is to examine speed selection behavior of drivers in response to geometric feature changes.
