Investigating end-user acceptance of autonomous electric buses to accelerate diffusion

Herrenkind, Bernd, Brendel, Alfred Benedikt, Nastjuk, Ilja, Greve, Maike, Kolbe, Lutz M. 08 September 2021 (has links)
To achieve the widespread diffusion of autonomous electric buses (AEBs) and thus harness their environmental potential, a broad acceptance of new technology-based mobility concepts must be fostered. Still, there remains little known about the factors determining their acceptance, especially in the combination of vehicles with alternative fuels and autonomous driving modes, as is the case with AEBs. In this study, we first conducted qualitative research to identify relevant factors influencing individual acceptance of autonomously driven electric buses. We then developed a comprehensive research model that was validated through a survey of 268 passengers of an AEB, operated in regular road traffic in Germany. The results indicate that a mix of individual factors, social impacts, and system characteristics determine an individual’s acceptance of AEBs. Notably, it is important that users perceive AEBs, not only as advantageous, but also trustworthy, enjoyable, and in a positive social light. Our research supplements the existing corpora by demonstrating the importance of individual acceptance and incorporating it to derive policy implications.

Mediální obraz pražské dopravy / Media Image of Transport in Prague

Morongová, Denisa January 2018 (has links)
This diploma thesis contributes to sustainable transport in Prague. It analyses media texts from six selected Czech printed newspapers (Blesk, Mladá fronta Dnes, Pražský deník, Metro, Hospodářské noviny, Právo) by using the theoretical and methodological strategy of critical discourse analysis by Norman Fairclough. These texts were found through media database Anopress IT by using keywords about sustainable transport in the capital city of Prague in years 2010 till 2018. This thesis is divided into four main parts. The theoretical part is dedicated to the terms of mobility management, the social construction of reality and discourse. The methodological part is focusing on discourse analysis, critical discourse analysis and the approach by Norman Fairclough. The analysis identified five topics in the discourse of sustainable transport in Prague - electromobility, public transport, foot traffic, urban cycling, and Sustainable Mobility Plan. Sustainable mobility in Prague is presented in a context of the polluted environment which should be solved by "ecologically, environment- friendly, clean". The most media texts were dedicated to public transport and electromobility. Just one text was about foot traffic as a sustainable type of mobility. Participants were mostly from Prague city hall, however, not...

Social participation for sustainable mobility : The effects of digital transformation on mobility behavior

Guerreiro Augusto, Marc January 2020 (has links)
Overall traffic in Germany is constantly increasing. Automobiles account for 57 percent of all trips in the country (BMVI, 2018). Steady population growth, urban agglomeration, and sprawl of cities contribute significantly to this trend. Simultaneously, the rise of digital services is progressively complementing travel by route planning, navigation, and ticketing. Therefore, a redesign and reinterpretation of the traditional understanding of the mobility landscape is required. The purpose of this work is twofold. First, to investigate the effects of digital transformation on people’s mobility behavior in public space, arguing for ecosystems in blended space being a consequence of the digital transformation at large. Second, to explore how social participation can lead to societal change for sustainable travel in the context of digital transformation. Digital technology has blurred the boundaries between physical and digital. Although physical and digital spaces are treated as separate parts, the former relates to the success of the latter. Qualitative interviewing was applied to systematically create an understanding about key actors’ roles and interdependencies as well as their perspective on how digital technologies modify today’s mobility landscape. This work concludes that the digital transformation allows individuals to influence travel demand purposefully. The system’s underlying structure reveals travel as purposive demand, a pattern extending the understanding of travel as a derived demand and valued activity. The Multi-Layered Participatory Process (MLPP), developed on the basis of the study’s findings, provides means to enable large scale social acceptance for sustainable mobility behavior.

Det trafkstrategiska arbetet för att främja hållbar mobilitet : En kvalitativ studie av två stora svenska kommuner / The traffic strategic work to promote sustainable mobility : A qualitative study of two large Swedish municipalities

Söderqvist, Filip, Alder, Eric January 2022 (has links)
The transport sector currently accounts for a third of climate-affecting emissions in Sweden, which must be reduced in order for the government's target for climate emissions to be reduced by 70 percent by 2030 and for zero emissions to be achieved by 2045. This is done by encouraging sustainable modes of transport. This paper aims to investigate which policy instruments Malmö and Gothenburg use to encourage sustainable mobility. This is done on the basis of five qualitative interviews with the municipalities and the Swedish Transport Administration, as well as document analyzes of the municipalities traffic strategies. The results show that the main instruments focus on providing more space for cycling, walking and public transport, as well as reducing opportunities for car use, which is mainly done by limiting parking opportunities for cars. However, there are differences in the municipalities ability to implement sustainable mobility, which depends on the municipalities transport history and urban design, but also the ability to change their citizens' travel behavior.

Approaching sustainable mobility utilizing graph neural networks

Gunnarsson, Robin, Åkermark, Alexander January 2021 (has links)
This report is done in collaboration with WirelessCar for the master of science thesis at Halmstad University. Many different parameters influence fuel consumption. The objective of the report is to evaluate if Graph neural networks are a practical model to perform fuel consumption prediction on areas. The model uses a partitioning of geographical locations of trip observations to capture their spatial information. The project also proposes a method to capture the non-stationary behavior of vehicles by defining a vehicle node as a separate entity. The model then captures their different features in a dense layer neural network and utilizes message passing to capture context about neighboring nodes. The model is compared to a baseline neural network with a similar network architecture as the graph neural network. The data is partitioned to define an area with Kmeans and static gridnet partition with and without terrain details. This partition is used to structure a homogeneous graph that is underperforming. The practical drawbacks of the initial homogeneous graph are inspected and addressed to develop a heterogeneous graph that can outperform the neural network baseline.

Pedaling towards a sustainable future: lessons Learned from Cargo Bike Pool Operators in Sweden

Brandon David, Kvist January 2023 (has links)
This study examines the impact and potential of cargo bikes as socio-economically and ecologically beneficial modes of transportation. It focuses on the perspectives of cargo bike pool members and the challenges faced by pool operators. Three interviews were conducted with cargo bike pool operators in Sweden to understand the challenges and considerations involved in establishing and operating a pooling service, as well as their opinions on its financial future. Additionally, a user survey targeting pool members from one of the interviewed operators was conducted in 2020. The survey investigated user barriers, motivations, opinions towards the pooling service, and its effect on user mobility habits before and after joining. Although the acceptance and utilization of these services depend on factors such as proximity, pricing, availability, quality, and convenience of the service. The findings show that pooling services increase member interest in owning and using cargo bikes as a replacement for cars. However, concerns regarding the marketability of cargo-bike pools alone are raised in this study, thus, to enhance the attractiveness of cargo-bike pools, this study suggests incorporating additional modes of transportation, offering supplementary value propositions, and ensuring a user-friendly experience. On the operator side, this study highlights the importance of stakeholder collaboration in maximizing the potential of cargo bike pools for sustainable transportation enabling resource sharing, and marketing efforts, and improving the overall service by leveraging financial, spatial, and logistical benefits. Finally, this study finds that the current state of cargo bike pools necessitates collaboration and subsidies from municipalities and stakeholders. Suggesting innovations in business models and increased marketing strategies that capture a broader demographic through an enhanced value proposition that includes other forms of modality and benefits in their services, are vital for the growth of cargo biking through pooling systems.  The research provides insights for prospective operators in establishing and operating cargo bike pools, emphasizing considerations related to the physical layout, financial aspects, marketing, and value proposition of the service and has broader implications in how to encourage more sustainable mobility practices.

The implementation of e-scooters in Linköping municipality : Opportunities and challenges for sustainable transportation

Jesper, Kuduk January 2022 (has links)
Across the world, efforts are being made to deal with climate change, where development in different fields is being made to transition towards a sustainable future. Transportation has become one component of this, resulting in the emergence of micro-mobility. One popular micro-mobility mode discussed by many scholars and introduced in many places, including the city of Linköping, is e-scooters. E-scooters have become popular due to the flexibility they offer. However, they have contributed negative aspects too. Therefore, I have investigated how the implementation of e- scooters has affected Linköping municipality in terms of the built environment, travel habits, and sustainable goals perspective. I further describe the approach to socio-technical transition by introducing a niche innovation and, in this case, e-scooters to improve the current transportation system to steer towards a low-carbon future. The impact e-scooters have had in Linköping municipality will be captured through interviews with the officials and politicians from the municipality. The findings showed that e-scooters negatively impacted the built environment by putting more pressure on an already crowded city. Some e-scooters would be carelessly parked, posing a danger to other traffic users. As a result, specific regulations, such as geo-zones, were made to reduce e-scooters being wrongly parked. In Linköping city, e-scooters have mostly replaced walking and public transport trips. Because e- scooters are still relatively new in Linköping municipality, their contribution to the municipality's sustainable goals is limited and difficult to assess.

Rena rama vilda västern : Den hållbara mobilitetsdiskursens påverkan på transportjämlikhet på landsbygden - upplevelser bland planerare och resenärer / It is like the wild west : The impact of the sustainable mobility discourse on transport equality in rural areas - experiences among urban planners and travellers

Adell Duveborn, Maja, Eriksson, Arvid January 2022 (has links)
Developing and building cities in a sustainable way is essential in modern day planning. A huge factor that influences this is the transport sector. The growing discourse of sustainable mobility is transport researchers answer to this but the lack of a social sustainability  perspective motivates research in relation to transport equality. The aim of this thesis is to increase the understanding of transport equality in Scania and contribute with insights primarily of how planning measures can be developed and consequences managed. To investigate the phenomenon, we look at how the sustainable mobility discourse affects transport equality with a focus on Scanias rural areas. We mainly examine cycling and public transport as two sustainable means of transport and how various priorities between and within these modes affect equality. Through interviews with both planners and travellers we establish an understanding of the phenomenon from two different perspectives. The study shows that general goals for increased share of travels by bicycle and public transport are governing traffic planning in Scania. Based on this, we argue that sustainable mobility is considerably more influential than the transport equality perspective. One strategy that clearly shows this is the dominance of the ridership goal in public transport planning. Geographical coverage has a lower priority compared to increasing the share of travels. The study concludes that there is a car dependency in rural Scania. The car is considered the obvious mode of transport due to flexibility, dangerous cycling conditions and the limited range of public transport. The poor public transport service can be seen as a direct result of the ridership goal. Resources from routes with less demand are reallocated to stronger routes and rural traffic is negatively affected as a result. There is also an understanding among travellers that service along rural routes are expensive and therefore not as justified by planners. However, this understanding among travellers is not accepted in the same way when it comes to the limited bicycle infrastructure. There is a strong wish for improved bicycle connections between small towns and cities, however the study reveals legal and organisational obstacles to the construction of bicycle infrastructure outside urban areas.
