Transportation is an essential part of city life. However the extensive use of private cars in urban transport systems leads not only to a decrease in public health and quality of life but also drives global warming through the emission of GHG. The growth rate of CO 2 emissions caused by transportation is among the highest across all energy sectors. In order to mitigate climate change, it is therefore crucial to reverse this trend and change urban transport systems towards more climate compatibility. Thus, this thesis investigates if and how mobility demand and climate protection can be combined in urban transport systems.To answer these questions, the thesis discusses characteristics of climate-friendly transportation based on findings from academic literature. Moreover, policy instruments to transform urban transportation towards climate compatibility as well as possible obstacles and constraints in this regard are investigated. More precisely, socio-technical/infrastructural, technological, financial, legal, institutional/organisational, political, habitual, and cultural constraints are described and the significance of pragmatic, moral, and cognitive legitimacy is ascertained with regard to public and political acceptance of policies.Drawing on these theoretical assumptions, the case of Berlin is analysed in more detail. Based on policy documents, statistical data, expert interviews, and a public hearing in the Senate of Berlin, it is investigated how the city plans to make its transport system more climate-friendly and what the actual state of climate compatibility within the transport sector is at the moment. As a result, it could be observed that policies for climate-friendly transport are in place and mostly implemented but that the amount of CO 2 emissions caused by the transport system and especially by road traffic has more or less stagnated since the 1990s. Several reasons for this development could be ascertained: The transformation towards climate compatibility is, on the one hand, constrained bylegal, infrastructural, institutional, political, habitual, and cultural factors as well as by the lack of personnel within the city administration, and, on the other hand, hampered by the perceived inacceptability of car-restrictive policies.The conclusion from this thesis is therefore that it is thereotically possible to combine mobility demand and climate protection in urban transport systems and it is furthermore imperative in order to mitigate climate change and its dreaded impacts. In practical terms, however, cities face several intertwined and often very distinct obstacles and constraints that can only be overcome by long-term, dedicated, and citizen-oriented policy planning and implementation.

The dissertation deals with main problems of the justification of urban transport systems infrastructure development solving methodological issues of preparation, selection and implementation of projects. These issues are relevant for the implementation of sustainable urban development strategy of Lithuania as a member state of the European Union. The main aim of the Research is to develop a theoretical model for the justification of urban transport systems infrastructure development by adapting the model for the identification of priorities and practical execution of construction or reconstruction projects. The following tasks have been set for implementation of the objective of the Research: to analyse the objects of the current urban transport infrastructure and their role in sustainable urban development, to define the trends for their development; to analyse the principles for justification of transport infrastructure development projects; to carry out the analysis of the assessment methods applied during the processes of justification; to develop a theoretical project justification model by defining social – economic and other characteristic assessment criteria and aspects; to test theoretical performance of the developed model through the assessment of the selected and implemented urban transport infrastructure development projects in Lithuania. The dissertation consists of Introduction, 4 chapters, Conclusions, References and 6 Annexes. The Introduction reveals the...

Šio darbo pagrindinis tikslas – sukurti teorinį miestų susisiekimo sistemų infrastruktūros plėtros projektų pagrindimo modelį, pritaikant jį prioritetų nustatymui ir praktiniam susisiekimo sistemų infrastuktūros statybos ir rekonstravimo projektų vykdymui. Darbe sprendžiami keli pagrindiniai uždaviniai: išanalizuoti šiuolaikinių miestų susisiekimo sistemų infrastruktūros objektus, nustatyti susisiekimo sistemų infrastruktūros plėtros tendencijas, įvertinant egzistuojančias miestų susisiekimo problemas; atlikti naudojamų susisiekimo infrastruktūros plėtros projektų pagrindimo principų, naudojamų vertinimo metodų analizę; suformuoti plėtros projektų pagrindimo principus miestų susisiekimo sistemų infrastruktūrai; sudaryti teorinį projektų pagrindimo modelį, nustatant būdingus vertinimo kriterijus ir aspektus; patikrinti sudaryto modelio praktinį veiksmingumą, atliekant pasirinktų įgyvendintų ir įgyvendinamų Lietuvos miestų susisiekimo sistemų infrastruktūros plėtros projektų vertinimą. Disertaciją sudaro įvadas, keturi skyriai, rezultatų apibendrinimas, naudotos literatūros ir autoriaus publikacijų disertacijos tema sąrašai ir 6 priedai. Įvadiniame skyriuje aptariama tiriamoji problema... [toliau žr. visą tekstą]
