TL;DR: In this paper, the authors explore the potential of carsharing in replacing private car trips and reducing car ownership and how this is affected by its attributes and find that people vary significantly with respect to these two stated intentions, and that a higher intention of trip replacement does not necessarily correspond to higher intention to reduce car ownership.
Abstract: This paper aims to explore the potential of carsharing in replacing private car trips and reducing car ownership and how this is affected by its attributes. To that affect, a stated choice experiment is conducted and the data are analyzed by latent class models in order to incorporate preference heterogeneity. The results show that around 40% of car drivers indicated that they are willing to replace some of their private car trips by carsharing, and 20% indicated that they may forego a planned purchase or shed a current car if carsharing becomes available near to them. The results further suggest that people vary significantly with respect to these two stated intentions, and that a higher intention of trip replacement does not necessarily correspond to higher intention of reducing car ownership. Our results also imply that changing the system attributes does not have a substantial impact on people’s intention, which suggests that the decision to use carsharing are mainly determined by other factors. Furthermore, deploying electric vehicles in carsharing fleet is preferred to fossil-fuel cars by some segments of the population, while it has no negative impact for other segments.

TL;DR: In this paper, the authors examined the effect of performance expectation, effort expectation, Facilitating Conditions, social influence, price value and perceived safety on acceptance and usage of a newly introduced bicycle sharing system in Mashhad (MBSS), Iran.
Abstract: This study explores which factors influence bicycle sharing systems acceptance as a new transportation technology by identifying and describing their relationships to intention and usage behaviour. Using the latest version of technology acceptance models (UTAUT2), this study examines the effect of Performance Expectancy, Effort Expectancy, Facilitating Conditions, Social Influence, Price Value and Perceived Safety on acceptance and usage of a newly introduced bicycle sharing system in Mashhad (MBSS), Iran. The mediating effect of intention to use MBSS on the relationship between these constructs and use behaviour was examined. A total of 600 questionnaires were distributed at 128 MBSS stations of which 271 users responded. The result of a regression analysis indicated that intention to use MBSS was predicted by all the studied constructs except for Price Value, while a path analysis showed that through the Behavioural Intention, Facilitating Conditions was the only significant construct to influence Use Behaviour. Findings did not support age, income, education, and experience as moderating the relationships between the constructs and Behavioural Intention. This study recommends tracking the barriers of acceptance of bicycle sharing system by those population groups who do not use the system or use it less than the others. Moreover, findings of this study suggest improvements to Facilitating Conditions such as integration of public transport and MBSS, relocation of the stations to improve their (equity of) accessibility and, introducing motivational promotion campaigns, improving cycling social status, and improved customer service of staff may make MBSS more interesting for citizens.

TL;DR: In this paper, the authors define residential self-selection as the tendency of people to choose residential locations based on their travel abilities, needs and preferences, and present a related research agenda.
Abstract: This chapter gives an overview of the current debates on residential self-selection and presents a related research agenda. Here, we define residential self-selection as “the tendency of people to choose residential locations based on their travel abilities, needs and preferences.” Debates relate to theory/causalities (including the role of attitudes), research methods, empirical findings (including the magnitude of the importance of residential self-selection for the influence of the built environment on travel behavior and the dominance of OECD (Organization for Economic Co-operation and Development) countries), and the implications for planning. The main contribution is in translating the current debates into a research agenda. Challenging avenues for future research are partly inspired by these debates, and include changing attitudes, qualitative research, multiple causal structures, extending the scope to other areas than residential areas, the existence of threshold values for the strength of preferences to be important for residential self-selection, the role of perceived accessibility, non-OECD countries, and planning implications.

TL;DR: This article reviewed and discussed the literature on how equity is operationalized for the purpose of evaluating the impacts of transport policies and concluded that the equity of accessibility is the most evaluated topic studied.
Abstract: This chapter reviews and discusses the literature on how equity is operationalized for the purpose of evaluating the impacts of transport policies. It concludes that the equity of accessibility is the most evaluated topic studied. The Gini index is by far the most frequently used index for distributions of accessibility and other effects, probably because of ease of interpretability and communication. The literature on ethical preferences of people, at least as far as related to the distribution of effects of candidate transport policy options, is in its infancy. Interesting topics for future research include distributions in the area of safety, the environment, mobility, changes in distributions over time, preferences of potential users with respect to equity analyses, and the integration of equity analyses in wider evaluation frameworks.

TL;DR: It is shown that the accessibility component influenced by automated vehicles, the vehicle automation level, and the mobility service model (i.e., private or shared vehicles) would likely determine the magnitude and direction of social inclusion implications for these social groups.
Abstract: We analyze the implications of vehicle automation for the accessibility of vulnerable social groups (i.e., people on low income, people with physical and sensory disabilities, older people) and consequently for their transport-related social exclusion. First, we show that the accessibility component influenced by automated vehicles, the vehicle automation level, and the mobility service model (i.e., private or shared vehicles) would likely determine the magnitude and direction of social inclusion implications for these social groups. Positive implications for accessibility and thus social inclusion are expected to increase with the level of vehicle automation and vehicle sharing. Yet, the requirements for digital access and online payment for those services, vehicle custom-design, operating complexities, and uncertainties, insecurity and distrust in adoption new vehicle technologies could compromise possible accessibility gains and thus negatively influence social inclusion levels.

TL;DR: In this article, the authors present the first attempt to look for evidence of a non-linear relationship between mobility (measured as trip-making) and life satisfaction, and the first to test the direction of causality between the two factors.
Abstract: Travel is one of the most important facilitators of life and has been widely acknowledged as a prerequisite for economic and social activity. Research developing in recent decades has found that limitations to mobility and accessibility can reduce satisfaction with life. To date, research in this field assumes a linear and one-way relationship between the two—i.e. that ‘more mobility’ results in ‘more life satisfaction’. Yet diminishing marginal returns on happiness are found in many related fields such as economics, and there is always the possibility that happier people travel more than unhappy people. To the authors’ knowledge, this paper presents the first attempt to look for evidence of a non-linear relationship between mobility (measured as trip-making) and life satisfaction, and the first to test the direction of causality between the two factors. It uses a sample of some 1500 adults in the Netherlands Mobility Panel. Linear and segmented regression models were used to associate trip-making with satisfaction with life, when controlling for income, age, self-rated health and other demographics. Counter to expectations, five different model specifications suggest that the relationship between trip-making and satisfaction with life is linear. Furthermore, a structural equation model found that the relationship between mobility and satisfaction could run in either direction. This study questions many of the assumptions made about the relationship between transport and subjective well-being. Given the increasing prominence of this topic, much research is needed to further explore these complex relationships.

TL;DR: In this article, Narayanan et al. systematically summarized the most important findings and policy implications of each of the chapters and concluded that research that is conceptually rich is more valuable for policy making.
Abstract: This chapter first systematically summarizes the most important findings and policy implications of each of the chapters “Factors affecting traffic flow efficiency implications of connected and autonomous vehicles: A review and policy recommendations” by Narayanan et al.; “Automated bus systems in Europe: A systematic review of passenger experience and road user interaction” by Heikoop et al.; “Cyber security and its impact on CAV safety: Overview, policy needs and challenges” by Katrakazas et al.; “Cybersecurity certification and auditing of automotive industry” by Mateo Sanguino et al.; “The wider use of autonomous vehicles in non-commuting journeys” by Kimber et al.; “Policy implications of the potential carbon dioxide (CO2) emission and energy impacts of highly automated vehicles” by Annema; “Potential health and well-being implications of autonomous vehicles” by Singleton et al.; “Data protection in a GDPR era: An international comparison of implications for autonomous vehicles” by Costantini et al.; “Ethical issues concerning automated vehicles and their implications for transport” by Dogan et al.; “Governance cultures and sociotechnical imaginaries of self-driving vehicle technology: Comparative analysis of Finland, UK and Germany” by Mladenovic et al.; “Wider implications of autonomous vessels for the maritime industry: Mapping the unprecedented challenges” by Ghaderi; “The potential for automation to transform urban deliveries: Drivers, barriers and policy priorities” by Paddeu and Parkhurst. Next it synthesizes the overall findings and policy implications, and discusses future avenues for policy making and research. A first conclusion is that the chapters make clear that the ranges in policy relevant implications of AVs, within the scope of each chapter/topic, are still relatively broad. Secondly we conclude that research that is conceptually rich is more valuable for policy making. Thirdly we hypothesize that context matters for the uptake, impacts, and specific system design characteristics of real world AV implementation. Fourth we conclude that research on the global south has been limited so far. Fifth we argue that AVs, shared vehicles and electric vehicles (EVs) might stimulate each other in a positive way, in all directions. Finally we conclude that AVs will have wider societal implications, such as in the area of land use, accessibility, social exclusion, governmental expenditures, the labor market, and the environment. The more indirect the effects of AVs are, the more difficult they are to understand. For policy making a first conclusion is that the issues of ethics, cyber security and data protection deserve way more attention than they currently get. We also conclude that future motorway network extensions might not be no-regret anymore, because of possible congestion reductions due to AVs, but also because of decreasing marginal values of time. Finally we argue that countries that introduce AVs later than other countries can learn a lot from the real world experiences elsewhere.
