Samenvatting
The first part of this paper describes research activities concerning intermediate cross section roads whose capacity and level of service lies above typical rural roads but below those of the most narrow type of motorway. The range of application of these kind of cross sections is designed for about 12.000 to 18.000 veh /24h.The intermediate cross sections allow easier overtaking in comparison to typical rural roads. The second part deals with special measurements of overtaking slow moving vehicles (farm tractors travelling less than 25 km /h) on rural roads.
