National travel surveys are collected in a large number of European countries. This data, if harmonised, could provide useful insights into travel patterns of European citizens and help inform infrastructure provision and policy development, particularly in the area of encouraging sustainable mobility and intermodality. Thirty European countries, including the EU27, were surveyed to identify what travel data is collected with which methods. There is a considerable degree of variation between the types of data collected by NTS across European countries. It has, however, been possible to identify some common trends across the collection of national travel surveys in terms of trip purposes and modes. The research, has received funding from the European Union's Seventh Framework Programme (FP7/2007-2013) under the project OPTIMISM, grant agreement n° 284892.
