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

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

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

Stacked movement abstraction

• Position Gathering• Abstraction and processing layers

– Data cleaning/preprocessing– Movement Extraction– Building-graph extraction

• Visualization

7

Estimates are useful

Mobility vs Search

[Navigating MazeMap: indoor human mobility, spatio-logical ties and future

potential, IEEE, 2014]

9

Future work: Outdoor city mobility

[Thomas Jelle, Big Data and Smart Cities]

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
