This book was released on 2017 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic congestion is a major concern that many urban regions contend with. Since the 1970s, transport practitioners have sought out different ways to alleviate the negative impacts of congestion. The concept of Transportation Demand Management (TDM) was born out of this era as a means to address congestion through demand-side approaches that encourage adjustments in travel behaviour. Given its broad mandate, a wide variety of policies and programs fall within the realm of TDM. To assist in the selection of appropriate TDM strategies prior to implementation, several TDM evaluation models have been developed. However, many analysis techniques require data from past examples of TDM strategy implementation, which are at times difficult to obtain, and would not be available for newly developed and untested policy and program approaches. This thesis builds on the techniques used in past models to present a new model framework that can be used in the identification and evaluation of opportunities to apply TDM strategies. Employing a pivot-point logit model, the model relies only on quantifications of traveller utility through generalized cost calculations. Crowdsourced travel data collected from the Google Maps web-mapping application has been used as the primary source of data behind the generalized costs. The model was applied to a set of test corridors in the Greater Toronto and Hamilton Area (GTHA) which represent major cross regional travel flows. Results of the model were found to be directionally consistent with known conditions of the transportation system in the study area, though adjustments are needed to the model coefficients in order to more accurately reflect the magnitude of behavioural change to be expected from travellers.
Download or read book Analysis of Travel Patterns from Cellular Network Data written by Nils Breyer and published by Linköping University Electronic Press. This book was released on 2019-05-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic planners are facing a big challenge with an increasing demand for mobility and a need to drastically reduce the environmental impacts of the transportation system at the same time. The transportation system therefore needs to become more efficient, which requires a good understanding about the actual travel patterns. Data from travel surveys and traffic counts is expensive to collect and gives only limited insights on travel patterns. Cellular network data collected in the mobile operators infrastructure is a promising data source which can provide new ways of obtaining information relevant for traffic analysis. It can provide large-scale observations of travel patterns independent of the travel mode used and can be updated easier than other data sources. In order to use cellular network data for traffic analysis it needs to be filtered and processed in a way that preserves privacy of individuals and takes the low resolution of the data in space and time into account. The research of finding appropriate algorithms is ongoing and while substantial progress has been achieved, there is a still a large potential for better algorithms and ways to evaluate them. The aim of this thesis is to analyse the potential and limitations of using cellular network data for traffic analysis. In the three papers included in the thesis, contributions are made to the trip extraction, travel demand and route inference steps part of a data-driven traffic analysis processing chain. To analyse the performance of the proposed algorithms, a number of datasets from different cellular network operators are used. The results obtained using different algorithms are compared to each other as well as to other available data sources. A main finding presented in this thesis is that large-scale cellular network data can be used in particular to infer travel demand. In a study of data for the municipality of Norrköping, the results from cellular network data resemble the travel demand model currently used by the municipality, while adding more details such as time profiles which are currently not available to traffic planners. However, it is found that all later traffic analysis results from cellular network data can differ to a large extend based on the choice of algorithm used for the first steps of data filtering and trip extraction. Particular difficulties occur with the detection of short trips (less than 2km) with a possible under-representation of these trips affecting the subsequent traffic analysis.
Download or read book Travel Demand Management and Road User Pricing written by Gerd Sammer and published by Routledge. This book was released on 2016-02-24 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the world, traffic levels are increasing and, in urban areas, these increasing levels have led to pressures on the road networks which are causing serious economic, environmental and social problems. This book examines the full range of 'push and pull' Travel Demand Management measures. This covers areas of regulatory, pricing, planning and persuasive policies to encourage individuals to make their trips in off-peak periods, by a different mode or to find another way of carrying out the trip purpose. Applying such measures can result in a more efficient transport system, improved environmental conditions and improvements in safety as well as revenue generation for use on alternative transport systems. The editors conclude with a summary of findings within the book and suggestions for best future practice.

Download or read book Crowdsourcing Geographic Knowledge written by Daniel Sui and published by Springer Science & Business Media. This book was released on 2012-08-10 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of volunteered geographic information is part of a profound transformation in how geographic data, information, and knowledge are produced and circulated. By situating volunteered geographic information (VGI) in the context of big-data deluge and the data-intensive inquiry, the 20 chapters in this book explore both the theories and applications of crowdsourcing for geographic knowledge production with three sections focusing on 1). VGI, Public Participation, and Citizen Science; 2). Geographic Knowledge Production and Place Inference; and 3). Emerging Applications and New Challenges. This book argues that future progress in VGI research depends in large part on building strong linkages with diverse geographic scholarship. Contributors of this volume situate VGI research in geography’s core concerns with space and place, and offer several ways of addressing persistent challenges of quality assurance in VGI. This book positions VGI as part of a shift toward hybrid epistemologies, and potentially a fourth paradigm of data-intensive inquiry across the sciences. It also considers the implications of VGI and the exaflood for further time-space compression and new forms, degrees of digital inequality, the renewed importance of geography, and the role of crowdsourcing for geographic knowledge production.
Download or read book Urban Informatics written by Wenzhong Shi and published by Springer Nature. This book was released on 2021-04-06 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.
Download or read book Incomplete Streets written by Stephen Zavestoski and published by Routledge. This book was released on 2014-08-27 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ‘Complete Streets' concept and movement in urban planning and policy has been hailed by many as a revolution that aims to challenge the auto-normative paradigm by reversing the broader effects of an urban form shaped by the logic of keeping automobiles moving. By enabling safe access for all users, Complete Streets promise to make cities more walkable and livable and at the same time more sustainable. This book problematizes the Complete Streets concept by suggesting that streets should not be thought of as merely physical spaces, but as symbolic and social spaces. When important social and symbolic narratives are missing from the discourse and practice of Complete Streets, what actually results are incomplete streets. The volume questions whether the ways in which complete streets narratives, policies, plans and efforts are envisioned and implemented might be systematically reproducing many of the urban spatial and social inequalities and injustices that have characterized cities for the last century or more. From critiques of a "mobility bias" rooted in the neoliberal foundations of the Complete Streets concept, to concerns about resulting environmental gentrification, the chapters in Incomplete Streets variously call for planning processes that give voice to the historically marginalized and, more broadly, that approach streets as dynamic, fluid and public social places. This interdisciplinary book is aimed at students, researchers and professionals in the fields of urban geography, environmental studies, urban planning and policy, transportation planning, and urban sociology.

Download or read book The Fourth Industrial Revolution written by Klaus Schwab and published by Currency. This book was released on 2017-01-03 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: World-renowned economist Klaus Schwab, Founder and Executive Chairman of the World Economic Forum, explains that we have an opportunity to shape the fourth industrial revolution, which will fundamentally alter how we live and work. Schwab argues that this revolution is different in scale, scope and complexity from any that have come before. Characterized by a range of new technologies that are fusing the physical, digital and biological worlds, the developments are affecting all disciplines, economies, industries and governments, and even challenging ideas about what it means to be human. Artificial intelligence is already all around us, from supercomputers, drones and virtual assistants to 3D printing, DNA sequencing, smart thermostats, wearable sensors and microchips smaller than a grain of sand. But this is just the beginning: nanomaterials 200 times stronger than steel and a million times thinner than a strand of hair and the first transplant of a 3D printed liver are already in development. Imagine “smart factories” in which global systems of manufacturing are coordinated virtually, or implantable mobile phones made of biosynthetic materials. The fourth industrial revolution, says Schwab, is more significant, and its ramifications more profound, than in any prior period of human history. He outlines the key technologies driving this revolution and discusses the major impacts expected on government, business, civil society and individuals. Schwab also offers bold ideas on how to harness these changes and shape a better future—one in which technology empowers people rather than replaces them; progress serves society rather than disrupts it; and in which innovators respect moral and ethical boundaries rather than cross them. We all have the opportunity to contribute to developing new frameworks that advance progress.
