In Örebro, the car traffic share does not tend to decrease. The crowdedness on some of the bus routes is high at times. Investigations show that the residents of Örebro want a city centre whose street environment is more restrictive of car traffic and better for pedestrians, cyclists and public transport. To decrease the car traffic share a rapid, convenient, clear, effective and environmental friendly public transport with high frequency and strong capacity in a short, direct and logical network is needed. A modern tramway fulfils these criteria. At first, this report describes factors that are important to take into consideration when planning a tramway. Thereafter it comes with – from analysis of, among other things, the population density and travel pattern – suggestions for tramway routes through Örebro. Where more than one conceivable route alternative has been identified, comparisons have been made to illustrate their pros and cons. A big part of the work has been devoted to – after considering the physical condition of the street space – showing problems and possibilities, and coming up with proposals for the design. These are some of the conclusions made by the report (-gatan = the… street, -vägen = the… road):  A good starting point would be "tramwayfication" of the bus routes 1 to 4 and their wickerwork structure.  To avoid a big demand of complementing bus service the mean value of the tramways stop spacing in Örebro should not be bigger than 700 meters.  To give Vivalla an effective and attractive tramway it has to go straight through the area.  A route that goes via the Hedgatan/Kryptongatan intersection, between Baronbackarna and Vivalla centre, would be better than a route passing next to the Vivalla school. This is dependent, however, on new buildings being concentrated to the Vivalla/Lundby passage and the development of Vallby into no more than a low-density residential area.  A route along Malmgatan and Järnvägsgatan would be better than a route along Västra Nobelgatan and Östra Nobelgatan or Kilsgatan and Olaigatan.  Hedgatan between Långgatan and Trängkårsvägen, Västra Nobelgatan between Västerplan and Hertig Karls Allé (including the intersection Västra Nobelgatan/Hertig Karls Allé), Västra Nobelgatan between Lövstagatan and Gustavsgatan, Rudbecksgatan between Trädgårds-gatan and Mogatan, and Åstadalsvägen between Rundstigen and Barkvägen are places that can be tricky when it comes to the construction of a tramway and therefore require specific solutions.  For streets that could be subject to a future tramway, it would be more efficient and more cost effective to adjust the physical environment of the street – the sewage and drainage systems, for example – at the same time as any pre planned routine maintenance.  The housing areas along the current public transport passages should be made more concentrated; especially on those streets which could be subjected to a future tramway.  New constructions that could make the conditions worse for a future tramway should not be started. For example, the parking area in front of the main entrance to the hospital (USÖ) and the area immediately south of the roundabout next to the university should not be built on before plans for a future tramway have been finalised.

Stockholms spårvägar växer i allt snabbare fart, och det är allt fler kommuner som är intresserade av den typen av transportmedel. Något som idag är en brist inom spårvägsindustrin i Stockholm är kunskap och erfarenhet om spårvägsämnet. Drift och underhåll har varit minimal eftersom det inte har prioriterats sedan Tvärbanan öppnades. Detta har lett till för tidig reinvestering av gatuspår i mångmiljonbelopp. Då det förekommer olika förutsättningar som måste tas hänsyn till i form av buller, mån om plats och geoteknik finns det många konstruktioner att välja mellan när en spårväg ska byggas. Denna rapport har som syfte att underlätta val av spårvägsinvesteringar i framtiden. Det har också som mål att bidra med kunskap om hur viktigt det är med drift- och underhåll och att det inte bör snålas in på den aspekten. En begränsning har gjorts till fem spårvägskonstruktioner som förekommer i Stockholm och vanligtvis i Göteborg och Norrköping. För att få en förståelse för hur konstruktionerna är uppbyggda redogörs en beskrivning av dem i rapporten.  Rapporten inleds med hur det historiskt har sett ut med spårvägar, nedläggning av dem och återinvestering i Stockholm. Dessa år av glapp mellan nedläggning och återinvestering i Stockholm visar på hur mycket kunskap som har glömts bort och som måste fås tillbaka för framtida investeringar. En analys kring placering av de olika konstruktionerna, hur varierande för- och nackdelarna och kostnaderna är avslutar rapporten. Mycket av rapporten bygger på litteraturstudier på tidigare rapporter som har kompletterats med kontinuerliga möten med handledare och kontakt med personer från olika kommuner och företag i Sverige för att inhämta trovärdig information. / The tramways of Stockholm are growing at an increasing rate and so is the number of municipals interested in that type of transportation.  In Stockholm’s tramway industry there is currently a lack of knowledge and experience on the subject of tramways. Drift and maintenance has been minimal due to lack of prioritization since Tvärbanan was opened. This has led to a premature reinvestment of millions of SEK for road tracks. Due to different presumptions that have to be taken into account such as noise, considerations of room and geoscience, there are many different constructions to choose from when a tramway is to be built. This report’s purpose serves to facilitate choice of tramway investments in the future. Another goal of the report is to contribute with knowledge of how important service and maintenance of tramways is and why shying away from spending money on these matters is bad. For the purpose of this report a restriction has been made, five tramway constructions will be looked at, these are present in Stockholm but also in Göteborg and Norrköping. To acquire an understanding of how the constructions are built, a description of these is accounted for in the report. The report starts off with a historical perspective on tramways, closure of them and reinvestment of them in Stockholm. The years of gaps between closure and reinvestment in Stockholm shows how much knowledge has been forgotten and has to be reacquired for future investments. In the end of the report an analysis, about placement of the different constructions, how varied the pros and cons are and the costs of these, is presented. Much of the report is based on literature studies of earlier reports and has been complemented with continuous meetings with tutors and contact with people from different municipals and companies in Sweden to obtain trustworthy information.

The bject of these was finding, if tramway transport had to be displaced by trolley bus transport in Teplice.Tramway transport was in Teplice over 60 years, this theses concerns with development with tram-lines, accidents and unrealized projects, which were financial and technical ambitious often.Technical and fiancial availability of tramway and trolley bus transport is compared in last part.

This Master's Thesis deals with unconventional systems od public transport - TVR. The first part describes the theoretical foundation for the installation and functioning the public transport counting the technical requirements. The second part deals with unconventional systems, so called Tramways on tyres, which is run by two models - system Translohr and TVR. The Master's Thesis is focused on the economical and technical evaluation of each types of the public transport, mainly of the TVR, which is operated only in two cities over the world.

Only a few studies have looked at microbial biogeography in soils and whether microorganisms are endemic to an area is still debatable. Tramway Ridge, a geothermal area on Mount Erebus, Antarctica, provides a unique opportunity due to its isolation and extreme conditions to explore the possibilities of microbial endemism and to identify novel Bacteria and Archaea. This site was chosen for a culture-independent study with a preliminary culturing survey for bacterial communities along three temperature gradients (65 C - 2.5'C). In addition, a physico-chemical analysis was undertaken to identify which environmental factors were driving the different diversity along the transects. An automated rRNA intergenic spacer analysis (ARISA) was used to assess the diversity across the transects using Bacteria and Cyanobacteria-specific primers and results showed that temperature and pH were the main drivers for these communities. Due to its unique physico-chemical and ARISA profile, a hot temperature site (T-3A, 65'C) was chosen for further investigation by bacterial and archaeal 16S rDNA clone libraries. Unique rDNA types among the 78 bacterial and 83 archaeal clones were identified by restriction fragment length polymophisms and 18 bacterial and 5 archaeal operational taxonomic units (gt97% identity) were observed. All of the bacterial sequences were deeply branching and loosely affiliated with other recognised bacterial divisions, with 40% of the sequences not affiliated to any genus. The archaeal clones were found to be deep-branching and sequences clustered together within the Crenarcaheota. In addition, two strains of Bacilli were isolated. The novel microorganisms show that the Tramway Ridge communities are unique from organisms found in other environments and show that quotEverything is (not) everywherequot.

Esse trabalho analisa a trajetória do Tramway da Cantareira em sua relação com o desenvolvimento das regiões atendidas por seus ramais, notadamente a zona norte do município de São Paulo e Guarulhos, tendo como recorte temporal os anos de 1893 a 1965, período de funcionamento dessa linha férrea. Para isso, além da bibliografia pertinente acerca do assunto, utiliza como fonte de pesquisa amplo conjunto documental de cunho arquivístico e, de forma complementar, periódicos que circulavam na época. Subdividida em quatro capítulos, esta tese analisa inicialmente a crise de gestão dos recursos hídricos na capital de São Paulo na segunda metade do século XIX com vistas a compreender as razões de o governo estadual ter iniciado a construção do Tramway da Cantareira. Em seguida, estuda os primeiros anos de funcionamento da ferrovia, momento no qual ela presta importante contribuição nas obras de infraestrutura da capital, com destaque para aquelas relacionadas ao abastecimento de água e saneamento básico. Uma vez analisada a história de seus anos iniciais, o trabalho busca compreender a percepção que a população, a imprensa e o governo tinham em relação aos seus serviços, examinando os projetos que previam desde o seu arrendamento à iniciativa privada até a sua extensão para além dos municípios de São Paulo e Guarulhos, em uma fase na qual o transporte de passageiros já se tornava a sua principal atividade. Por fim, examina o processo de anexação dessa linha férrea à Estrada de Ferro Sorocabana até o momento de sua desativação, em 1965. / This study analyzes the trajectory of the Cantareira Tramway in its relation with the development of the regions served by its branches, notably the northern part of the municipality of São Paulo and Guarulhos, focusing in the years from 1893 to 1965, period of operation of the railroad. To this end, besides the pertinent bibliography on the subject, this study uses as a research source a large set of archival documents complemented by periodicals circulating at the time. Subdivided into four chapters, this thesis initially analyzes the crisis of water resources management in the capital of São Paulo in the second half of the 19th century, in order to understand the reasons why the state government started the construction of the Cantareira Tramway. Subsequently, it studies the first years of the railway operation, when it makes an important contribution to the infrastructure works of the capital, especially those related to water supply and basic sanitation. Once the history of its initial years is analyzed, this study tries to understand the perception that the population, the press and the government had concerning the Cantareira Tramway services, examining the projects it predicted from its lease to the private sector until its extension beyond the municipalities of São Paulo and Guarulhos, in a period where transportation of passengers was already its main activity. Finally, it examines the annexation process of this railway to the Sorocabana Railroad until it was decommissioned in 1965.

Le redéploiement des réseaux de tramways en France a modifié considérablement les espaces publics et la façon dont ils sont pratiqués. Au-delà de l’image de développement urbain durable portée par le tramway, la question des difficultés d’usage de ces espaces est peu investiguée. Ce travail s’appuie principalement sur la mise en lien des analyses des pratiques des espaces publics réaménagés pour le tramway (observations in situ, interviews d’usager, analyses des accidents), avec celles des processus de conception de ces espaces (entretiens réalisés avec les différents acteurs des projets de tramway étudiés, révélant les enjeux, les choix, les conflits, les contraintes et les compromis ayant pesé dans l’aménagement de ces espaces). Les villes de Montpellier, Marseille et Nice sont les trois terrains d’étude sur lesquels ont porté ces investigations. Les résultats de cette thèse montrent d’une part que l’insertion de tramways modernes dans les villes françaises pose certains problèmes de complication des espaces publics. Ces complications, liées à la restructuration des espaces publics pour le tramway, engendrent des difficultés d’usage et des problèmes de sécurité. Ils montrent d’autre part que les processus de conception jouent un rôle dans la genèse de ces problèmes. Cette thèse établit ainsi des liens particuliers entre complexité des processus de conception (au sens de la pensée complexe) et complication des espaces publics. / The reintroduction of tram networks in France has considerably changed public spaces and the way citizens use them. Above and beyond the image of sustainable urban development conveyed by trams, the question of the difficulties encountered by the users of these spaces has not been studied much. This work is mainly based on the coordination of the analysis of the uses of these re-designed public spaces (through observations, interviews of users and accident studies) and the analysis of the conditions and processes involved in the design of these spaces (mainly based on interviews with the actors of these tram projects, to identify the choices made, compromises accepted, and conflicts and constraints at work that determine the layout of these spaces). The cities of Montpellier, Marseille and Nice are the three fields of study on which the demonstration of this thesis is based. On the one hand, the results of this research show that the insertion of tram tends to complicate the public spaces. These complications related to the restructuring of public spaces for the tram create difficulties of use and safety concerns. On the other hand, this research shows to what extent the complexity of the design processes plays a role in the genesis of these problems. This thesis thus establishes particular links between complex design processes (in the sense of “complex thought”) and complicated public spaces.

Le choix d'un système de transport guidé de surface exploité en site propre (TCSP) est un travail complexe et difficile. Les différents systèmes peuvent sembler offrir des services équivalents pour les utilisateurs tandis que manquent souvent les informations nécessaires pour mieux distinguer les différences entre tel ou tel système. L'objectif de cette recherche vise, au-delà d'une présentation des différents systèmes guidés de surface qui structurent les réseaux de transport public en France, à procéder à une analyse comparative afin de mieux guider les choix des collectivités territoriales, dans le contexte des efforts qu'elles conduisent pour promouvoir des transports urbains répondant aux enjeux du développement durable. Les avantages et points faibles de chaque système est analysé et présenté de manière désagrégée. De manière complémentaire, est proposée et discutée une méthode multicritère ELECTRE III permettant d'agréger les résultats obtenus et de proposer le (ou les) système(s) le(s) mieux adapté(s) à différents contextes d'exploitation. Le résultat principal met en évidence le fait que le tramway moderne sur fer occupe une place privilégiée dans la majorité des scenarii. Cependant, le CIVIS, le Translohr, TVR et même le trolleybus ont leur place selon le contexte d'exploitation, dès lors en particulier que sont pris en compte les coûts d'infrastructure et d'exploitation associés. Les résultats de cette recherche nous encouragent en outre à recommander, chaque fois qu'il y a un projet de système de transport de surface, de passer en revue la gamme des systèmes et d'effectuer l'analyse comparative avec les différentes contraintes du lieu et du moment, en y intégrant une vision de moyen et long terme et les effets prévisibles sur l'aménagement urbain / The choice of a guided surface transit system operated on separated RoW is a complex and difficult task. Even if different transit systems could provide equivalent services to users, we often lack the necessary information to better distinguish among different systems. Beyond giving a presentation of different surface guided systems structuring the public transport networks in France, the aim of this research is to conduct a comparative analysis in order to better guide decisions of local authorities in their efforts to promote urban transport that meets the challenges of sustainable development. The advantages and the drawbacks of each system are analyzed and presented in a disaggregated way. In addition, a multicriteria method ELECTRE III is proposed and discussed for aggregating the results and proposing system(s) best suited for different operating conditions. The main result shows that the modern tramway on rail occupies a privileged place in most scenarios. However, the CIVIS, Translohr, TVR and even trolleybuses have their places with respect to operating conditions, given that the related infrastructure and operating costs are taken into account. The results of this research therefore encourage us to recommend, every time we propose a surface transit system, to review the whole range of systems and to do the comparative analysis with different context and time constraints integrating mid-term and long-term visions and predictable effects on the urban requalification
