2014 Future Cities Conference / Tânia Calçada & Daniel Moura "UrbanSense Platform"

  1. 1. UrbanSense Platform Tânia Calçada, Daniel Moura
  2. 2. UrbanSense Goals Understand and get aware of environmental and behaviour phenomena • Impact for the city • Research platform • Identify critical urban areas • Open data • Detect events in real time and automatically • Wireless networks testbed • Evaluate the impact of urban intervention actions • Data analysis and pattern recognition • Urban planning
  3. 3. Characteristics Sensor network – static and mobile • Hundreds of units • Wireless communications • 400 Mobile units in buses • Real-time transmission • Static units located down town • Opportunistic communications for delay tolerant data • Units with heterogeneous set of sensors • Local processing capacity • 550 environmental sensors • Count people and vehicles locally • 60 Video cameras • Adaptive sampling rate • 500 GPS, accelerometers, and On Board Devices
  4. 4. Sensors UrbanSense includes 600 sensor units. Hererogeneous sets of sensors. Meteorological • Temperature Relative Humidity • • Stand alone • VOC • 50 sensors (mobile and fixed) 75 sensors (mobile and fixed) • Azote Dioxide • • Pluviometer, Wind Vane Anemometer • 10 sensors (fixed) • 75 sensors (mobile and fixed) • Solar Radiation • 10 sensors (fixed) 75 sensors (mobile and fixed) • • • • 50 sensors (mobile and fixed) • Carbon Dioxide • • • GPS and Accelerometer • 50 sensors (mobile and fixed) 500 sensors (mobile) • OBD – On Board Device 50 sensors (mobile and fixed) • Carbon Monoxide 25 sensors (fixed) Mobility 75 sensors (mobile and fixed) • Particles PM10 High precision 1 sensor (fixed) • Embebed • Ozone (O3) • • Luminosity Noise Air Pollution Video • Cameras • 60 sensors (mobile and fixed)
  5. 5. Sensors Location Mobile units at buses roof Static units at Porto downtown
  6. 6. Perceiving people and vehicles anonymously Contours computed with RPi Local Processing = Anonymity & Light Communication At time 15:01 8 leaved 10 entered • • • • No video streaming No video storage Images described by statistics (descriptors) Low bandwidth requirements
  7. 7. Perceiving people and vehicles anonymously Sensing unit protype What can be done? • Counting people / vehicles • Classifying vehicles • Detecting patterns (e.g. crowding) Where? • Streets • Buildings • Public transports
  8. 8. Buses as City Scanners Frequency map Buses have city-wide coverage • Scanning the city using sensors • Detecting and predicting traffic jams • Characterizing mobility B A #vehicles / day >= 47 40 to 46 34 to 39 27 to 33 21 to 26 14 to 20 8 to 13 1 to 7 (Sample: 108 buses, Wed 27/Nov/2013)
