Governance of future urban mobility: a research agenda
No full textQuestions about how to plan and govern for future urban mobility are reaching a critical point as Australian cities are faced with disruption to transport and urban systems arising from new forms of shared mobility services and the rise of autonomous vehicles. An industry engagement workshop, drawing on the insights of participants from public and private sectors of the industry, articulated a large array of complex and interrelated questions highlighting the uncertainty and scarcity of knowledge. These questions are grouped into three key themes concerning how implementation may take place, what the impacts of the uptake of these emerging transport technologies may be and how to understand them. The resultant research agenda is vast and one of multi-complexity by space, time and institutionally
Planning the driverless city
Get PDFAV technologies have the potential to transform urban landscapes and existing transport systems and networks. Yet, the utopian imaginary of reduced automobile ownership and a new shared economic future sits in tension with suggestions that car dependency, urban sprawl and transport inaccessibility will be exacerbated. The issues are situated in a complex governance landscape involving an influential private sector who are increasingly setting the agenda. The public sector may be forced into reacting to the new innovations by information technology and automobile companies as they are introduced into existing built environments. Drawing on an extensive literature base and interviews with public sector planners, this paper reveals the conceptual gaps in the framing of AV technology – the prospects and limits – and how these are conceived. The paper raises questions about the role urban planning can play in the rollout of AVs in order to anticipate and mediate unwanted built environment and socio-spatial impacts, as well as reconciling the ambition of transport innovation with the public purpose of planning
Planning for disruptive transport technologies: how prepared are Australian transport agencies?
No full textIn Australia, corporations are playing an increasing role in the shaping of urban regions through their ability to mobilize capital to support large infrastructure projects and to usurp institutional planning roles which have traditionally been the responsibility of public-sector agencies. The chapter outlines emerging evidence of changes in the roles of corporations in generating ideas and mobilizing political support for their favoured city-shaping projects, and shows that the private sector is embedded in the processes of government, such as planning, in increasingly complex ways. Through ‘market-led’ or ‘unsolicited’ proposal evaluation frameworks, corporations can now bring proposals to political leaders in ways which go outside traditional planning processes and bypass conventional engagement with civil society.In this context, we present data from a recent survey of planners in state and national land-use and transport agencies. The survey, conducted through semi-structured interviews, gathered information about the expectations of these organizations in relation to the nature and timing of the deployment of new AV technologies; about the potential implications for achieving environmental and social planning objectives; and about the collective infrastructure investments that AV technologies may require. This work is being used to shape a new research agenda to explore the planning and regulatory frameworks that are needed to ensure that the AV technologies can be deployed in ways that maximize the public good.<br/
Challenges for Government as Facilitator and Umpire of Innovation in Urban Transport: The View from Australia
Get PDFAbstract
New economies based on emerging technologies for shared mobility and autonomous vehicles will shape future urban transport systems, but their potential impacts are uncertain. Internationally, government agencies face difficult challenges to effectively plan and regulate the deployment of these technologies for the common good, whilst simultaneously encouraging innovation. Being both a facilitator and an umpire is not an easy task. This chapter draws on a series of interviews with public and private-sector actors in urban transport in Australia. Unsurprisingly, all private-sector respondents had significant concerns for the sustainability of their business in the emerging mobility markets, but it was generally acknowledged that without government support and partnership, a lack of structure and clarity could lead to natural monopolies with negative consequences for competition and the public good. Strong and clear government regulation is seen to be necessary to allow the sector to reach its maximum potential and have positive ramifications for both the public and the private good – outcome not always seen as compatible. Public-sector interviewees generally recognised that much of the necessary innovation was being shaped by the market, and that there had been a considerable loss of skills over decades from the state because of neo-liberal policies. So, some doubted the ability of the state to shape developments using currently available planning and public policy methods and feared that it would be difficult to regulate emergent markets to prevent monopolies emerging. On the other hand, some argued that many firms are looking to government for frameworks in which businesses can operate successfully by setting conditions in which risks could be managed. This chapter discusses these issues, seeking to guide research agendas and to foster further debate. The evidence gained from these in-depth interviews helps focus attention on which forms of regulation might be required by industry. It also raises questions about the capacity of government agencies to effectively manage these complex transitions
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
