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.

Projections of Reality engages in augmenting design processes involving physical models with real time spatial analysis. The work was initiated at smartgeometry'13 at UCL London in April 2013 and is currently continued at ETH Zurich’s Value Lab Asia in Singapore.

The work explores techniques of real time spatial analysis of architectural and urban design models: how physical models can be augmented with real-time 3D capture and analysis, enabling the architect to interact with the physical model whilst obtaining feedback from a computational analysis. We investigate possible workflows that close the cycle of designing and model making, analysing the design and feeding results back into the design cycle by projecting them back onto the physical model.

On a technical level, we are addressing the challenge of dealing with complex, unstructured data from real time scanning, e.g. a point cloud, which needs processing before it can be used in urban analysis. We will investigate strategies to extract information of the urban form targeted for design processes, using real time scanning devices (Microsoft Kinect, hand held laser scanners, etc.), open source 3D reconstruction software (reconstructMeQT) and post-processing of the input through parametric modelling (e.g. Processing, Rhino scripting, Generative Components).

The goal of the workshop at smartgeometry'13 was to create a working prototype of a physical urban model that is augmented with real-time analysis. We worked with the cluster participants to formulate a design concept of the prototype and to break down the challenge into individual modules, e.g. analysing and cleaning the geometry, algorithms for real time analysis, projecting imagery onto the physical model.

The energy scenario planning tool, developed by Eva Friedrich, has been presented at the ADDIS 2050 conference in Addis Ababa on October 9th and 10th 2012. The basic concept of the work is to create an intuitive and playful tool that allows for collaborative, interactive exploration of possible energy supply and consumption scenarios in Ethiopia. The users can move in time and compare different approaches to energy development in their effect: centralized hydro power, less-centralized wind power with local support, and completely decentralized solar power for rural, disconnected areas - thereby obtaining a better understanding of the effects of mid- to long-term energy planning.

The tool’s interface is built in a minimal style in order to keep the focus on the relevant points. It supports multi-touch surfaces, and borrows concepts from game engines, e.g. physics based animations for connecting networks.

The conference ADDIS 2050 – an alternative pathway into Ethiopia’s future – was held on October 9th and 10th 2012 at the campus of the Ethiopian Institute of Architecture, Building Construction and City Development EiABC in Addis Ababa. Addis Ababa belongs to the fastest growing urban centers in the world. Migration from the rural areas as well as massive redevelopment strategies of the City Government put the African capital under enormous pressure. Infrastructural deficiencies, water and energy shortages, environmental hazards and mobility challenges question the current modus operandi in place.

The Green Forum Ethiopia under the leadership of Heinrich Boell Foundation in Addis Ababa commissioned the Chair of Architecture and Construction Dirk E. Hebel at FCL Singapore in collaboration with the Ethiopian Institute of Architecture, Building Construction and City Development EiABC to invent an alternative “green” scenario for the city of Addis Ababa in the year 2050. The conference concentrated on the issues of Energy, Mobility, Cultural and Social Space, Housing and Information. The event was visited by more than 500 people and arose immense interest from the media as well as the City Administration. As guest of honor, the Swiss Ambassador H.E. Dominik Langenbacher attended the conference as well as delegates from several federal ministries and the UN-Habitat. In the meantime, the Department of Masterplanning and Vision of the City Adeministration invited the speakers to present the work in their offices.
