Abstract
The standard designs of rural roads vary a lot and show several failings affecting the road safety negatively. The paper presents some results of a categorization of existing roads. This standardization of road design is believed to identify low volume roads and therefore harmonize the driving behaviour and increase the road safety. Based on empiric analysis road sections were dedicated and evaluated. The new single lane cross section for low volume roads showed positive results. Overall, the results of the project indicate that normalised road characteristics within design classes have positive effects on the driving behaviour and therefore the safety level on roads.
