- Accessibility plays an essential role in determining real estate prices and land use. An understanding of how accessibility and changes in accessibility influence real estate prices is key to making decisions regarding investments in infrastructure projects. From an accessibility point of view, it is not clear that there should be differences in valuation depending on the mode of public transport, road, or rail. There are, however, other differences that may affect real estate prices differently. For example, railway stations more often than bus stations, tend to be associated with a higher level of service. In addition, an investment in a railway station may signal a long-term decision from the policymaker. A third possible explanation concerns differences in perceived safety, comfort, and security. This paper aims to study if and how capitalization of accessibility differs between modes of transportation. The findings indicate that rail has a higher impact, both for single-family and multifamily houses. The implication of these findings may be of importance for future infrastructure investments and their corresponding cost-benefit analyses. Incorrect valuations of the benefits of infrastructure investments may result in sub-optimal investments.

- This paper is focused on implementation challenges related to the integration of sustainable mobility in strategic local/regional land use and transport planning. The work was based on a case study of Stockholm, Sweden, focusing on four current plans and strategies of key importance for sustainable mobility. We identify and discuss implementation challenges related to sustainable mobility using a theoretical framework from the policy integration literature, with a focus on the dimensions of “layering”, “drift” and “exhaustion” (Rayner & Howlett 2009).The empirical analysis led us to identify a complementary dimension which we call ‘Parallel policy making’. The parallel policy making reflects a fundamental lack of integration of sustainable mobility in policies and plans of strategic importance, which hinders effective policy integration. Altogether, we conclude that a better insight into the practice of parallel policy making is crucial for development of more effective implementation strategies for sustainable mobility in Stockholm and elsewhere.

- The dominant road traffic particle sources are wear particles from the road and tire interface, and from vehicle brake pads. The aim of this work was to investigate the effect of road and brake wear particles on pulmonary function and biomarkers in isolated perfused rat lungs. Particles were sampled from the studded tire wear of three road pavements containing different rock materials in a road simulator; and from the wear of two brake pad materials using a pin-on-disk machine. Isolated rat lungs inhaled the coarse and fine fractions of the sampled particles resulting in an estimated total particle lung dose of 50 μg. The tidal volume (TV) was measured during the particle exposure and the following 50 min. Perfusate and BALF were analyzed for the cytokines TNF, CXCL1 and CCL3. The TV of lungs exposed to rock materials was significantly reduced after 25 min of exposure compared to the controls, for quartzite already after 4 min. The particles of the heavy-duty brake pads had no effect on the TV. Brake particles resulted in a significant elevation of CXCL1 in the perfusate. Brake particles showed significant elevations of all three measured cytokines, and quartzite showed a significant elevation of TNF in BALF. The study shows that the toxic effect on lungs exposed to airborne particles can be investigated using measurements of tidal volume. Furthermore, the study shows that the choice of rock material in road pavements has the potential to affect the toxicity of road wear PM10.

Networked authority and regionalised governance : Public transport, a hierarchy of documents and the anti-hierarchy of authorship

Tidskriftsartikel (refereegranskat)abstract
- This paper is concerned with the authority of written documents and how these artefacts work as governance devices. Networked authority is introduced as a concept to elucidate how documents accumulate formal power in a collaborative process, where several formally independent but informally interdependent organisations together point out the direction of regional public transport planning in the form of one strategic document. Drawing upon recent research on bureaucracy, authority and documents, the paper empirically explores these connections in the context of public transport in Stockholm, Sweden. Based on this case study, authority was found to be accomplished as the written document reproduced an existing hierarchy of documents, through an anti-hierarchical process where the newly formed Regional Public Transport Authority involved several formally independent but informally interdependent organisations, and by lacking a sole author. These three features are crucial for understanding how a collaborative process erodes individuality and personal responsibility, while producing anonymous, networked authority. These results are discussed in relationship to Foucault’s notion of authorship, the author-function, which is derived from legal–institutional networks, much like networked authority. Understanding how networked authority is accomplished through a hierarchy of documents and an anti-hierarchy of authorship contributes with new knowledge on documents and how these work as governance devices in regional governance.

The struggle to achieve holistic landscape planning : Lessons from planning the E6 road route through Tanum World Heritage Site, Sweden

- Since the EU introduced the European Landscape Convention (ELC) in 2000, the landscape has received growing attention in spatial planning and environmental impact assessments. To promote implementation of the ELC, the Swedish National Heritage Board proposed its Landscape Vision 2020, which addresses the goal of a ‘holistic landscape policy’. This study examined challenges and benefits brought by such a holistic approach to handling landscape protection/management within four issues in planning practice, namely cross-sector cooperation, local participation, integrating culture and nature, and bridging past and future. The analysis focused on a controversial road project passing through a World Heritage Site in Sweden. The results showed that the four issues were closely interlinked. In the case study, a new wave of cross-sector cooperation at authority level was observed, but it was also found to dominate the entire planning process and eventually limit the achievement of the other three issues. In conclusion, this study identified institutional culture and political context as key explanatory factors for understanding how the ELC and a holistic landscape view can be implemented in national practice.
