Utmaningar och hinder i gränsöverskridande transportinfrastrukturplanering : En studie av TEN-T med Nordiska triangeln som exempel / Challenges and Obstacles in Cross-border Transport Infrastructure Planning : A Study of the TEN-T and the Nordic Triangle

Remmo, Johannes January 2012 (has links)
Flera saknade länkar i Europas transportnät definierades på mitten av 1980-talet som nödvändiga att bygga för att bidra till att uppnå de EU-politiska målen om fri rörlighet inom gemenskapen, större och jämnare transportflöden inom och mellan medlemsstaterna, ekonomisk tillväxt, en friktionsfri och välfungerande inre marknad, hållbar utveckling samt territoriell, social och ekonomisk sammanhållning. EU och medlemsstaterna initierade mot denna bakgrund transportinfrastrukturprogrammet "Trans-European Networks for Transport", eller det transeuropeiska transportnätverket (TEN-T) på svenska, som en följd av Maastrichtfördraget 1992. I Norden ska den s.k. Nordiska triangeln, som både har pekats ut som ett särskilt prioriterat transportinfrastrukturprojekt i de nu gällande och sannolikt inom kort i de nya EU-riktlinjerna för TEN-T, bidra till att uppnå de ovanstående politiska målen. Syftet med projektet är att sammanbinda Norge, Sverige, Danmark och Finland via uppgraderade och gränsöverskridande vägar, järnvägar och maritim infrastruktur. Förutom att projektet anses förbättra förbindelserna för gods och passagerare inom Norden, skapas bättre möjligheter för större och snabbare transportflöden till och från Centraleuropa, Ryssland och de baltiska länderna. Det västra benet i den Nordiska triangeln, dvs. korridoren Oslo-Göteborg-Köpenhamn, har varit föremål för diskussion sedan 1980-talet då en högklassig motorväg, järnväg samt en fast förbindelse över eller under Öresund och Fehmarn Bält föreslogs av "European Round Table of Industrialists". Syftet med infrastrukturpaketet var att förbättra transportinfrastrukturen inom korridoren samt få en fast förbindelse till kontinenten. Merparten av paketet har genomförts men en del kvarstår, däribland uppgraderingen av järnvägen, vars planläggning försvåras av det faktum att nationsgränserna medför utmaningar och hinder mot ett förverkligande av detta gränsöverskridande projekt. Syftet med uppsatsen har varit att identifiera och analysera dessa utmaningar och hinder, liksom att ge underlag för förslag i effektiv hantering och motverkan. Med utgångspunkt i institutionell teori och i transaktionskostnadsteori har studien visat att bristen på samordning och internationalisering i transportinfrastrukturplaneringen, med stor sannolikhet, utgör centrala faktorer i förklaringen till varför de tre berörda skandinaviska länderna sedan 1980-talet inte har realiserat en sammanhängande och av alla parter upplevd högklassig järnväg. För att kunna motverka och hantera dessa utmaningar och hinder på ett effektivt sätt bör Norge, Sverige och Danmark överväga att ta större hänsyn till gränsöverskridande infrastrukturplanering i framtida organisations- och styrmodeller för transportinfrastruktursektorn. Anledningen är att den nuvarande institutionella ramen för tillhandahållandet av transportinfrastruktur, förefaller ge upphov till höga transaktionskostnader som försvårar och förhindrar effektiv planering på inter-/multinationell nivå. Ett faktum som kan leda till att eventuellt nödvändig och lönsam transportinfrastruktur inte byggs. En organisatorisk lösning som diskuteras i uppsatsen, och som kan reducera dessa transaktionskostnader, är bildandet av ett Skandinaviskt Trafikverk med internationaliserade och harmoniserade planeringsprocesser. / A number of missing links in the European transport network was, during the mid 1980ies, defined as crucial for the smooth functioning of the internal market, and for ensuring sustainable development, economic growth, improved accessibility as well as economic, social and territorial cohesion. This lead in 1992 to the inclusion of a specific legal basis for the "Trans-European Networks for Transport" (TEN-T) in the Maastricht Treaty. The Nordic Triangle has, since the initiation of TEN-T in 1992, been considered as a priority transport infrastructure project. This is stated in the current and in the proposal for new EU-guidelines for TEN-T. The aim of the project is to contribute to the achievement of the above-mentioned political goals by building and upgrading roads, railways and maritime infrastructure between the Nordic countries. This is thought to improve the passenger and freight transports within the Nordic region but also to central Europe, the Baltic countries and Russia. The western leg of the Nordic Triangle, i.e. the corridor Oslo-Gothenburg-Copenhagen, has been of interest since the 1980s when a continuous motorway, high-speed railways and fixed links over/under the Oresund and the Fehmarn Belt were proposed by the European Round Table of Industrialists. The aim of the infrastructure package was to improve the transport infrastructure in the corridor, and via the above-mentioned tunnel/bridge projects, receive fixed links to central Europe. The majority of these plans have been implemented but some remain unrealized, including the railways, whose planning is complicated by the fact that the national borders poses challenges and obstacles to the realization of this cross-border infrastructure project. The aim of this paper has been to identify and analyze these challenges and obstacles, and provide proposals on how to restrain and mitigate them. Based on institutional theory and transaction cost theory it was found that the lack of coordination and internationalization in transport infrastructure planning, are two key factors, that explains why the countries in question have not managed to plan and build a continuous and sufficient railway. In order to restrain and mitigate these challenges and obstacles in an efficient way, one must consider to take greater account of cross-border planning in organizational and governance models for the transport infrastructure sector. The fact that the current institutional framework for the provision of transport infrastructure seems to give rise to high transaction costs, that impede or prevent efficient cross-border planning, makes this reasoning even more relevant. An organizational solution that is discussed is the formation of a transnational Scandinavian Transport Administration.

Transport infrastructure: making more sustainable decisions for noise reduction

Oltean-Dumbrava, Crina, Watts, Gregory R., Miah, Abdul H.S. January 2013 (has links)
There is a global and growing sustainability agenda for surface transport yet there are no specific means of assessing the relative sustainability of infrastructure equipment. Transport noise reduction devices are a significant part of the surface transport infrastructure: they specifically address environmental and social needs, have a high economic impact, and involve a wide range of raw materials raising multiple technical issues. The paper presents an account of the bespoke tool developed for assessing the sustainability of transport noise reduction devices. Regulatory standards for noise reduction devices and the relevant sustainability assessment tools and procedures adopted worldwide were reviewed in order to produce a set of pertinent sustainability criteria and indicators for NRDs projects, which were reviewed and edited during a stakeholder engagement process. A decision making process for assessing the relative sustainability of noise reduction devices was formulated following the review of the literature. Two key stages were identified: (1) collection of data for criteria fulfillment evaluation and (2) multi-criteria analysis for assessing the sustainability of noise reduction devices. Appropriate tools and methods for achieving both objectives are recommended.

Využití PPP při výstavbě dopravní infrastruktury / The Usability of PPP projects in the Transport Infrastructure

Šimurdová, Pavlína January 2009 (has links)
The diploma thesis evaluates the topical situation regarding PPP projects (Public Private Partnership) in the Czech Republic. The definition of the PPP project together with advantages and disadvantages of this concept and the explanation of the PPP process can be found in the first chapter. Second part is mostly focused on the description of the transport infrastructure in Czech and its possible expansion determined by the usage of PPP projects. The crucial part of the third section is the analysis of the already executed PPP projects -- both on the governmental and municipal level. The implementation of PPP projects in the Czech Republic is also confronted with the situation in the Visegrad countries and Russia.

Småhusfastigheters värdeförändring vid större infrastrukturprojekt : En studie av ombyggnationen E4 Sundsvall

Andersson Skått, Kristian, Bergkvist, Kristoffer January 2019 (has links)
Infrastruktursatsningar är en stor del av den regionala utvecklingen i Sverige och forskare i ämnet är eniga om att satsningar på infrastruktur genererar en ökad ekonomisk utveckling. Något de fortfarande är oeniga om, är vilka metoder som är lämpliga att använda för att räkna ut effekten av den ekonomiska vinsten. Finns det några som gynnas mer än andra eller till och med missgynnas av dessa infrastrukturprojekt, hur ser det till exempel ut på landsbygden i de samhällen där större vägar tidigare passerat. Har dessa samhällen gynnats av att ha snabbare och enklare pendling till staden, eller har de istället drabbats negativt när motorvägen, som en del livnärde sig på, fått en ny sträcka. Denna forskningsrapport fördjupar sig i en av de största infrastruktursatsningarna i norra Sverige, nämligen ombyggnationen av europaväg 4 (E4) genom Sundsvall. Projektet som pågick mellan år 2010 och 2015 innebar att sträckan från Njurunda i söder till Skönsberg i norr byggdes om samt att Sveriges fjärde längsta bro anlades över Sundsvallsfjärden. Studien har med hjälp av ortsprismetoden och ortsanalyser utvisat vilken värdeförändring som skett på fastigheter taxerade som småhus, vid detta infrastrukturprojekt. Resultatet av dessa studier visar på den genomsnittliga förändringen av fastighetspriser i områdena Njurundabommen, Nedre Haga/Skönsberg, Nolby/Kvissleby samt Västbo. Data som låg till grund för resultatet visar delvis för få transaktioner, vilket är vanligt vid försäljningsanalyser på ortsnivå. Det genererar i sin tur en osäkerhet i resultatet, vilket medför att förändringarna kan bli stora i förhållande till den verkliga försäljningsutvecklingen. I denna studie minimerades detta genom att två likställda områden slogs ihop samt ett område fick tas bort, vilket slutligen gav ett resultat som indikerar på att områdena i denna studie haft en mer negativ prisutveckling mot Sundsvall och Sverige, sedan området fått en ny infrastruktur i form av E4:an Sundsvall. / Infrastructure investments is a large part of the regional development in Sweden, researchers in the subject agrees that investment in infrastructure generate increased economic development, one thing they still share a disagreement in which calculating methods are suitable. Are there any winners or losers in infrastructure projects, for example, smaller cities in the countryside where highways have previously passed, have they benefited from a quicker and easier commuting to the city, or have they been adversely affected when the highway has been given a new stretch? This research report focuses in one of the largest infrastructure investments in northern Sweden, European road 4 (E4) through Sundsvall. The research, combined with location-based sales comparison method and local analyzes, will show what effect market values will have on the houses real estate’s and what influence the road construction might have regarding to the values of the properties. The results of these studies are shown trough the average changes in property prices in the areas of Njurundabommen, Nedre Haga/Skönsberg, Nolby/Kvissleby and Västbo. However, the result was shown to have too few transactions, which is common in local level sales analyzes. This generates uncertainty in the result, meaning that the values can be large in relation to the actual sales development. The uncertainty was minimized in the results by merging two similar areas, which finally gave a result that indicates that the areas in the study had a more negative development towards Sundsvall and Sweden, since the area received a new infrastructure in the form of the E4 Sundsvall.

Modelagem da dinâmica espacial das mudanças na cobertura da terra na região portuária da Baixada Santista. / Spatial dynamics modeling of changes in land cover in port region of Baixada Santista.

Kawashima, Renata Sayuri 08 December 2014 (has links)
Os padrões espaciais das alterações da cobertura da terra podem ser analisados a partir de modelagens da sua dinâmica espacial. Essas modelagens são capazes de descrever possíveis fatores responsáveis pelas mudanças territoriais, bem como viabilizar a estimativa de impactos futuros sobre o ambiente simulado. Considerando as pressões do setor de infraestrutura portuária sobre as configurações da forma de uso e planejamento do espaço na região portuária da Baixada Santista, tais como o aporte por áreas de retroporto, o armazenamento e o transporte de cargas, este estudo buscou desenvolver modelos dinâmicos da paisagem e investigar a relação entre as alterações na cobertura da terra e a infraestrutura de transportes na região portuária da Baixada Santista. A partir de produtos de sensoriamento remoto e da metodologia de modelagem dinâmica espacial baseada em autômatos celulares, foram gerados mapas simulados e cenários de prognósticos, com e sem projetos de expansão portuária para o ano de 2024. Os mapas simulados do ano de 1995 e 2005 foram semelhantes aos mapeamentos temáticos de cobertura da terra reais e apresentaram boa avaliação. Importante ressaltar que, apenas o mapa simulado de 2013 não previu as novas instalações portuárias, mesmo com a simulação rodando com a variável de novos empreendimentos operacionais em curto intervalo de tempo. O modelo estacionário em 2024 mostrou a expansão de áreas construídas em substituição, sobretudo, às áreas de campo. Não houve expansão de novas manchas de áreas construídas e isso condiz com a tendência de expansão de áreas urbanas seguindo as áreas já consolidadas e com infraestrutura implantada. Com relação à geração de modelos com os projetos de expansão portuária, tem-se a implantação de diversos empreendimentos ocupando parte da margem esquerda do estuário e áreas de retroporto próximas do arco viário da Baixada Santista. / Spatial patterns of change in land cover can be analyzed with spatial dynamic models. This modeling can indicate the driving factors of territorial changes as well as assess future impacts over the simulated environment. Considering the pressures of the port infrastructure sector over the land use and physical planning in the region of Baixada Santista, such as the demand for backport areas as well as for loads storage and transport, this study aims to develop dynamic models of the landscape and investigate the relationship between land cover change and the transport infrastructure in the port area of Santos. With the aid of remote sensing products and cellular automata based models, simulated maps of past landscapes and maps of future landscape scenarios were generated, both considering and disregarding port expansion projects for the year 2024.The simulated landscape maps of 1995 and 2005 were similar to the real ones, and hence, presented high fitness indices. It is important to mention that only the simulated map of 2013, could not foresee the new port facilities, even when the runs took into account the variables associated with the new operational ventures in a short period of time. The stationary model showed an expansion of built-up areas, mainly replacing former field areas. There was no occurrence of new patches of built-up areas and this trend is consistent with the expansion of urban areas nearby the already consolidated and established areas disposing of infrastructure facilities. Regarding the generation of future simulated scenarios taking into account the port expansion projects, they could well reproduce the implementation of several projects along part of the left bank of the estuary and nearby areas of the road ring of Baixada Santista.
