Transport generated by residences and workplaces is dependent on the localisation in the city and its surroundings. Not only the transport kilometres but also car ownership and modal split are dependent on the exact location. Knowledge of these dependencies is useful in a planning policy to reduce carbon dioxide emission from traffic. Data from the Danish National Travel Survey is used to analyse transport behaviour of residences and workplaces in the Copenhagen Region up to 100km from the City Centre. Linear regression and logistic regression analyses are carried out on person kilometres, car ownership, and vehicle kilometres etc. dependent on the localisation of the residence together with socio-economic variables. Such analyses are also used on the travel distance, the probability employment, and the vehicle kilometres on the journey to work. The analyses on residences show that the most important parameter is the distance to the city centre. The more central the residence, the lower carbon dioxide emissions will be. A dwelling 28km from central Copenhagen will generate twice as much car traffic as a similar dwelling with the same household in central Copenhagen. Beyond 28km, which is at the edge of the suburbs, the vehicle kilometres are not dependent on the distance to the city. A dwelling in a town with more than 10,000 inhabitants generates 50% more car kilometres than a dwelling at a central location. Localisation in villages and the rural areas increases the environmental impact. Inside the city both person kilometres and car kilometres are lower near a station, areas which are often high density and with shopping centres. Garden cities lead to slightly more person kilometres but less car kilometres than high density areas. The result of the analyses of the location of work places is more complex. A peripheral location results in long distances but so does a central location. The linear regression analysis of the location distance from the city centre together with socioeconomic variables shows no clear location strategy for a reduction of travel distances between work and residence. But analyses on the car kilometres show very clear results. A workplace 29km from Copenhagen City centre generates 3-fold as many car kilometres on travel to work as a workplace in central Copenhagen. A location within 5 minutes walk of a station reduces car kilometres to work by 40% compared with work places farther away from a station. When deciding whether you should give priority to residential areas or business at an actual area, more facts have to be considered. It is considered best to give priority to residential areas in the central areas and to business around the stations. For the covering abstract see ITRD E124693.
