Personal Rapid Transit systems for reduction in car dependence Karlskrona case study

Lichtenberg, Rose, Guimarães, Patricia, Podsedkowska, Heleen January 2008 (has links)
This research project is designed to enhance the planning process that can aid authorities moving towards sustainable and economically feasible local and regional mobility systems. The improvements that have been made to transit so far have not been successful in breaking the trend of increasing car traffic and decreasing transit trip making. This means that sustainable mobility is a complex system which also encompasses changing attitudes and behaviours, integrating spatial and energy planning into it, and looking upstream to affect the causes of the problem instead of downstream to just fix its consequences. Environmental impacts (noise, pollution, health problems), accidents and congestion are all by-products of transport activities – they are the so-called external costs – and must be made part of the equation. European guidelines were analysed, as well as the results of many of the European Union‘s mobility research programs. The core of the research analyses how to move Karlskrona municipality‘s mobility system towards its vision of success in the future through the Framework for Strategic Sustainable Development – Sustainable Mobility (FSSD-SM). Backcasting from a sustainable vision in the long-term future is central to this process. The Municipality of Karlskrona, in Sweden, is the case study. A sustainability analysis of Personal Rapid Transit (PRT) systems was undertaken to determine the feasability of integrating this modal system into the mobility solution for Karlskrona municipality.

Environmentální výchova a dopravní chování žáků vybraných základních škol v Česku / Environmental Education and pupils' transport behaviour of selected Elementary School in Czechia

Šafránek, Michal January 2017 (has links)
This thesis deals with the environmental education and the modal choice of transport, especially pupils traveling to school. The main object of the thesis is to determine, whether has the environmental education positive impact to a transport behavior of pupils and to their exploitation environmentally friendly means of transport. First part of the thesis is based on czech and foreign literature, it represents importance of the environment for people and other animals and plant species and deals with impact of transport on environment. This part also analyzes the environmental education and its possibilities, position and legislative and curricular anchoring in these times, everything with emphasis on influence of transport on the environment. Empirical part of the thesis is connected with first theoretical part of the thesis. Through a survey at czech elementary schools this part analyzes view of schools on transport and environmental issues and main factors, which influence modal choice. Two Prague elementary schools situated in similar type of a housing development with different approach to teaching the environmental education are studied in detail. Results suggest, that incorporating the environmental education into teaching leads to changes in transport behavior only in connection with...

Mobilidade urbana sustentável e o caso de Curitiba / Sustainable urban mobility and the case of Curitiba

Hellem de Freitas Miranda 13 October 2010 (has links)
O atual modelo de planejamento dos transportes é constantemente confrontado com novos ideais associados à mobilidade sustentável. Assim, inúmeros pesquisadores debruçam-se em busca de indicadores e índices capazes de avaliar e monitorar o desempenho de políticas públicas relacionadas ao tema. Dessa forma foi desenvolvido o Índice de Mobilidade Urbana Sustentável (IMUS), uma ferramenta pautada nos preceitos da mobilidade sustentável com a proposta de tornar-se um apoio à gestão municipal. Por ser um método recente, sua aplicação ainda é limitada. Assim, o objetivo deste estudo concentra-se em realizar o cálculo do índice na cidade de Curitiba, muito conhecida por suas soluções urbanas que associam o planejamento dos transportes ao uso do solo. A aplicação do método na cidade fundamentou-se não apenas em obter o simples score relacionado ao desempenho das condições da mobilidade local, mas também possibilitaram avaliar o próprio método. O valor resultante alcançado foi correspondente a 0,747, confirmando Curitiba como uma cidade com características bastante positivas quanto às políticas urbanas voltadas à mobilidade. Por outro lado, foram identificadas algumas deficiências, especialmente quanto aos modos não motorizados de transporte. O cálculo do IMUS permitiu encontrar também indicadores que não foram capazes de identificar aspectos reconhecidamente favoráveis da cidade, demonstrando que possivelmente esses apresentem problemas de avaliação ou normalização de valores. A aplicação do método também se mostrou eficiente para promover uma avaliação intraurbana entre as diversas regiões da cidade. Nesse aspecto Curitiba demonstrou um saudável equilíbrio, sem apresentar grandes disparidades quanto suas políticas locais. Tal característica mostra-se bastante favorável para identificar Curitiba como um benchmarking da mobilidade sustentável. Finalmente o método foi testado como uma ferramenta de comparação entre cidades distintas, demonstrando também ser eficiente, desde que se mantenha uma estrutura de cálculo compatível entre as cidades que se deseja comparar. / The current transportation planning approach is constantly confronted with new values derived from the concept of sustainable mobility. As a consequence, several researchers have devoted time and effort in the search of indicators and indexes capable of evaluating and monitoring the performance of urban policies related to the theme. The Sustainable Urban Mobility Index (I_SUM) was one of them. It is a decision support tool developed to help municipal administrations in the planning and management of sustainable mobility. As it is a recent method, its application is still limited to just a few cases. The objective of this study is to conduct an application of the index in Curitiba, which is a well-known city due to the quality of its urban planning solutions that associate transport planning to land use. The application of the method in the city was motivated not only by the possibility of having a score showing the performance of the city regarding sustainable mobility, but also by the opportunity of evaluating the method itself. The overall resulting value was 0.747, what confirms that Curitiba has very positive characteristics and effective urban policies regarding sustainable mobility. Conversely, some deficiencies were identified, especially concerning non-motorized transport modes. The I_SUM calculation also allowed the identification of indicators that were not able to identify aspects that are good to the city. That may suggest problems in the assessment or normalization procedures of the index. The method application was also efficient for the evaluation of city subdivisions. Curitiba also performed well in that intra-urban evaluation, with a positive equilibrium of the values throughout the city. It may be an indication that the city policies are homogeneously applied in the entire urban area, what certainly contributes to characterize Curitiba as a benchmark of urban mobility. Finally, when used to compare distinct cities, the method was also efficient. In that case, the calculation was compatible with a structure adjusted to simultaneously represent the compared cities.

Att sadla om och styra mot hållbar mobilitet : Användares perspektiv på hållbarhetsinitiativet LinBike - Linköpings elcykelpool

Holmsten, Jonathan, Arnåsen, Joakim January 2020 (has links)
Linköpings kommun invigde hösten 2019 en elcykelpool kallad LinBike i syfte att bidra till stadens utveckling och nå klimatmålen. Denna studie syftar till att undersöka användarna av LinBike för att förstå varför den används och huruvida den kan bidra till fler hållbara resor. Genom kvalitativa gatuintervjuer med 24 användare har fem olika mobilitetstyper identifierats som sammanfattar användarnas förhållningssätt till systemet. Analys av resultatet visar att elcyklarna främst används tack vare tjänstens bekvämlighet och prisvärdhet. LinBike bidrar till att användarna i många fall kan genomföra sina vardagliga resor enklare än innan. Förbättringsåtgärder föreslås som anses nödvändiga för att tjänsten ska behålla användare och bidra till en mer hållbar mobilitet. Studiens slutsatser är bland annat att klimatsmarta mobilitetstjänster bör fokusera på att vara smidiga och lättillgängliga för att locka användare. LinBike som färdmedel ersätter idag främst andra hållbara transportmedel och därför kan det inte konstateras att tjänsten bidrar till en mer hållbar mobilitet. / Linköpings municipality has during the autumn of 2019 established an electric bike-sharing system called LinBike with the purpose to contribute to the city’s development and reach its climate goals. The scope of this thesis is to study the users of LinBike to understand why it is used and whether it contributes to a sustainable mobility or not. Through qualitative street interviews with 24 users, five types of mobility users have been identified which summarize the users attitude towards the system. Analysis of the results demonstrate that the E-bikes are used mainly because of the convenience and the price of the service. LinBike helps make everyday travel easier than before. Improvement measures are proposed which are considered necessary for the service to maintain users and contribute to a more sustainable mobility. Conclusions are that climate-smart mobility services should focus on being comfortable and accessible to attract users. LinBike users usually replace other sustainable modes of transportation and thus it cannot be concluded that the service contributes to a more sustainable mobility.

#sustainabletransport : A FAIR Cross-Platform Social Media Analysis Approach to Sociotechnical Sustainable Transport Research

Stiebe, Michael January 2021 (has links)
The paper reports findings from a FAIR principles-based research project dedicated to investigating how cross-field research between the DH and Sociotechnical Sustainable Transport Research could help to enhance the holistic understanding of sociotechnical low-carbon transport transitions.  Using the hashtag search queries #sustainabletransport and #sustainablemobility, 33,121 Tweets (2013-2021) and 8,089 Instagram images including captions (2017/2018-2021) were mined using Python scripts. Quantitative text and sentiment analyses were applied to the Tweets and image captions. Additionally, an automated image analysis using the Instagram dataset was conducted. Synthesized results formed the base for the cross-platform analysis comprising: 1) hot topics, 2) mentioned users, 3) sentiment, 4) co-hashtags. Data were visualized via Tableau, Excel, RAWGraphs, and Bubbl.us. Whereas electromobility, one of Holden et al.’s Grand Narratives for sustainable mobility, has been significantly present in the digital discourse on both platforms (especially Instagram), #sustainabletransport has been closely associated with active transport, especially bicycling, and #sustainablemobility with the electromobility theme. The study has demonstrated the investigative potentials of cross-field cross-platform social media analysis studies and ultimately DH to enhance the understanding of sociotechnical low-carbon transport transitions. Drawing on core results, the paper also suggests an adapted version of the Geelsean Multi-Level Perspective.

To improve the efficiency of nudging techniques applied in the transition to sustainable mobility : An applied urban study within the transport sector

Fakhri, Mehri, Zeinodin, Rozita January 2022 (has links)
Global warming is one of the gravest concerns that the world is now dealing with. This phenomenon is caused by a variety of factors. Carbon dioxide emitted from transportation networks is a significant contributor to global warming. Transportation systems comprise both the urban mobility sector (including public transportation and private vehicles) and the road transportation system. In line with this issue, governments across the globe have been implementing new technologies and strategies to mitigate carbon dioxide emissions. Meanwhile, changing passengers’ mobility behaviors through the application of nudging techniques has recently been identified as a feasible option by them. This research seeks to improve the efficiency of nudging approaches used in the mobility sector by assisting local authorities in designing appropriate behavioral interventions. To do so, ten city representatives including sustainability experts, and city managers were chosen, and semi-structured interviews were carried out to thoroughly understand their needs and expectations in terms of selecting the most effective nudges for encouraging citizens to use more sustainable modes of transport. The collected data were analyzed applyingtheThematicmethod. Finally, using the Value Proposition Design model, the design characteristics for the development of an ‘Intervention Design Tool’are determined. Our findings reveal that features such as simulating scenarios and interventions based on the behavior context and then providing users with situation-aware nudges are crucial for the creation of an 'intervention Design Tool’. Furthermore, this device must provide city representatives, as the main user of the tool, with a comprehensive view of the targeted city while alerting them to crucial situations and trends. As a consequence, the benefits that city representatives obtain from using this tool include reducing effort and saving time while increasing the reliability of their decisions.

Integration von Nachhaltigkeit in der Bundesverkehrswegeplanung: Status-quo-Analyse und Weiterentwicklungsmöglichkeiten

Hartl, Richard 09 March 2022 (has links)
Der Bundesverkehrswegeplan (BVWP) stellt das zentrale Instrument zur Gestaltung des Verkehrs und der Mobilität in Deutschland dar. Der aktuelle BVWP 2030 sieht sich in Wissenschaft und Politik ebenso wie vorherige Fassungen des Plans der Kritik ausgesetzt, nicht zu einer nachhaltigen Entwicklung des Verkehrs beizutragen oder diese gar zu verhindern. Bisher findet sich in der Literatur jedoch keine systematische Betrachtung des Verfahrens und insbesondere der in ihm integrierten Bewertung von Nachhaltigkeitsaspekten. Ziel dieser Arbeit ist es, diese Lücke zu schließen. Hierzu nutzt die Arbeit die Methodik der qualitativen Inhaltsanalyse auf Basis der Theorie zu nachhaltiger Verkehrsentwicklung und Nachhaltigkeitsbewertung. Das Ergebnis ist ein Überblick über den Weiterentwicklungsbedarf der Bundesverkehrswegeplanung aus Perspektive nachhaltiger Verkehrsentwicklung. Diese Ergebnisse werden bisheriger Kritik und bestehenden Weiterentwicklungsvorschlägen gegenübergestellt und daraus eigene Empfehlungen abgeleitet. Eine grundlegende Neuordnung der Bundesverkehrswegeplanung sollte demnach Planungsannahmen transparent reflektieren, über eine reine Infrastrukturbereitstellung hinausgehen, ein strategisches (Nachhaltigkeits-)Zielsystem entwickeln, die Betrachtung auf Gesamtplanebene in den Mittelpunkt rücken (z. B. Entwicklung von Alternativszenarien) und das Verfahren auf darunterliegenden Planungsebenen an diesen ausrichten.:1 Einleitung 2 Charakterisierung der Bundesverkehrswegeplanung 3 Nachhaltigkeit im Verkehr 4 Integration von Nachhaltigkeit in Verkehrsplanungen 5 Entwicklung der Methodik zur Analyse des BVWP 2030 6 Ergebnisse der Analyse des BVWP 2030 7 Diskussion und Weiterentwicklungsempfehlungen 8 Schlussfolgerungen und Ausblick

Möjligheter eller motstånd : Politikers och tjänstemäns arbete i medelstora kommuner för att öka hållbar mobilitet / Opportunities or resistance : Politicians and civil servants work to increase sustainable mobility in medium-sized municipalities

Germsjö, Linnea, Kanhaleela, Iyara January 2023 (has links)
Vägtrafik skapar flera negativa konsekvenser för miljön men även för människors hälsa. Kommuner ansvarar för lokal infrastruktur och är därför en betydande del i arbetet med hållbar stadsutveckling. Studien undersökte hur politiker och tjänstemän i Sveriges medelstora kommuner arbetar för att bilen ska bli mindre attraktiv och för att öka hållbar mobilitet. Undersökningen utgick från Sveriges miljömål samt den strategi som innefattar nya etappmål för hållbar stadsutveckling. Frågeställningen besvarades genom att använda semistrukturerade intervjuer med fyra politiker och fyra tjänstemän från medelstora kommuner i Sverige. Resultat som framkom var att kommunerna arbetar med hållbar mobilitet i olika utsträckning utifrån olika förutsättningar och behov, men att lönsamhet och invånarnas åsikter begränsar arbetet. De slutsatser som drogs var att effektiva strategier krävs för att uppnå hållbar mobilitet vilket inkluderar ökade möjligheter för hållbart resande samt motstånd för bilanvändning. Att ha ett fungerande samarbete mellan politiker och tjänstemän samt ha en sakkunnig person på plats ansågs även vara viktiga prioriteringar och åtgärder. Eftersom att kommunerna värderar ekonomisk lönsamhet och invånarnas åsikter högre än miljön krävs dessutom prioritering på att öka nationell styrning och att regeringen måste sätta hårdare krav på kommuner. / Road traffic creates several negative consequences for the environment but also for human health. Municipalities are responsible for local infrastructure and are therefore a significant part of the work with sustainable urban development. The study examined how politicians and civil servants in Sweden's medium-sized municipalities work to make the car less attractive and to increase sustainable mobility. The study was based on Sweden's environmental goals and the strategy that includes new milestones targets for sustainable urban development. The method consisted of semi-structured interviews with four politicians and four civil servants from medium-sized municipalities in Sweden. The results showed that municipalities work with sustainable mobility to different extents based on different conditions and needs, but that profit and residents opinion limit the work. The conclusions were that effective strategies are required to achieve sustainable mobility which includes increased opportunities for sustainable travel and resistance to car use. Having a functioning collaboration between politicians and civil servants and having an expert on site were also considered important priorities and measures. Since economic profit and residents' opinion is valued higher than the environment by the municipalities, it is necessary to prioritize the implementation of national governance and that the government must set demands on municipalities.

BREAKING BARRIERS: Unveiling Best Practices for Promoting Urban Cycling

Bruijs, Karlijn January 2023 (has links)
This study investigates the barriers faced by cities in their efforts to increase the number of urban cyclists and aims to identify best practices to fulfil cities' ambitions. The research explores the multi-dimensional nature of the obstacles and highlights the significance of understanding and addressing them effectively. By examining bike policies, sustainable mobility programs, existing literature, and conducting interviews with experts, this study provides insights into the common themes that prevent cities from achieving their goals. The findings contribute to the development of best practices that can support cities in their ambition to increase urban cycling.This study is a multi-case study, where the study compares the city Malmö and The Hague. The Hague is a leading example for bicycle use, while Malmö strives to become a bicycle-friendly city. The methodology employed in this research includes several components: a literature review to explore barriers and enablers of urban cycling, a theoretical analysis, a comprehensive review of bike policies and sustainable mobility documents in both cities and interviews to delve deeper into recurring themes identified in the document analysis. The discussion section integrates the literature review, theory, and results, highlighting the best practices for promoting urban cycling.In this study, the theory of path dependency is employed, which refers to a process where initial moves lead to further moves in the same direction, limiting future choices. It involves three phases: Preformation, Formation, and Lock-in. Additionally, the theoretical framework incorporates the three factors of path dependence identified by Low et al. (2005). These factors are relevant to the study because they relate to urban planning and active transport. The three factors are: technical, institutional, and discursive. Overall, understanding path dependency and its factors (technical, institutional, and discursive) enables more effective strategies in urban planning and active transportation to overcome barriers and promote sustainable cities.Through an analysis of previous research, theory, and results it becomes evident that the establishment of a support base and the implementation of a combination of hard and soft measures play a crucial role in fulfilling cities' bike ambitions. The support base requires diverse stakeholders to understand and support bike policies. Effective communication help engage stakeholders and expand support. Overplanning with various options enhances policy resilience. Striking a balance between hard and soft measures is crucial for increasing urban cyclists. Hard measures like infrastructure development are initially important, but a balanced approach ensures an effective strategy.By adopting these best practices, cities can successfully increase the number of urban cyclists. However, it is important to emphasize that achieving this ambition goes beyond formulating a policy; it requires the establishment of a support base and a balanced approach that incorporates both hard and soft measures. This study provides cities with insights into potential barriers and enablers, offering guidance for examining their specific urban contexts and working towards their cycling goals.

Samverkan för hållbar mobilitet : Realisering av en gemensam mobilitetsplan på områdesnivå: drivkrafter, hinder och lärdomar / Collaboration for sustainable mobility : Realizing a common mobility plan at an area level: drivers, barriers and lessons learned

Hagström, Mikaela, Ljunggren, Elin January 2023 (has links)
Vår värld som vi känner den håller på att förändras på grund av klimatförändringar som berorav mänskliga aktiviteter. För att minska effekterna av stigande halter växthusgaser måste alladelar av våra samhällen minska utsläppen, där byggandet av bostäder och transporter är storautsläppsområden som måste förändras i grunden. Det har lett till en växande insikt omeffekterna för urbana transporter, som har resulterat i ökad efterfrågan på lösningar som kanförbättra mobiliteten i städerna och dessutom sänka utsläppen av växthusgaser. En av delösningar som har fått ökad uppmärksamhet är mobilitetshubbar. Dessa hubbar beskrivs somsamlingsplatser för olika färdmedel och tjänster som främjar hållbart resande, som till exempelkollektivtrafik, delningsfordon och aktiv mobilitet. En identifierad problematik medmobilitetshubbar är den bristande erfarenheten i att ta beslut om vilka funktioner som ska ingå,hur de ska finansieras och hur kostnader och intäkter ska fördelas. Detta skapar ett behov avsamverkan mellan offentliga och privata aktörer. Denna studie syftar till att undersöka hur byggherrar och kommun kan samverka kringmobilitetslösningar på områdesnivå. Studien baseras på en fallstudie avstadsutvecklingsprojektet Sege Park i Malmö. Resultaten visar att staden ställt höga krav föratt Sege Park ska bli ett attraktivt bostadsområde där hållbara resor prioriteras och blir enklaatt nyttjas av de boende. Det har lett till att områdets parkeringsbehov och mobilitetstjänstersamlats i ett gemensamt parkeringshus. Samtidigt har byggherrarna behövt arbeta fram olikainnovativa gemensamma mobilitetsåtgärder för att få boende i området att välja bort att äga enegen bil. För första gången har en mobilitetsplan som omfattar flera fastigheter skrivits, vilkethar krävt högre grad av samverkan mellan byggherrar och staden. Studiens material har samlats in genom de olika metoderna: litteraturstudie, fallstudie,dokumentdata och intervjuer. Det teoretiska ramverket som används i studien utgår från enmodell om samverkansstyrning (collaborative governance), som har utvecklats av Emerson,Nabatchi och Balogh (2012). Studien identifierar ett flertal drivkrafter för att samordnautveckling och drift för delade mobilitetsåtgärder på områdesnivå. Däribland en ekonomiskvinning, en bättre helhet och större nytta för de boende. Det har också identifierats ett antalhinder, som olika förutsättningar och tidsperspektiv samt bristande ledarskap, vilket har lett tillonödigt tidskrävande processer. Studien visar på vikten av samverkan mellan byggherrar ochstaden, samt behovet av ledarskap och tydlig struktur för att underlätta samarbetet ochmöjliggöra en effektiv implementering av hållbara mobilitetslösningar på områdesnivå. / Our world, as we know it, is undergoing changes due to climate change caused by humanactivities. To mitigate the effects of rising greenhouse gas emissions, all sectors of our societymust reduce their emissions, with housing construction and transportation being significantareas that require fundamental transformation. This has led to a growing recognition of theimpacts on urban transportation, resulting in an increased demand for solutions that canimprove mobility in cities while reducing greenhouse gas emissions. One solution that hasgained attention is mobility hubs. These hubs are described as gathering places for variousmodes of transportation and services that promote sustainable travel, such as public transit,shared vehicles, and active mobility. A challenge with mobility hubs is the lack of experiencein making decisions about which functions to include, how to finance them, and how to allocatecosts and revenues. This creates a need for collaboration between public and private actors. This study aims to investigate how developers and municipalities can collaborate on an arealevel for mobility solutions. The study is based on a case study of the urban development project Sege Park in Malmö. The results show that the city has set high requirements for SegePark to become an attractive residential area where sustainable travel is prioritized and easilyaccessible to residents. This has led to the consolidation of the area's parking needs and mobilityservices in a shared parking facility. At the same time, developers have had to developvarious innovative shared mobility measures to encourage residents to choose not to own a private car. For the first time, a mobility plan encompassing multiple properties has been developed,requiring a higher level of collaboration between developers and the city. The study's data has been collected through various methods: literature review, case study,document analysis, and interviews. The theoretical framework used in the study is based on amodel of collaborative governance developed by Emerson, Nabatchi, and Balogh (2012). Thestudy identifies several drivers for coordinating the development and operation of sharedmobility measures, including economic benefits, a better overall outcome, and greater benefitsfor residents. Several barriers have also been identified, such as varying conditions and timeperspectives, as well as a lack of leadership, leading to time-consuming processes. The studyhighlights the importance of collaboration between developers and the city, as well as the needfor leadership and a clear structure to facilitate cooperation and enable the effectiveimplementation of sustainable area-level mobility solutions.
