Welcome to PURBA 2015

The 4th International Workshop on Pervasive Urban Applications

In conjunction with the 2015 ACM International Joint Conference on Pervasive and Ubiquitous Computing (UbiComp 2015)

icon PURBA 2011

The first workshop on Pervasive Urban Applications (PURBA 2011) was held in conjunction with PERVASIVE 2011 in San Francisco, USA.

icon PURBA 2012

The second workshop on Pervasive Urban Applications (PURBA 2012) was held in conjunction with PERVASIVE 2012 in Newcastle upon Tyne, UK.

icon PURBA 2013

The third workshop on Pervasive Urban Applications (PURBA 2013) was held in conjunction with UbiComp 2013 in Zurich, Switzerland.

Over the past decade, the development of digital networks and operations has produced an unprecedented wealth of information. Handheld electronics, location devices, telecommunications networks, and a wide assortment of tags and sensors are constantly producing a rich stream of data reflecting various aspects of urban life. For urban planners and designers, these accumulations of digital traces are valuable sources of data in capturing the pulse of the city in an astonishing degree of temporal and spatial detail. Yet this condition of the hybrid city – which operates simultaneously in the digital and physical realms – also poses difficult questions about privacy, scale, and design, among many others. These questions must be addressed as we move toward achieving an augmented, fine-grained understanding of how the city functions – socially, economically and yes, even psychologically.


This workshop is the forth in this series building upon the successful PURBA-2011, PURBA-2012, and PURBA-2013 workshops. It aims to bring together researchers and practitioners to discuss and explore the research challenges and opportunities in applying the pervasive computing paradigm to urban spaces.

We are seeking multi- disciplinary contributions that reveal interesting aspects about urban life and exploit the digital traces to create novel urban applications that benefit citizens, urban planners, and policy makers. The PURBA-2015 workshop fosters discussions covering topics such as (but not limited to):

• Pervasive computing applications for urban planning and design
• Mining of data collected from urban networks e.g. transportation, energy
• Urban mobility and geo-localization
• Multi-source urban information integration
• Real-time urban information processing
• City-related knowledge infrastructure and computational models
• Case studies and applications of mixed urban sensing and mining
• Analysis of social networks in urban space
• Middleware for mobile urban computing
• Context-aware systems for urban space
• Smart cities
• Intelligent transportation system
• Urban application demos and visualizations
• Wireless sensor networks, mobile devices, and social network sensing
• Security, privacy, reputation, and trust issues in urban computing
• Impact of pervasive technologies in urban space e.g. social, economical, and psychological.

Important Dates
Paper submission: 8 June 2015 (extended)
Paper notification: 1 July 2015
Camera-ready: 8 July 2015
Workshop: 7 September 2015

We welcome regular (up to 9 pages) and short (up to 5 pages) paper contributions submitted as PDF files. The workshop accepts manuscripts in SIGCHI Extended Abstracts Format. The accepted papers will be published in the Ubicomp 2015 adjunct proceedings, which will be included in the ACM Digital Library and indexed by SCOPUS. Visionary and position papers are encouraged. All contributions must not have been previously published or be under consideration for publication elsewhere. All submitted papers will be reviewed and judged on originality, technical correctness, relevance, and quality of presentation by the Program Committee. All accepted submissions must be presented during the workshop.

Bell-Labs Best Paper Award
The Bell-Labs Best Paper Award is given to the best paper presented at the PURBA 2015 workshop, to acknowledge and encourage excellence in research. The awardee will be presented with a certificate and a monetary award at the workshop.
