A Visual Analytics Framework for Large Transportation Datasets (CAADRIA 2014)

Conference: 19th International Conference on Computer-Aided Architectural Design Research in Asia CAADRIA 2014

Authors: Chen Zhong, Stefan Müller Arisona, Gerhard Schmitt

Abstract: The advancement of sensor technologies makes it possible to collect large amounts of dynamic urban data. On the other hand, how to store, process, and analyze collected urban data to make them useful becomes a new challenge. To address this issue, this paper proposes a visual analytics framework, which is applied to transportation data to manage and extract information for urban studies. More specif- ically, the proposed framework has three components: (1) a geographic information system (GIS) based pipeline providing basic data processing functions; (2) a spatial network analysis that is integrated into the pipeline for extracting spatial structure of urban movement; (3) interactive operations allowing the user to explore and view the output data sets at different levels of details. Taking Singapore as a case study area, we use a sample data set from the automatic smart card fare collection system as an input to our prototype tool. The result shows the feasibility of proposed framework and analysis method. To summarize, our work shows the potential of geospatial based visual analytics tools in using ‘big’ data for urban analysis.

The rise of new transdisciplinary practices in the late 20th and early 21st Centuries is striking. The gulf between art and science that has widened since the Enlightenment has now been challenged by a wide body of scholars, artists, designers and scientists. This special issue explores the concerns of emergent transdisciplinary research that seeks to re-unite the arts and sciences.

Multi-Projector-Mapper (MPM): Open-Source 3D Projection Mapping Software Framework

The multi-projector-mapper (MPM) is an open-source software framework for 3D projection mapping using multiple projectors. It contains a basic rendering infrastructure, and interactive tools for projector calibration. For calibration, the method given in Oliver Bimber and Ramesh Raskar’s book Spatial Augmented Reality, Appendix A, is used. Continue reading →

Visualizing Interchange Patterns in Massive Movement Data (EuroVis 2013)

Authors: Wei Zeng, Chi-Wing Fu, Stefan Müller Arisona, Huamin Qu

circos_multiscale

Abstract: Massive amount of movement data, such as daily trips made by millions of passengers in a city, are widely avail- able nowadays. They are a highly valuable means not only for unveiling human mobility patterns, but also for assisting transportation planning, in particular for metropolises around the world. In this paper, we focus on a novel aspect of visualizing and analyzing massive movement data, i.e., the interchange pattern, aiming at re- vealing passenger redistribution in a traffic network. We first formulate a new model of circos figure, namely the interchange circos diagram, to present interchange patterns at a junction node in a bundled fashion, and optimize the color assignments to respect the connections within and between junction nodes. Based on this, we develop a family of visual analysis techniques to help users interactively study interchange patterns in a spatiotemporal manner: 1) multi-spatial scales: from network junctions such as train stations to people flow across and between larger spatial areas; and 2) temporal changes of patterns from different times of the day. Our techniques have been applied to real movement data consisting of hundred thousands of trips, and we present also two case studies on how transportation experts worked with our interface.

Book: Digital Urban Modeling and Simulation

Edited by Stefan Müller Arisona, Gideon Aschwanden, Jan Halatsch, and Peter Wonka, 2012

About this Book

This book is thematically positioned at the intersections of Urban Design, Architecture, Civil Engineering and Computer Science, and it has the goal to provide specialists coming from respective fields a multi-angle overview of state-of-the-art work currently being carried out. It addresses both newcomers who wish to obtain more knowledge about this growing area of interest, as well as established researchers and practitioners who want to keep up to date. In terms of organization, the volume starts out with chapters looking at the domain at a wide-angle and then moves focus towards technical viewpoints and approaches. (Excerpt from preface by Stefan Müller Arisona).

ETH Zurich’s Singapore-ETH Centre and the Future Cities Laboratory

The Singapore-ETH Centre for Global Environmental Sustainability (SEC) in Singapore was established as a collaboration between the National Research Foundation of Singapore and ETH Zurich in 2010. It is an institution that frames a number of research programmes, the first of which is the Future Cities Laboratory (FCL). The SEC strengthens the capacity of Singapore and Switzerland to research, understand and actively respond to the challenges of global environmental sustainability. It is motivated by an aspiration to realise the highest potentials for present and future societies. SEC serves as an intellectual hub for research, scholarship, entrepreneurship, postgraduate and postdoctoral training. It actively collaborates with local universities and research institutes and engages researchers with industry to facilitate technology transfer for the benefit of the public. Continue reading →

The Value Lab Asia

The Value Lab Asia is a collaborative, digitally augmented environment for a wide range of applications, such as participatory urban planning and design, stakeholder communication, information visualisation and discovery, remote teaching and conferencing. It includes a 33 megapixel video wall, three large displays with touch overlays, a number of smaller, mobile multi-touch enabled displays, and extensive video conferencing capabilities. The Value Lab Asia is the younger sibling of the Value Lab Zurich, built at ETH Zurich’s ScienceCity by Gerhard Schmitt, Remo Burkhard, Jan Halatsch and Antje Kunze of the Chair of Information Architecture in 2007/08. It therefore borrows many of the concepts of the Value Lab Zurich, such as being set in a friendly environment that operates in daylight conditions, however comes with updated state-of-the-art hardware and a different look.

‘robot_mixeur’ is my alter ego when performing as visualist and DJ. As a DJ, I usually mix elements from minimal techno, tech house and techno into driving soundscapes and pushing beats. As a visualist (or VJ), I am using the self-coded software Soundium/Decklight as performance environment for live video editing and 3D content generation. Continue reading →
