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 sixth in this series building upon the successful previous five PURBA 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 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.

Keynote Talk
by Professor Archan Misra, the Associate Dean of Research, the School of Information Systems at Singapore Management University (SMU)

The Role of Individual & Aggregated Urban Mobility in Smart City Services
This talk will describe how we utilize a combination of data from personal mobile devices, urban informatics portals, public social media and infrastructural sensors to usher in a new wave of “smart city” applications and services. First, I will highlight our work on mobile crowdsourcing, where we have ongoing national-level trials on using predicted movement patterns of city residents to support the concept of active citizenry. Under this concept, resident volunteers help monitor municipal resources, support community-centric services and can even help with last-mile logistics tasks.  Next, as an exemplar of how urban mobility and social media data can be jointly used for urban planning, I shall describe our work on predicting the survivability of urban retail businesses and the economic vitality of city neighborhoods. Such data sets can also be used to offer micro-and-macro insights into urban events. As a final example, I will demonstrate how fusing personalized and aggregated analytics of commuting data can help support optimized allocation of last-mile transportation resources.
