Pavement widening on road curves

Pavement widening on horizontal curves is necessary in order to ensure enough lateral clearance between two vehicles which are passing each other on the road curve in order to ensure undisturbed traffic flow. Guidelines and regulations of different countries offer different solutions for determining amount of traffic-lane widening on road curves. This paper shows the analysis of Croatian, Austrian, German and Swiss guidelines. Based on this analysis the optimum proposition for determining the required amount of traffic-lane widening on road curves has been offered.
