Reliability-Based Highway Geometric Design

Highway collisions are generally attributed to the failure of one or more of the three elements of the highway system: the road itself, the vehicle, and the road user. However, with driver error being blamed for 90-95% of collisions, a strong emphasis has been placed on education and enforcement initiatives with relatively little success. On the other hand, comparatively very little effort has been directed towards reducing driver error and managing driver behaviour through improving the highway geometric design. Highway geometric design involves the proper dimensioning and coordination of the different design elements. Despite the continuous evolvement of the design guidelines since the introduction of motorized vehicles and paved roads in the early 1900s, the fundamentals have not considerably changed.
