OrganiCity Experimenter Workshop Slidedeck

  1. 1. OrganiCity Experimenters #organicity @AirPublica Air Quality & Urban Mobility
  2. 2. The challenge
  3. 3. ? Solutions
  4. 4. Our Monitoring Solution Challenge ● 120 static monitors in London ● Modelled data in between ● Static monitors cost £10-20k just to install
  5. 5. Our Monitoring Solution
  6. 6. Potential ● Front end ● International opportunities ● Integration into smart city infrastructure ● Co-creation
  7. 7. Aims ● Refine the existing prototype to integrate with electric delivery vans ● Integrate with the OrganiCity platform and test the facility ● Validate assumptions in our proposed system; ○ Using multiple lower quality sensors to produce accurate, granular air quality data ○ Host on moving agents to produce a good spread of data points ● Engage citizen stakeholders to co-create throughout experiment
  8. 8. Hardware
  9. 9. Hardware Microcontroller Sensors: CO NO2 PM(1-10μm) Temperature Humidity GPS GSM Fuse + Voltage regulator etc Pump Air intake Power (12v dc) Antenna Antenna
  10. 10. Asset JSON structure
  11. 11. Asset = Device or data point? We have 10 devices which move We have >90k data points with valid GPS Organicity currently only allows 1k assets per experiment Asset as device => Only see 10 data points Asset as data point => Limitations reached

  16. 16. Sensinact studio
  17. 17. Data Density
  18. 18. Comparing our results to London Annual map We compiled places where we got 20 readings or more, averaged readings and compared them to the London Annual mean map. Figure on the right is NO2 levels from a single van, spots represent 20x20m squares. Green is good, yellow is high and red is bad. One can see that we highlight most of the road intersections as yellow, with some red. Disclaimer: not calibrated data yet.
  19. 19. Quality assurance of the devices Unfortunately the hardware has turned out to be quite delicate with devices frequently going out of order. We monitored them over 48 hours to find which one work and which ones don’t. Only four out of 10 boxes have turned out to be perfect, the rest needed further work.
  20. 20. Torching temp and humidity
  21. 21. All 10 sensors register high NO2 levels during calibration torching
  22. 22. Co-creation Citizen Co-creators
  23. 23. Conclusions ● For novel data sets and systems integration is key; ● Co-creation is an essential process for citizen centric experimentation. ● Device development in parallel with platform development presented challenges and opportunities ● Stepped development is crucial for innovative hardware development ● Concepts of calibration between sensors and data density proven
  24. 24. TrafficFlow - Analytics for smarter cities Fabrizio Dini -
  25. 25. Traffic data are key for truly smart cities Planning: ● Viability design ● Introduction of 30 Km/h speed limit ● Pollution level control Operation: ● Measure behavior changes ● Adaptive traffic light timing Public information: ● Periodic traffic report (web, radio, tv) ● Early alert
  26. 26. TrafficFlow Result of several EU co-funded projects in 2012-2016 (ORUSSI, CHEST, SOUL-FI/Floud, SME Instrument) Low cost traffic-monitoring sensor for participative data collection campaigns ● Requires little to no infrastructure ● Easy to install and configure ● Suitable for long-term and short-term, as well as temporary campaigns ● Easy to learn, difficult to master
  27. 27. TrafficFlow in Italy Since 2015: ~ 30 installations 5 cities (Firenze, Prato, Empoli, Livorno, Castelfiorentino) ~ 94M passages!
  28. 28. TrafficFlow in London ● Hoxton Square (Unit9) 1k-2k veh/day 1.5k-3.5k ped/day ● Bethnal Green Road (NewSpeak House) 10k-12k veh/day (2x) ● Worship Street (OpenData Institute) 2k-3k veh/day (2x) 500-3k ped/day
  29. 29. A different flow pattern: London...
  30. 30. ...vs Florence
  31. 31. Pedestrians vs vehicles
  32. 32. OrganiCity Great opportunity for us to spread outside the Italian border Demonstration of ease of integration between TrafficFlow and other platforms Perfect completion for a participative approach at traffic-monitoring Potentially enabler of new services for the “smart city”
