The aim of the thesis is to obtain a better understanding of the importance of parks for urban quality, particularly for safety. This is achieved in two ways; first, by assessing parks’ impact on the perceived quality of the urban environment (whether it is incorporated into housing prices or not) in Stockholm. Second, the study investigates whether safety in parks may be assessed using principles of Crime Prevention through Environmental Design (CPTED) using a high-crime park in Stockholm’s inner city. The thesis starts with an introduction to the theme, with a brief discussion of background theory, literature review, the study area and the methods. Then, it reports the results of the articles included in the thesis and discusses their main contributions to the field of research. A mixed methods approach utilizes both quantitative and qualitative data analysis. Regression models and a Geographic Information System (GIS) were used in Paper I, which aims to clarify how park proximity affects housing prices and, when considering residential properties and park type, how crime rates in parks affect housing prices. Findings show that the further away an apartment is located from a park, the higher the discount on its price effect, but this effect (dependent on the park type), as an accumulated measure of parks, lowers prices or is negligible. Paper II assesses the use and adequacy of CPTED principles to guide the assessment of safety conditions of an urban park. The historical development of CPTED is presented followed by an analysis of a case study, Tantolunden, in Stockholm. Site observations, crime mapping, people count and interviews were conducted. Results show many entrances in this particular park defy the principles of access control and in turn impose limitations on park maintenance. Findings also show that interrupted sight lines create limited surveillance. The paper concludes by identifying the potentialities and challenges of CPTED principles when applied to safety in parks. Findings presented in this thesis are relevant for many stakeholders in society as results show the variation in crime and safety in urban parks, and the way they can be assessed and tackled.
A park is a desirable feature when people are purchasing a property. Buyers are ready to pay more for properties surrounded by natural amenities, such as a pleasant park. However, if a park is targeted by crime and disorder, then it may have a negative effect on people's appraisal. The aim of this study is to reach a better understanding of how parks and crime rates affect housing prices taking into account residential properties and parks type. Stockholm, the capital of Sweden, is used as the case study. The methodology has two stages. An extensive field work was performed in a selected number of parks to help characterize the parks in Stockholm. This information was gathered with secondary data about parks using Geographic Information System. This pre-assessment was later followed by the analysis of 2008s apartment sales using hedonic modelling to assess the effect of parks alone and in combination with crime rates. Results suggest that the effect of parks on prices vary by park type (increased with, e.g. features of cultural and national interest and decreased with ball games or boating facilities) while an aggregated measure of parks lowers overall apartment prices. More interestingly, findings show that the price of apartments tends to be discounted in areas where parks have relatively high rates of violence and vandalism.
Crime prevention through environmental design (CPTED) has long been suggested as a guideline for improving safety in neighborhoods. Yet, little is known about the application of CPTED to urban parks. The aim of this study is to evaluate the adequacy of CPTED principles in guiding the inventory of safety conditions of an urban park. The study begins with a review of the development of CPTED ideas and then focuses on the inspection of a park with a relatively high level of crime in the city of Stockholm, the capital of Sweden. Site observations, parks inspection, crime mapping of police-recorded data, and interviews with selected users and municipal stakeholders underpin the methodology used in this study. Findings indicate that design and management of the park affect the park’s safety conditions—attributes that are easily identifiable when using CPTED as guidance. The article concludes with several general lessons from using CPTED principles to inventory safety in parks.
