A routing tool was developed with the timetable data, which was used in telephone interviews with more than 50,000 people in 2010, 2015 and 2021. The final product is the Microcensus Mobility and Transport (MZMV), the largest survey of the population’s transport behaviour conducted at the national level. Routing with the timetable data improves the data quality in terms of distances travelled and enables evaluations of the collected data according to the categories of long-distance, regional and local transport.
