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
• Data collection in 29 residential areas
• Quantitative main survey (1932 respondents)
• Follow-up detailed travel diary survey (273 respondents)
• Qualitative interviews with 17 households
• Fairly representative samples, but persons with a high education are overrepresented

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

A similar pattern was found in Oslo, Norway and in Hangzhou, China

Oslo, mainly office workplaces
Similar results found in Copenhagen and Trondheim (strong center-periphery gradient), Århus, Aalborg and Odense (weaker effects)
