The higher density in our cities requires the effective usage of urban space. Italso demands that health requirements form part of the planning process sincephysical inactivity today is classified as a public health issue. In addition, it hasbeen shown that the denser city and a hurried lifestyle causes mental illness.It is proven that there is a link between the built environment and humanphysical and mental health. In order to promote health in the urban context andthus deal with health- and space related issues, needs knowledge regardingthe influence of the built environment on public health.Demarcation of this thesis includes commuters by bike. Thus, the target groupis chosen with respect to the bike as a space saving and also health promotingmode of transport.The main purpose of this thesis is to contribute to health promoting urbanplanning. Thus the purpose is to translate the definition of health into termsof urban form; to develop a theoretical framework highlighting the connectionbetween them. Furthermore, this thesis aims to, from a basis of this framework,develop a model for investigation of the influence of urban form on the cyclist´shealth and thus assist with a health-promoting tool.The thesis includes a theoretical and an investigative part. The theoreticalpart has included comprehensive literature studies examining the influence ofurban form on the cyclist´s physical and mental health.The investigative part is a workshop undertaken by the undersigned withparticipants from Nacka kommun and Stockholms stad stadsbyggnadskontor.The purpose was to test the model as a process- and assessment tool.The result of this thesis indicates that physical and mental health is mergedthrough urban form. Furthermore, strategies promoting effective commuting bybike seem to play a central role in the current planning process. Also, in termsof prerequisites for health promoting urban planning, it has been shown thatthere are differences between inner city and suburban areas.Altogether, this piece of work highlights the importance of the awareness thaturban form has on health. The work, particularly the model, constitutes a firststep towards methodology development and thus encourages further studiesin this relatively unexplored interdisciplinary field.
