Data Processing

In the data processing, the category Other/Unknown is not used. The coder tries to make an as good as possible estimate, or rings the respondent. In this process the journeys of the entire household are involved, so that an as consistent possible picture is provided. For some questions, if an answer has not been filled in, such as an arrival time, a calculated guess is filled in. This is based on the time of departure, an average speed of the relevant mode of transport, and a time of departure of any following journey.
