A survey on Human Mobility and its applications

Human Mobility has attracted attentions from different fields of studies such as epidemic modeling, traffic engineering, traffic prediction and urban planning. In this survey we review major characteristics of human mobility studies including from trajectory-based studies to studies using graph and network theory. In trajectory-based studies statistical measures such as jump length distribution and radius of gyration are analyzed in order to investigate how people move in their daily life, and if it is possible to model this individual movements and make prediction based on them. Using graph in mobility studies, helps to investigate the dynamic behavior of the system, such as diffusion and flow in the network and makes it easier to estimate how much one part of the network influences another by using metrics like centrality measures. We aim to study population flow in transportation networks using mobility data to derive models and patterns, and to develop new applications in predicting phenomena such as congestion. Human Mobility studies with the new generation of mobility data provided by cellular phone networks, arise new challenges such as data storing, data representation, data analysis and computation complexity. A comparative review of different data types used in current tools and applications of Human Mobility studies leads us to new approaches for dealing with mentioned challenges

Revealing intra-urban spatial structure through an exploratory analysis by combining road network abstraction model and taxi trajectory data

The unprecedented urbanization in China has dramatically changed the urban spatial structure of cities. With the proliferation of individual-level geospatial big data, previous studies have widely used the network abstraction model to reveal the underlying urban spatial structure. However, the construction of network abstraction models primarily focuses on the topology of the road network without considering individual travel flows along with the road networks. Individual travel flows reflect the urban dynamics, which can further help understand the underlying spatial structure. This study therefore aims to reveal the intra-urban spatial structure by integrating the road network abstraction model and individual travel flows. To achieve this goal, we 1) quantify the spatial interaction relatedness of road segments based on the Word2Vec model using large volumes of taxi trip data, then 2) characterize the road abstraction network model according to the identified spatial interaction relatedness, and 3) implement a community detection algorithm to reveal sub-regions of a city. Our results reveal three levels of hierarchical spatial structures in the Wuhan metropolitan area. This study provides a data-driven approach to the investigation of urban spatial structure via identifying traffic interaction patterns on the road network, offering insights to urban planning practice and transportation management

A Survey of Volunteered Open Geo-Knowledge Bases in the Semantic Web

Over the past decade, rapid advances in web technologies, coupled with innovative models of spatial data collection and consumption, have generated a robust growth in geo-referenced information, resulting in spatial information overload. Increasing 'geographic intelligence' in traditional text-based information retrieval has become a prominent approach to respond to this issue and to fulfill users' spatial information needs. Numerous efforts in the Semantic Geospatial Web, Volunteered Geographic Information (VGI), and the Linking Open Data initiative have converged in a constellation of open knowledge bases, freely available online. In this article, we survey these open knowledge bases, focusing on their geospatial dimension. Particular attention is devoted to the crucial issue of the quality of geo-knowledge bases, as well as of crowdsourced data. A new knowledge base, the OpenStreetMap Semantic Network, is outlined as our contribution to this area. Research directions in information integration and Geographic Information Retrieval (GIR) are then reviewed, with a critical discussion of their current limitations and future prospects

Constant's Nomadic City

In the period 1954-1974 the Dutch artist known as Constant (Constant Nieuwenhuys, 1920-2005) elaborated a series of artworks and writings depicting a future urban agglomeration: New Babylon. Stretching over the whole globe, New Babylon hosts wandering individuals who freely move around the interactive space of the hyper-city without any fixed abode, or any reference to an established culture and habits. As the progressing automation of all productive activity allows the people to dispose of free time without any limitation, the main activities of New Babylonians are of a ludic kind. After a concise introduction, this article concentrates on the written work accompanying the project, by focusing on two recurring key terms: “nomadism” and “play”. These are the “travelling concepts” (Bal 2002) surfacing in a number of texts by other authors, diverse in scope, disciplinary field, and date of composition. Next to Deleuze and Guattari’s Nomadologie (Mille plateaux, 1980), Edouard Glissant’s Poétique de la Relation (1990), Johan Huizinga’s Homo Ludens (1938), the net of relations among texts outlined in this article comes to encompass also Dutch authors such as Menno ter Braak (1902-1940) and Simon Vinkenoog (1928-2009), with the aim of reconnecting New Babylon with its Dutch background, too often underplayed in scholarship on this subject. Urban planning, social trends and the development of counter-cultures in the Netherlands in the Fifties and Sixties offer a better insight into Constant’s internationally revered artwork

Leveraging Change: Increasing Access to Arts Education in Rural Areas

In 2015, Massachusetts College of Liberal Arts (MCLA) received funding in the first round of collective impact grants from the National Endowment for the Arts to launch the pilot initiative, Leveraging Change: Improving Access to Arts Education in Rural Areas. The authors conducted research which included a literature review and interviews with arts education leaders in rural areas. Using the research compiled through this process, a pilot convening was held in western Massachusetts' Berkshire County to activate ideas, stimulate the exchange of information, and generate cross-sector collaboration focused on strengthening support for arts education in the region. This working paper is a summary of the research results and insights gleaned from this pilot initiative

Creating Low-carbon Communities: Evaluating the Role of Individual Agency and Systemic Inequality in San Jose, CA

Following a scholarly need to test compelling community level sociodemographic representations of environmental behaviors and outcomes, a sequential mixed method approach was used to evaluate the connections of human agency and systemic inequalities with carbon footprints. Statistical analyses of the 2016 SDG San Jose Dashboard data of city blocks and 2009 - 2013 ACS survey data were supplemented with interviews with eight climate action-oriented community engagement professionals in the South Bay. Boundary limiting socioeconomic conditions for systemic inequalities and human agency, dimensions of Gidden’s Structuration model, were specified. Partially supporting structural inequality theories, socioeconomic resources, primarily, and to a lesser extent dominant race concentration, were associated with larger carbon footprints, particularly when wealth was concentrated. Both human (time driven alone) and demographic (senior and mid-aged blocks) agencies were also in part at play in shrinking or even enlarging carbon footprints, in wealthier communities. These findings not only contributed to the literature on climate action, but also highlighted the need for targeted interventions in communities of different socioeconomic standing
