The main objective of this research is to identify how terrain and geometric alignment impact on the occurrence of fatigue related crashes in New Zealand and their relationship to location and terrain. A review of the plots for the location of the crash clusters indicates a good correlation between the location of reported fatigue related crashes and the influence of terrain. The research indicates that approximately 80 per cent of crash clusters are located in areas of low demand. Furthermore between 45 and 65 per cent of all crashes have occurred in a location where the driver has travelled from a higher demand (load) area to a lower demand (unload) area.
