This thesis aims to develop a methodological framework for analyzing the accessibility to potential social utility environments within urban green spaces from a broad population spectrum within a weekday context. The thesis departs with a scientific literature review, which investigates what types of social utilities urban green spaces potentially can provide to an urban population and what kind of attributes that are important for each utility. The review revealed three main utilities derivable from urban green space; stimulation pf physical activity, mental recovery and social interaction. Important aspects and theoretical concepts of accessibility within a weekday context were also investigated. From these findings, a methodological framework was constructed that first classifies all urban green spaces within the case area quantitatively according to their potential to provide these three main utilities. As urban green space attribute data, a sociotopic classification is used, along with area size and traffic noise pollution. Then, walking accessibility from residential areas to these types of social utility areas for each utility is analyzed. Population statistics is also connected to the accessibility level data. This methodological framework was then applied on this study’s case area, the city of Gothenburg. The result revealed that the most common form of utility within Gothenburg is social interaction, followed by stimulation of physical activity. The result indicated that a majority of the population within the study area have an adequate accessibility to these forms of utility, while only a third of the population had it to mental recovery, which also appear to be the generally most desired utility. The main reason for a lack of accessibility to these utilities were lack of larger urban green spaces in the vicinity of residential areas and traffic noise. From these results, four main conclusions were derived. Firstly, urban green spaces are not a homogenous resource. Secondly, accessibility is a key concept in the understanding of urban green space utility potential for urban inhabitants. Thirdly, to quantitatively analyze accessibility to social utilities within urban green space is a complicated process that requires a lot of data. Fourthly, despite several shortcomings, the methodological framework developed in this thesis can reveal important obstacles for the strive towards social sustainable urban environments.
Efterfrågan på arbetsplatsparkering - En systematisk forskningsöversikt av styrmedels effekter

This study is a systematic literature review paper which aims to present an overview over the last years research in the EU, Norway and Switzerland that deals with workplace parking. This has been done with a systematic search through the scientific search engines Scopus and Google Scholar. The keyword phrase used was “workplace AND parking”. Ten peer reviewed articles were found using predetermined criterias and two articles were qualified from reference lists. The theoretical framework used has been about sustainable development, sustainable mobility and five categories of management control measures. The results show that regulation of workplace parking supply and fees are the most discussed methods. Within these two, supply management is most effective by itself but combining the two might be even more effective. When using parking fees, what matters a lot is how often you have to pay. Paying every day or by the hour is a lot more effective in reducing car use than if monthly payment is used. The category of instruments that was discussed the most was “taxes and fees” while only one article was about “technical solutions”. An important conclusion is that combining different interventions is preferable to reach sustainable mobility. The last years research comes from a very concentrated part of Europe and is made mostly using quantitative method which is why focus now should lie on diversifying research to reach more accurate conclusions.
