The aim of this project has been to go through available data for further developing the freight model in Norway on national and regional level, and identify needs for future data collections. Register data from SSB are available at more detailed level than recommended used in regional freight models. The main missing data is information about delivery pattern. This can be obtained for use in regional models from extractions from transport operators data systems. The main problem is to get a covering picture, caused by the high amount of small enterprises, not expected to have their own data systems. Another problem is to catch transports on own account. Related to a locistic module there are missing data about consignment size and volumes through internal warehouses. This information in addition to delivery pattern (at national level) and improved information about transport costs can be obtained from a commodity flow survey. The main drawback of such a survey is the high level of costs related to carry it through with a sufficient level of quality.
