Abstract
The main objective of the Groningen TSM-scheme, viz the restraint of motor car traffic in the city centre, has materialised in a decrease of 47% in car traffic volumes. The accessibility by car, however, was only slightly reduced. The indirect effects of the scheme are generally less than the physical results. There have been a number of trends: during the first year of implementation shopkeepers tended to postpone their investments while later on they decided to start investment again. There have been, however, a considerable number of changes in the operating results of the retail trade. There should be a possibility of settlement of damages caused by TSM-schemes.
