Overall synthesis and conclusions
No full textThis chapter first systematically summarizes the most important findings and policy implications of each of the chapters included in this book volume. 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.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Logistic
Spatial effects in the ex-ante evaluation of urban underground transportation infrastructure projects: A study of the gap between the perceived spatial effects of Het Souterrain and the spatial effects incorporated in already conducted CBAs
No full textUnderground transportation infrastructure projects are a possible solution to the increasing demand for transportation, limited space and congestion in urban areas. In addition, these kinds of projects are in line with the need for improvement of the quality of the public urban space. Nowadays, when a municipality applies for funding with the national government for the construction of a transportation project a Cost-Benefit analysis (CBA) has to be conducted by an independent party (Ministry of Infrastructure and the Environment, 2012). In the CBA the costs and benefits of the project on the society are balanced and therefore provides the CBA decision-makers with important policy information; whether the benefits outweigh the costs of the project compared to the state of affairs in which no project is build- also called the reference case (van Wee & Rietveld, 2014). The use of the CBA in the decision-making process leads to a better decision-making process (Mouter, Annema, & van Wee, 2013), but it is unclear which exact role a CBA plays in the decision-making process, because politicians also have other reasons than the results of a CBA for reaching a go/no-go decision (Rienstra, 2008; Eijgenraam, Koopmans, Tang, & Verster, 2000; Annema, 2014; Mackie, 2010). A limitation of the CBA is that not all (welfare) effects can be taken (properly) into account in a CBA (Mouter, Annema, & van Wee, 2015). CBAs are often incomplete because project effects are uncertain, unknown or difficult to monetize (Mouter, Annema, & van Wee, 2013). Under these conditions, political decisions based on results of a CBA study are based on incomplete policy information.Technology, Policy and ManagementDepartment of Transport and Logistic
Implications of automated vehicles for accessibility and location choices: Evidence from an expert-based experiment
No full textIn this paper, possible accessibility impacts of fully automated vehicles (AVs) are explored. A conceptual framework for those impacts is developed based on the model of four accessibility components (i.e. land use, transport, temporal and individual) of Geurs and van Wee (2004). Q-method is applied among a sample of seventeen international accessibility experts to explore heterogeneity among experts with respect to the impacts of AVs on accessibility, and study different views and clusters of experts. Q-method statements are deductively categorized according to four accessibility components of the conceptual framework. Three viewpoints were extracted, indicating that experts expect AVs to influence accessibility through all four accessibility components. Viewpoint A expects that accessibility benefits stemming from AVs will be highly uncertain, mainly because of induced travel demand that will likely cancel out travel time and cost savings of AVs in the long term. Viewpoint B anticipates that accessibility changes because of AVs will have two opposing implications for urban form: densification of city center and further urban sprawl. Finally, viewpoint C expects that those who can afford an AV will mainly enjoy AVs benefits, thus AVs will have more negative than positive implications for social equity.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and PlanningTransport and Logistic
Accessibility and equity: A conceptual framework and research agenda
No full textThis discussion paper proposes a conceptual model for the factors influencing ethical concerns regarding accessibility, building on the idea that people should have a minimum level of access to some destinations (founded in the ethical principle of sufficientarianism), and secondly from the idea that differences in levels of accessibility between (groups of) people could be relevant from an equity perspective (founded in the ethical principle of egalitarianism). The four components of accessibility introduced by Geurs and van Wee (2004) – the land use system, the transport system, the individual, and the temporal component – are included in the conceptual model which additionally disentangles the individual component, includes context factors (such as culture/religion), digital access options, perceived accessibility and normative judgments. In addition, this paper proposes a research agenda suggesting several types of quantitative and qualitative methods to study the complex relationships proposed in the model, and research to address those parts of the model for which limited knowledge is currently available.Transport and Logistic

The Return of Billiard Balls? US–China Tech War and China’s State-Directed Digital Capitalism
No full textMedia policy analysts of (neo)liberal persuasion have long seen China as an anomaly. This is, however, a narrow perspective, whose explanatory power pales facing the challenge of recent events. Drawing upon International Relations (IR) theories, this article reflects on the contradicting ideas of (neo)liberalism and (neo)realism in digital media policy, while examining US–China tech war and China’s state-directed platform capitalism. It argues that more attention should be paid to neorealist frameworks, especially Mearsheimer’s offensive realism, which sees the world as consisting of billiard balls bumping into each other, pursuing hegemony. How is offensive realism useful in helping understand recent events about China? How is it also limited? Are we returning to an era of billiard balls? What are the implications for digital media policy to transcend platform capitalism and approach platform socialism?.Nanyang Technological UniversityThis article was produced within the framework of the Jean Monnet Network on the European Media and Platforms Policy (EuromediApp), supported by the Erasmus+ Program of the European Union (2021-23).

Robust Transport and Assembly Automation System Using Vision-Based Control Using UAV
No full textWe propose an automated system that moves blocks to a specific location, such as a block map, using Unmanned Aerial Vehicle (UAV). The system was developed in a simulation environment using Gazebo simulator, and the test environment was set with different GPS noise and illuminance in order to resemble the real environment. To increase the accuracy of the system, we used an algorithm that picks up and places blocks using vision-based controls using deep learning-based object detection and recognition, not just GPS based control. In addition, when picking up and placing blocks, it is easy to execute by using a magnet module rather than a typical manipulator. Our proposed system in simulation experiments in various environments consistently showed excellent performance. The system seems to have robust performance in a more difficult environment than existing robots and has simplicity and efficiency in execution. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd
Hell-Bent For Music: The Life of Pee Wee King
No full textPee Wee King\u27s birth on February 18, 1914, into a Milwaukee working-class Polish family named Kuczynski was hardly an indicator that he would grow up to become a pioneer and superstar of country and western music. Certainly no one in the Polish-German community of his youth could have foreseen his influence on the direction of American popular music or his enduring fame on the stage of the Grand Ole Opry. Even Pee Wee King himself is incredulous at the unlikely twists and turns of his life and career.
Pee Wee King is best remembered today as the co-writer of the most popular country music song of all time, The Tennessee Waltz. He is just as important, however, for his vital role in expanding the horizons, and the market potential, of country and western music. He took the polka and waltz rhythms of his youth, mixed them with the sounds of the big bands of the thirties and forties, and flavored it all with the balladry and moods of the Western cowboy. He combined this new sound with folk and country traditions rooted in places like Louisville, Knoxville, and Nashville. The result was a smooth, listenable, danceable, up-to-date sound that has become the most popular form of music in the United States.
Recipient of numerous awards, including induction into both the Songwriters Hall of Fame and the Country Music Hall of Fame, Pee Wee King has been one of the most important figures in country music for over sixty years. Told in King\u27s own voice and words, this biography, based on many hours of taped conversations, is the first account of King\u27s incredible life and career. Featuring a star-studded cast of characters from the history of music—Eddy Arnold, Minnie Pearl, Roy Acuff, Hank Williams, Gene Autry, Patti Page, and many others—this memorable book is a must-read for any fan of country music.
Wade Hall is professor of English at Bellarmine College and the author of numerous books, including The Rest of the Dream: The Black Odyssey of Lyman Johnson and Greetings from Kentucky: A Post Card Tour, 1900-1950.

Themanummer ‘COVID-19 en mobiliteit
No full textCOVID-19 is zeer snel een hot topic geworden in de wetenschappelijke literatuur over mobiliteitsgedrag. Er zijn inmiddels honderden papers over dit onderwerp verschenen. Ook in Nederland en Vlaanderen krijgt het onderwerp veel aandacht. Zo heeft het Kennisinstituut voor Mobiliteitsbeleid onder meer gepubliceerd over thuiswerken tijdens en na de coronacrisis (Hamersma et al., 2020), over de mobiliteitseffecten tijdens de pandemie (De Haas et al., 2020) en over de mogelijke impact op de toekomstige mobiliteit (Franke en Knoope, 2020). In Vlaanderen voert de Universiteit van Antwerpen periodiek grootschalig onderzoek uit over hoe mensen omgaan met de coronacrisis (Universiteit van Antwerpen, 2021). In het Tijdschrift Vervoerswetenschap is eerder gepubliceerd over mogelijke lange-termijn effecten op activiteiten- en mobiliteitsgedrag (Van Wee, 2020). Dit themanummer publiceert de resultaten van 8 recent in Nederland uitgevoerde onderzoeken. Vijf van de onderzoeken gaan over personenmobiliteit, en vloeien voort uit een interuniversitair onderzoeksprogramma (TU Delft en VU Amsterdam), gefinancierd door ZonMw (zie www.zonmw.nl). De beide resterende papers gaan over goederenvervoer.Transport and Logistic
An improvement of the Van Wee bound for binary linear covering codes
