One road safety management program is delivered through road planning and engineering, aimed to improve the road design features to reduce the frequency and/or severity of collisions.

There are several problems with the two approaches to deliver road safety. First, deteriorating quality and quantity of collision data, necessary for safety analysis, is jeopardizing the success of reactive safety management programs. Secondly, the inherent nature of a reactive program is problematic (i.e., allowing problems to emerge before treatment) and that the area of influence is limited, responding only to the most problematic locations.
