We present the results of a stated preference study undertaken in Italy in 2017 on individuals’ preferences between an electric car (EC) and a petrol car, with the purpose of assessing the impact of ...the latent variable EC knowledge on purchasing decisions. We estimate a multinomial, a mixed and two hybrid mixed logit models, with the interaction between EC knowledge, car attributes and additional exogenous covariates. We use three measurement equations to estimate the self-assessed car knowledge, assessed EC knowledge and EC driving experience. We report three main findings. First, the inclusion of EC knowledge improves our capability to explain car choice. Second, the degree of EC knowledge does not change the negative perception respondents have, ceteris paribus, on ECs. Third, the level of EC knowledge influences the importance placed on the attributes of the choice model. Specifically, a higher level of EC knowledge is associated with a lower concern with fast charging station density. Our results are useful for car manufacturers who wish to improve their marketing strategies through tailored advertising efforts, and for policy makers who wish to implement educational campaigns as a means to foster EC uptake.
•People face self-driving cars with both fascination and reservation.•Openness towards self-driving cars correlates with both demographics and car use.•People are willing to ride in a self-driving ...car but are not yet ready to buy one.•Drivers do not trust self-drive technology to be safe and sophisticated enough.•Results suggest launching the technology gradually to increase both safety and trust.
In this paper we unpack and examine attitudes and potential barriers of end-users towards the self-driving car. We explore whether drivers have (mental) barriers and/or show resistance towards the self-driving car and, given such barriers and resistance are identified, investigate the main underlying reasons. Further, we suggest potential strategic implications for automotive companies and avenues to overcome, or at least mitigate, drivers’ barriers. The paper contributes to a better understanding of end-users’ opinions on radical innovations such as the self-driving car and strives to add value by linking scientific insights from both psychology as well as innovation literature. Only a limited number of studies so far have dealt with the potential barriers of users towards the self-driving car; therefore, it is our intent to provide first empirical evidence to trigger further research and foster a broader discussion on this relevant topic.
Cuba's Car Culture drives through Cuba's love of American cars of the '40s and '50s, and the ingenuity that keeps them running despite the U.S. embargo.
This is the first book to bring together the increasingly complex radar automotive technologies and tools being explored and utilized in the development of fully autonomous vehicles - technologies ...and tools now understood to be an essential need for the field to fully mature.The book presents state-of-the-art knowledge as shared by the best and brightest experts working in the automotive radar industry today -- leaders who have "been there and done that." Each chapter is written as a standalone "master class" with the authors, seeing the topic through their eyes and experiences. Where beneficial, the chapters reference one another but can otherwise be read in any order desired, making the book an excellent go-to reference for a particular topic or review you need to understand.You'll get a big-picture tour of the key radar needs for fully autonomous vehicles, and how achieving these needs is complicated by the automotive environment's dense scenes, number of possible targets of interest, and mix of very large and very small returns. You'll then be shown the challenges from - and mitigations to - radio frequency interference (RFI), an ever-increasing challenge as the number of vehicles with radars - and radars per vehicle grow.The book also dives into the impacts of weather on radar performance, providing you with insights gained from extensive real-world testing. You are then taken through the integration and systems considerations, especially regarding safety, computing needs, and testing. Each of these areas is influenced heavily by the needs of fully autonomous vehicles and are open areas of research and development.With this authoritative volume you will understand:How to engage with radar designers (from a system integrator / OEM standpoint); How to structure and set requirements for automotive radars; How to address system safety needs for radars in fully autonomous vehicles; How to assess weather impact on the radar and its ability to support autonomy; How to include weather effects into specifications for radars.This is an essential reference for engineers currently in the autonomous vehicle arena and/or working in automotive radar development, as well as engineers and leaders in adjacent radar fields needing to stay abreast of the rapid developments in this exciting and dynamic field of research and development.
Recently, policy makers' expectations about the role of electric cars in reducing emissions have risen substantially. In parallel, academic research on purchase intentions has dramatically increased. ...Originally, most studies have focused on utility attributes and price. More recently, several hybrid choice models have been estimated to include the impact of attitudes on choice probabilities. In addition, a few studies have caught the attention to social influence. In contributing to this line of research, this paper reports the results of an expanded hybrid choice, which simultaneously estimated all these different effects in a single integrated model of purchase intention. Results indicate that the model performs well. Costs considerations contribute most to the utility of electric cars. Social influence is less important, but there is also evidence that people tend to take it into consideration when there are positive public opinions about electric cars and the market share becomes almost half of friends of their social network. The intention to purchase an electric car is also influenced by attitudes about environmental concerns and technology acceptance.
In Keeping autonomous driving alive, Göde Both studies the relationships between researchers and artefacts held together by contested visions. Drawing on ethnographic fieldwork in a pioneering ...research project in Germany, he argues we can make sense of technological visions only if we simultaneously grasp the role of care, gender, and narrative in sustaining technological research.
The subject of this open-access publication is the impact of connected and automated vehicles on the European city and the conditions under which this technology can make a positive contribution to ...urban development. The authors put forward two theses that have received little attention in the scientific discourse so far: Connected and automated vehicles will not become fully established in all sub-areas of the city for a long time. As a result, previously assumed effects - from traffic safety to traffic performance as well as spatial effects - will have to be reevaluated. To ensure a positive contribution of this technology to the mobility of the future, transport and settlement policy regulations must be further developed. Established territorial, institutional and organizational boundaries need to be challenged in a timely manner. Despite or because of the existing great uncertainties, we are at the beginning of a phase of yet shaping the possible future - in technology development, but also in politics, urban planning, administration and civil society. Description of the chapters: 1. Connected and automated driving: The long level 4 Mathias Mitteregger reflects on the road ahead for automated driving. What pathways of technological development induce which kind of spatial effects and planning needs? 2. Connected and automated driving: Consideration of the local, spatial context and spatial differentiation Emilia M. Bruck and Aggelos Soteropoulos reflect on the importance of the local context when classifying and estimating the effects of different forms of automated mobility. 3. Connected and automated driving in the context of a sustainable transport and mobility transformation Andrea Stickler, Jens S. Dangschat and Ian Banerjee integrate possible potentials of automated mobility in the context of a transformed, sustainable transport system. PART I: Mobility and transport 4. Self-driving turnaround or automotive continuity? Reflections on technology, innovation and social change Katharina Manderscheid reflects on how differing visions of an automated future can be understood with regard to divergent interests in technological development. 5. Automated drivability and streetscape compatibility in the urban-rural continuum using the example of Greater Vienna Aggelos Soteropoulos analyses how different street spaces align with technological requirements of automated mobility, creating a suitability framework for road spaces in the Greater Vienna region. 6. Automation, public transport and Mobility as a Service: Experience from tests with automated shuttle buses The authors show what types of automated public transport might be used in the future and what can be learned from testing automated shuttle buses in the past. 7. Delivery robots as a solution for the last mile in the city? Bert Leerkamp, Aggelos Soteropoulos and Martin Berger describe how automated delivery robots could be contextualized in terms of solving last-mile problems and discuss what implications might lie ahead for urban planning. PART II: Public space 8. Control and design of spatial mobility interfaces The authors identify the possible implications of automated mobility for mobility interfaces and explore how public spaces could be transformed. 9. Transformations of European public spaces with AVs Robert Martin, Emilia M. Bruck and Aggelos Soteropoulos use the example of Copenhagen to show how public spaces could be transformed in an age of automated urban mobility and benefit from lower car dependency. 10. At the end of the road: Total safety Mathias Mitteregger discusses how the desire for road safety affects public spaces and how automated mobility influences this discourse. 11. Integration of cycling into future urban transport structures with connected and automated vehicles Looking at the future of mobility, Lutz Eichholz and Detlef Kurth show that the bike actually offers solutions to many of our current problems and that planning should not forget to integrate cycling into future urban transport structures and systems. 12. Against the driverless city Steven Fleming argues for a radical shift in cities towards a highly improved cycling infrastructure eradicating the need for automated mobility. Part III: Spatial development 13. Strategic spatial planning, “smart shrinking” and the deployment of CAVs in rural Japan Ian Banerjee and Tomoyuki Furutani show where automated mobility could help tackle pressing issues in rural Japan. 14. Integrated strategic planning approaches to automated transport in the context of the mobility transformation The authors show how new forms of automated mobility could be integrated into mobility systems in diverse spatial structures in the city region of Vienna with the overriding goal of the mobility transformation. 15. Opportunities from past mistakes: Land potential en route to an automated mobility system Looking at the mistakes made in building a car-centric environment in the past, Mathias Mitteregger and Aggelos Soteropoulos identify future areas of urban transformation as a result of a lower demand for car-centric infrastructures and businesses. Part IV: Governance 16. New governance concepts for digitalization: Challenges and potentials Alexander Hamedinger contextualizes the manifold paths towards an automated future with regard to governance and describes how governance concepts might need to adapt in the future. 17. How are automated vehicles driving spatial development in Switzerland? Fabienne Perret and Christof Abegg show how automated vehicles are influencing spatial development in Switzerland, focusing on three different scenarios on the road ahead. 18. Lessons from local transport transition projects for connected and automated transport Andrea Stickler looks at local projects aiming at a transformation of mobility practices and reflects on implications for automated transport. 19. Connected and automated transport in the socio-technical transition Jens S. Dangschat looks at societal transformations in the past and contextualizes automated mobility in terms of a possible socio-technical transition ahead. 20. Data-driven urbanism, digital platforms and the planning of MaaS in times of deep uncertainty: What does it mean for CAVs? Ian Banerjee, Peraphan Jittrapirom and Jens S. Dangschat show how continuous digitalization in cities might affect possible uses and implementations of CAVs and their accompanying systems.
This paper presents an evaluation of two commonly accepted Raman linewidth models typically used to fit CARS model parameters to data; the Modified Exponential Gap (MEG) and the Energy Corrected ...Sudden (ECS) models. The adjustable parameters in each model have been fit to published experimental linewidths, and comparisons are made to the various publications that have already provided similar adjustable constants. The approaches presented in the literature are discussed as are differences with the findings presented here.
