Distrubution Center Location Analysis for Nordic Countries by Using Network Optimization Tools
- 2018
-
Reports (other academic/artistic)abstract
- Many supply chain and logistics related location decisions are driven by demand. This paper analyses population densities in Sweden, Finland, Norway and partly Denmark and analyses how a minimum impedance approach would set up the distribution center (DC) locations. For each scenario, travel time maps are generated. Firstly, each country is analyzed separately and 1...5 DC cases are analyzed. Then a merged Nordic area is introduced and a similar approach is used to set up 1…6 DCs. Finally, a sensitivity analysis is conducted to study how the large population of Umeå or Vaasa should be increased in order to make the top five in the Nordic level. The results show distribution centers could be formed in the case of population driven demand products. This also gives insight into how the results can vary when changing perspective from national analysis to Nordic level.

Vägledning för offentliga och privata aktörer vid planering av gränsöverskridande transporter och infrastruktur i Norden
- 2019
-
Reports (other academic/artistic)abstract
- För att utveckla ett internationellt transportstråk, som Blå vägen TET-E12, krävs prioriteringar, kunskap, finansiering och gränsöverskridande internationell samverkan. På nationell nivå hanteras investeringskalkyler och beslut om åtgärder över nationsgränser mer ad hoc än för projekt som är centralt placerade i nationens nätverk. Det gäller samtliga länder i Norden. Aktörer längs stråk som binder samman gränsregioner har därför en mer komplex situation att hantera än andra regionala aktörer. Behovet att bygga en egen regionalt förankrad kompetens inom transportpolitik, transportekonomi, logistik, planering, fastighetsutveckling och data är här betydande. Vägledningen sammanfattar bl.a. erfarenheter från intervjuer med regionala aktörer som arbetat med olika gränsöverskridande projekt i Norden samt företrädare för nationella myndigheter. BA3NET har här arbetat nära INTERREG Botnia-Atlantica projektet ”E12 Atlantica Transport”.

Dissimilarities between the national cost/benefit models of road projects : Comparing appraisals in Nordic countries
- 2020
-
In: Transportation research Interdisciplinary Perspectives. - : Elsevier. - 2590-1982. ; 8
-
Journal article (peer-reviewed)abstract
- The Nordic Council has a vision to create the most integrated region globally by 2030. Nevertheless, Nordic cross-border infrastructure projects are generally developed by each nation individually. Joint Nordic infrastructure planning is thus fragmented. An example of this, as reported herein, is how road projects are assessed by the infrastructure planning authorities in Norway, Sweden, and Finland, the latter to which is included in the comparison for the first time. In each country, cost/benefit analyses (CBAs) are used. In each nation, the monetary values of changes in travel time, accidents, and environmental externalities are estimated. We then apply those values to the three national CBA models to assess an illustrative hypothetical road project. Theoretically, the models should provide similar outcomes when using a common set of parameters. Instead, we show that the choice of national model is crucial to the outcome. The Swedish model, for example, generates a higher cost of travel time than the other models irrespective of the nation from which we choose the parameters. Consequently, CBA-based assessments in the Nordic area depend strongly on the model applied and peculiarities in its coding. Finally, we discuss the policy implications of our findings for appraising national and Nordic projects.

Modelling Changes in Regional Accessibility from Speed Limit Adjustments in the Road Network : A report from the Nordic research project E12 Atlantica BA3NET
- 2019
-
Reports (other academic/artistic)abstract
- The Swedish Transport Administration will adjust the speed limits in the Swedish road network. A point of departure for this adjustment is Vision Zero, a traffic safety project approved by the Swedish Parliament in 1997. The goal of Vision Zero is a radical reduction of the number of fatalities or serious injuries on Swedish roads. However, the suggested new speed limits have given rise to debate and criticism. Regional and local actors have argued that a reduced speed limit may have negative impacts on accessibility and local development. The road network in the Botnia-Atlantica region contains roads where the Transport Administration has suggested reduced speed limits. Sections of the TEN-T E12 road and connecting nearby roads are parts of those roads. The illustrative cases chosen are a part of the E12-region around the city Umeå in Sweden. The purpose of the paper is to present a method for analysis of the distribution of changed accessibility over places, in response to changed speed limit in the road network. The suggested method should be a basis for a dialogue on accessibility and security between local and regional actors on one hand and the Swedish Transport administration on the other. Accessibility although is a multifaceted phenomenon. The impact of changed accessibility on an economy both contains general elements as well as elements of very situation specific character. Given this, the modelling approach suggested make use of three different model approaches; EVA, SAMPERS and PIPOS. The comparison of outcomes from the three models gives an in-depth picture of how changes in speed limits affect accessibility and regional development.
