Transport visions: vehicles and infrastructure
This is the fourth in a series of reports to be produced by the Transport Visions Network. The Network is a novel venture to project the views of young professionals into the debate concerning the future of transport and its role in society. It is comprised of individuals who are aged 35 or under from universities, consultancies and public authorities both in the UK and overseas.This report examines how vehicles and infrastructure might be used to develop the UK’s surface transport networks of the future. In doing so, it has attempted to highlight the balance between maintaining existing systems and making the best use of technological advances to develop new vehicles and new systems. Technological advances offer the opportunity to increase the capacity that any system of infrastructure can provide. Preferably technology should be harnessed to develop systems that increase the number of people per hour that we move rather than the number of vehicles per hour. Measures such as dedicated lanes and intelligent charging can facilitate this. Similarly, greater support for car sharing and innovative forms of shared vehicle ownership could help achieve such aims. The improvements in throughput in people per hour achieved through these measures may also deliver vastly enhanced energy efficiency per kilometre moved
Society and Lifestyles
This report on ‘Society and Lifestyles’ recognises that changes in the fabric of society and its set values can have a profound impact on travel demand and transport. Transport professionals must be mindful of the outward integration of transport with employment, business practices, standard of living, households, education, social values etc. as well as integration within transport. The report seeks to raise awareness regarding the diversity of factors that will directly or indirectly influence future travel demand
Towards a real-time microscopic emissions model
This article presents a new approach to microscopic road traffic exhaust emission modelling. The model described uses data from the SCOOT demand-responsive traffic control system implemented in over 170 cities across the world. Estimates of vehicle speed and classification are made using data from inductive detector loops located on every SCOOT link. This data feeds into a microscopic traffic model to enable enhanced modelling of the driving modes of vehicles (acceleration, deceleration, idling and cruising). Estimates of carbon monoxide emissions are made
by applying emission factors from an extensive literature review. A critical appraisal of the development and validation of the model is given before the model is applied to a study of the impact of high emitting vehicles. The article concludes with a discussion of the requirements for the future development and benefits of the
application of such a model
The case of Mobility as a Service: A critical reflection on challenges for urban transport and mobility governance
This chapter provides a reflective critique of Mobility as a Service (MaaS), an emerging development seeking a role within the Smart Mobility paradigm. We assess a range of its future implications for urban policymakers in terms of governance and sustainability (i.e., social and environmental impacts). We begin by describing the origins of the MaaS concept, along with the features of precursor technologies and current early examples. We then reflect on the marketing of MaaS and use it to consider how we might anticipate some potentially less desirable aspects of the promoted business models. Finally, we discuss the implications for governance.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.Spatial Planning and StrategyTransport and Plannin
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
