  1. The MESSAGE ProjectMobile Environmental Sensing System Across a Grid Environment Professor John Polak Director, Centre for Transport Studies Imperial College London j.polak@imperial.ac.uk www.message-project.org

  2. Outline • Background and motivation • Overview • Challenges and innovation • Field trials • Conclusion

  3. MESSAGE - headlines • 3 year project starting October 2006 • Funded jointly by EPSRC and DfT under EPSRC’s e-Science demonstration programme • 5 Universities, 19 industrial partners • Combination and extension of e-Science, sensor, communication and positioning technologies • New sensing infrastructure based on combination of ad-hoc mobile and fixed sensors

  4. MESSAGE – collaboration

  5. MESSAGE - motivation • Urban air quality is a major policy concern, especially the role of road transport • Understanding vehicle emissions • Understanding human exposure • Managing network operations to optimise congestion and air quality outcomes • Research and practice is hampered by lack of data of sufficient spatial and temporal granularity • Opportunity to capitalise on low cost sensor, positioning and communications technologies

  6. MESSAGE – overview Heterogeneous fixed and mobile sensors on infrastructure, vehicles and people Sensors communicate via wireless networks Positioning via GPS + wireless & cellular ranging Integration of processing along the data path Multiple application studies in different local contexts

  7. MESSAGE – multi-disciplinarity MESSAGE involves integrating academic expertise from several disciplines: 1Transport network modellers Air quality modellers Geomatricians Computer Scientists Electrical Engineers Sensor Developers (Physicists and Chemists) Together with industry experience and tangible real-world applications

  8. MESSAGE – research challenges Field units Sensors Positioning Communications e-Science Scalability Distributed data mining Online estimation of pollutant hotspots Transport and environment modelling Traffic management and control Traveller information

  9. MESSAGE – field units We are deliberately deploying a variety of different sensor, positioning and communications technologies, to ensure that the MESSAGE system is generic

  10. MESSAGE – e-Science challenge We will build on the foundation of past e-science projects (DiscoveryNet and OGSA-DAI): Grid-enabled sensor service (a sensor is a service generating data) Semantically-described sensors (Sensor-ML) Sensor data collection and warehousing Querying distributed data storage Workflow based analysis of sensor data New challenge: Scalable distributed analytics for pervasive mobile heterogeneous sensors

  11. MESSAGE – e-Science innovation Development of sensor-level protocols to support in-network analytics Development of real-time in-network analytics Associated extensions of Discovery Net to support in-network analytics

  12. MESSAGE – modelling innovation Existing transport and air quality models have a simple centralised architecture Need to evolve new forms of interpretive and predictive transport models accommodate multiple data sources and scales and levels of behavioural richness support distributed architectures Must stimulate academic and commercial innovation in tool and service development and deployment

  13. MESSAGE – architecture

  14. MESSAGE – case studies

  15. MESSAGE – London case study • Imperial and Newcastle sensor units • Buses, fleet vehicles and street furniture • Mobile deployment of heterogeneous systems • Integration with existing TfL data streams • Feedback to traffic management

  16. MESSAGE – London test site • Camden High St. • Multiple bus types • Candidate routes • 29 • 31 • 88 • 168 • 274

  17. Opportunities MESSAGE is concerned with integrating a number of technologies and approaches from within the e-Science community and beyond Although our context is urban air quality, the concept of pervasive mobile sensing has much wider application Other application areas are being actively developed
