Risico-onderzoek verkeersdeelnemers in Nederland (ROVIN) : interim-rapport over het deelonderzoek naar de invloed van non-response op de uitkomsten van het CBS-onderzoek Verplaatsingsgedrag.

The Interim report on the National Traffic Survey is presented. As many as possible of the more than 30% non respondents from the survey were interviewed to see if this group had a different travel pattern from the responding group. Differences should regard age, degree of urbanization, household size etc. There was almost no difference in the respondents and the later-on interviewed for these parameters. Only in the transport mode ownership was a significant difference.
