To reduce the risk of vehicular head-on collisions, the Swedish Transport Administration (Trafikverket), has been transforming high traffic-volume conventional roads into barrier separated roads. This process has reduced the number of fatalities by around 80 percent. However, evidence has shown that barrier separated roads degrade quicker than conventional road types. The extent of the problem was quantified by comparing various sets of road surface characteristic data. Comparisons revealed that degradation levels increase by up to 60 percent in the single lane sections of 2+1 type barrier separated roads. Vehicle position surveys were carried out and subsequent data analysis confirmed that confinement of vehicle lateral wander is a main ca...
