This thesis examines the issue of sharing of transport, namely the form car-sharing. Work defines the basic concepts of car-sharing, it advocates the concept of economic relations in line with the sustainable development of transport and describes the situation of car-sharing in the Czech Republic. The work also in the application part use the survey and looks to the usability of the cooperative model of car-sharing among students and younger workers in the Czech environment, and then compares this model with other modes of transport, from an economic perspective.

Diplomová práce popisuje a analyzuje negativní vlivy automobilové dopravy na životní prostředí a hodnotí jejich ekonomické dopady. Zároveň nabízí možná řešení těchto negativních vlivů. Jedná se především o řešení ekonomická, ale okrajově také o možnost řešení pomocí vývoje nových technologií. Jednou z možností snížení dopadů automobilové dopravy na životní prostředí je omezení používání vozidel. Mezi nástroje ke snížení jejich počtu patří hlavně zavedení placených parkovacích zón a výstavba parkovišť typu P+R a K+R. Dalším řešením je systém car-sharingu. Tento systém je rozebírán z pohledu efektivnosti, variabilních a fixních nákladů a předpokladů pro fungování. Práce analyzuje vliv daně na pohonné hmoty, substituce MHD a cyklistikou, cla a mýtného.

Theme of the diploma thesis is design of an urban electric car. The main aim of my diploma thesis is to create a concept of a vehicle which will benefit from advantages of utility vehicles and small urban cars . In my thesis I think about using of ecological materials, effective production technologies and requirements for car in present.

The aim of this report is to provide an analysis of potential benefits of a fleet of Shared Autonomous Vehicles (SAV) providing a taxi service to replace private car commuter trips in a metropolitan area. We develop a framework for dynamic allocation of SAVs to passenger trips, empty-vehicle routing and multi-criteria evaluation with regard to passenger waiting time, trip time and fleet size. Using a representation of current private trip demand for the Stockholm metropolitan area and a detailed road network representation, different scenarios (varying levels of accepted passenger waiting time at origin and accepted increase in travel time) are compared with respect to passenger travel time, number of vehicles needed and vehicle mileage. In a second step the environmental impacts of the different scenarios are assessed and compared using a life cycle approach. The assessment includes both a fleet consisting of currently in use gasoline and diesel cars as well as electrical cars. The results show that an SAV-based personal transport system has the potential to provide an on-demand door-to-door transport with a high level of service, using less than 10 % of today's private cars and parking places. In order to provide an environmental benefit and lower congestion an SAV-based personal transport system requires users to accept ride-sharing, allowing a maximum 30% increase of their travel time (15% on average) and a start time window of 10 minutes. In a scenario where users are not inclined to accept any reduced level of service, i.e. no ride-sharing and no delay, empty vehicle drive of an SAV-based personal transport system will lead to increased road traffic increasing environmental impacts and congestion. Envisioning a future using electrical cars a SAV-based system and electrical vehicle technology seems to be a “perfect” match that could definitely contribute to a sustainable transport system in Stockholm.

A well-crafted, locally adapted customer value proposition (CVP) can aid businesses in attaining loyal customers. The main purpose of this research is to determine the key value components that should be considered for the development of a CVP, for free-floating car sharing services in the Nordic region. This is done by establishing the relationship between deductively identified value components, perceived value, satisfaction, trust, and loyalty.  A research framework is proposed, where the relationships between the different constructs are hypothesised. Quantitative data is collected from existing car sharing users in the Nordic countries, through a self-administered online questionnaire, distributed through a non-probability sampling method. The empirical data is analysed through multiple regression analysis using the software SPSS, and the extension “PROCESS”, as well as additional analysis techniques to ensure data quality. The research findings indicate that perceived convenience, need fit, and a low service price positively impact both perceived value, as well as satisfaction. Satisfaction shows a stronger, positive effect on loyalty than that of perceived value, yet, loyalty is better explained when both constructs are accounted for. Additionally, trust shows to carry a mediating effect between both satisfaction and loyalty, as well as between perceived value and loyalty. Therefore, firms operating within this context should emphasise the customer needs to provide a service which is perceived as affordable and convenient. Finally, efforts should be taken to reduce uncertainty, and promote trust between the service providers, and their users.

Nowadays, circular economy is becoming more relevant in society. In the context of the automotive industry, we no longer simply work on emissions emitted during the vehicle use phase but rather on the environmental impacts induced during all phases of the vehicle's life cycle (manufacturing, logistics, use, maintenance and end of life). For this purpose, many automakers, including the Group PSA, use life cycle assessment (LCA) to determine these environmental impacts. Also, the economy of sharing is gradually established and follows innovative uses of the car. New mobility systems emerge and compete with the classical system of sales of vehicles. These new uses of the automobile mainly take the form of car-sharing. In the future, it will become essential to evaluate these services from an environmental point of view.Some studies of the use of car-sharing already demonstrate important consequences such as reductions in the number of vehicles and in the number of kilometers traveled but also an increase in the use of other means of transport. However, to my knowledge, there is no LCA-based method to quantify the environmental benefit of the use of a car-sharing service in relation to the use of vehicles for exclusive use by the owner but also which would eco-design these services and the vehicles intended for these services.As part of this six-month project, a LCA approach was implemented to a PSA B2C (business-to-consumers) car-sharing service called “Emov” with a fleet of 500 Citroën C-Zero electric vehicles. The goal was to compare the use of Emov in Madrid, Spain with the urban use of a private Internal Combustion Engine (ICE) vehicle and a battery electric vehicle for one user characterized by its frequency, its average time and its average distance of use over a defined period. Thanks to a modeling of the service on the LCA software Gabi and by controlling over the input parameters related to the Emov service and the parameters related to the user's use of the service (variable parameters), it was therefore possible to show the influence of these parameters on the final results. Furthermore, it was possible to show also in which scenario it was more environmentally beneficial to use the service rather than a private vehicle. For the study, six impact indicators were chosen: the potentials for global warming, photochemical oxidation, air acidification, water eutrophication, resource depletion and primary energy demand.Using Emov’s big data to inform the service parameters and then varying the service user's usage parameters, it was possible to conclude that whatever the user's urban mobility needs, it is more beneficial to use the service than a private ICE vehicle for five of the six impact indicators. Only the acidification potential indicator (SO2 equivalent) is worse when using the service, which can be explained by the manufacture of the batteries of the Emov vehicles.
