NTNU Delegation Smart Cities - Visit to DTU

  1. 1. Rector’s Visit DTU – NTNU Delegation Smart Cities Dirk Ahlers NTNU IDI (Institutt for datateknikk og informasjonsvitenskap)
  2. 2. 2 Research on Smart Cities and related areas at NTNU–IDI • Contribution to NTNU SmartCities https://www.ntnu.edu/smartcities • IME Lighthouse on Open Autonomous Digital Ecosystems - http://www.ntnu.edu/ime/oade (Computer Science, Electrical Engineering, Telematics), also SmartGrids • IME Lighthouse on Big Data http://www.ntnu.edu/ime/bigdata • HCI research in behaviour and Smart Meters • Mobility
  3. 3. 3 Open and Autonomous Digital Ecosystems (OADE)
  4. 4. 4 Campus Guide, MazeMap • Campus as a Living Lab • Member of ENoLL – European Network of Living Labs • Cisco WLAN-positioning on Campus and in the city
  5. 5. 5 Infrastructure Setup • Mobility data with high spatial and temporal resolution • WLAN indoor coverage on campus • Passive location sensing, WLAN trilateration • Device positions as proxy for people’s locations • Sampling bias and double counting addressed in future work for improved accuracy • Data contains anonymized ID, timestamp, coordinates, accuracy, derived hierarchy – e.g. Gloshaugen > IT-Vest > 1. etasje, Gloshaugen > Sentralbygg II > 13. etasje
  6. 6. 6 Stacked movement abstraction • Position Gathering • Abstraction and processing layers – Data cleaning/preprocessing – Movement Extraction – Building-graph extraction • Visualization
  7. 7. 7 Estimates are useful
  8. 8. 8 Mobility vs Search [Navigating MazeMap: indoor human mobility, spatio- logical ties and future potential, IEEE, 2014]
  9. 9. 9 Future work: Outdoor city mobility [Thomas Jelle, Big Data and Smart Cities]
  10. 10. 10 Conclusion • Awareness and planning support of building use • Real-time availability of rooms and facilities • Connection to larger mobility • Sustainable campus and city • Scaling out
