Samenvatting
There are still gaps in the knowledge of traffic with cycles on rural roads. Therefore attention will be paid to some methodological aspects of traffic due to cycling: 1. the accuracy of a pneumatic- electronic detector;2. the role of "the weather" in the fluctuations of the daily volumes; 3. the margins to take into account when daily volumes are estimated by short visual counts. For this purpose some preliminary research was formulated. This research is in execution now. The design and some previous results are presented here.
