Influences of job and household location on commuting distances and travel modes in
urban regionsExperiences from the Copenhagen region and other Nordic urban areas
Petter NæssProfessor in Urban Planning at Aalborg Universitywith part-time positions at Oslo University College and Institute of
Transport Economics
Differences in our approach compared to mainstream research
• Drawing on theories of urban planning, transport geography and mobility sociology, not only transport economics
• Aiming at explaining causal mechanisms by which urban form influences travel
• Combining qualitative and quantitative research methods
• Emphasis on being aware of the basic assumptions of the studies, seen from a philosophy of science perspective
The Copenhagen Metropolitan Area study of relationships between residential location and travel
• Fairly representative samples, but persons with a high education are overrepresented
Residential location and commuting distances
Rationales for choosing among job locations• Distance limitation (in terms of geographical distance as well
as in terms of travel time), which may be grounded in several considerations: – saving time
– saving money
– bodily constraints, e.g. in one’s fitness for walking and biking
• A wish of being able to choose the best job opportunity (in terms of salary, working conditions, self-realization, etc.)
Conditions contributing to:High priority attached to choosing the best facility:
• Specialized job skills• Few domestic obligations• High mobility resources• Many facilities available in the
local area of the dwelling, enabling residents to choose
• Short distance from the local facilities to the closest competing concentration of facilities
High priority attached to distance minimizing:
• Non-specialized job skills• Many domestic obligations• Low mobility resources• Few facilities available in the
local area of the dwelling, restricting residents’possibilities for choice
• Long distance from the local facilities to the closest competing concentration of facilities

A clear center-periphery gradient in commuting distances has also been found found in Oslo, Helsinki, Århus, Hangzhou and a number of other cities worldwide
Residential location and travel modes for journeys to work
Gender differences in the influences of residential location on commuting
A similar pattern was found in Oslo, Norway and in Hangzhou, China
Workplace location and commuting distances
Workplace location and travel modes for journeys to work
Oslo, mainly office workplaces
Similar results found in Copenhagen and Trondheim (strong center-periphery gradient), Århus, Aalborg and Odense (weaker effects)
Are cities doomed to sprawl?Oslo – an example of the opposite
