Abstract

Engineering safety on the road has been a major concern of road safety professionals for decades. Road safety engineering focuses on the interaction between the driver and the road environment. No engineering safety measure is complete without assessing the driver element. It is challenging to predict how drivers will react in different circumstances, as every driver or participant in the road environment (pedestrian, cyclist, etc.) will react in different ways. Engineering measures seek to make people react safely, whether this is reducing speed, slowing down at an intersection, being aware of signage, and so on. In this chapter, we attempt to outline the linkages between road safety engineering, geography, and spatial analysis. Many studies of road safety engineering measures are limited by methodological flaws, such as failure to account for “regression-to-mean” associated with the treatment of high-collision locations and reliance on simple before-and-after measurements without suitable controls.
