For quite a long time it has been assumed that there is a “grey area” between passenger and goods traffic, which has not been currently recorded by the statistics and also has been assigned partially wrong. It concerns traffic with vehicles with which both goods and passenger transport can be executed (in particular combination vehicles, vans), and with those vehicles that are classified as delivery vehicles, but are used primary for services (e.g. handcraft) instead of commercial goods transport. It was needed to provide a research in this field.
