Study title

Despite clear objectives to reduce greenhouse gas (GHG) emissions from road transport, relatively widespread agreements on how land use and transport systems ought to be developed to achieve this, and public control of the most important means, the built environment is continuously being developed in ways contributing to increasing traffic volumes and GHG emissions. This project took as point of departure that lack of empirical documentation of how some combinations of land use and transport-system developme nts affect traffic volumes is an important factor (among others) explaining the gap between goals and reality. The aim was to contribute to change this situation by documenting effects on traffic volumes and GHG emissions of three particularly relevant and complex issues in urban planning: 1) polycentric workplace locations, 2) relocation of warehouses (for freight transport) within the urban region, and 3) urban road capacity expansions. A survey was collected among employees at workplaces located at different distances from Oslo. The questions mainly concerned how employees travel to and from work, as well as whether those who have changed jobs or residences travel differently to and from the current workplace than they did in a previous situation when the workplace or residence was located elsewhere.
