The built environment has been manifested to affect walking behavior of individuals. But to what extent and how important are environmental factors in explaining walking activity? Researchers have attempted to identify the relative importance of the different influencing factors on people’s physical activity behavior. That is to what extend activity patterns are explained by individual factors and preferences, how much is explained by social, political and cultural factors and how much is explained by the attributes of the built environment. An early study of Giles‐Corti and Donovan (2003) conclude that How important are the
different factors in explaining walking behavior?
individual and social factors outweigh environmental factors in a relative importance, but the results show nonetheless a significant importance of the built environment (Giles‐Corti & Donovan, 2003). Although, it has been said that it is premature to say that individual and social factors play a larger role than the environment in influencing physical activity, because the two prior factors have been researched for a longer time and there is more known about them than the latter one (Owen, Humpel, Leslie, Bauman, & Sallis, 2004). Environmental factors also differ in importance according to the context and what is particularly being investigated. For example the social factors is far more important for teenagers than for adults and the environment then play a smaller role in comparison (Thompson, 2013).
There are also more diverse environmental factors thought to influence recreational walking than transportation walking (Saelens, Sallis, & Frank, 2003). So it is clear that the environment play a part in all of this but it is impossible to say in general to what degree. This has been argued in a recent critical appraisal and the reason said to be that the quality of walkability studies varies a lot (Gebel, Bauman, & Petticrew, 2007).
The focus of the various literatures contributing to the understanding of the issue has clearly been changing over a short period of time. Research has noticeably evolved towards considering walking as a more complex phenomenon than previously thought, being influenced by factors of different genre, interpersonal and intrapersonal. The environmental factors operate at different scales and levels, influencing walking from regional and city level down to detailed level of streets and parks and even individual gardens (Thompson, 2013).
To help out understanding the context of the environment as an influencing factor on people’s behavior, so called ecological models have been developed and increasingly applied to walkability studies. These models aim at understanding the individual within a complex context where it recognizes the many forces shaping the individual´s behavior and health. The forces span from psychological and social situation up to environmental and policy level, where each of those can affect human well‐being directly or indirectly (Sallis, Owen, & Fisher, 2008; Barton & Grant, 2006; Thompson, 2013).
The following illustrated model is developed by Barton and Grant (2006) and is called the health map. It shows the individual as the heart of the model and recognizes therefore personal differences in desires, experiences and needs in relation to the environment. Interestingly, the focus of research has for a long time been on the more proximal factors to the individual in the model as influencing behavior; that is individual and intrapersonal factors such as age, sex, socioeconomic status, educational level, attitudes and beliefs. Only recently more distal factors to the individual in the model, such as the built environment, have been realized to have more influence than previously believed (Barton & Grant, 2006). This is partly the reason for increased focus on the environment as an influencing factor on walking.
Ecological models can help explaining how behavior is conducted by interaction across levels of influences Environmental factors have been manifested to influence walking behavior but differ in importance according to the context
