Samenvatting
The paper deals with the description of special measurements of overtaking slow moving vehicles (farm tractors with constant speeds about 25 km /h) on two- lane undivided rural roads. A series of measurements was performed by means of three video cameras and a radar- meter. The results can be used especially considering aspects of traffic safety, road design and level of service, but the results give also answers to some more questions and the opportunity for validating corresponding models.
