  1. Wehad A limited number of permanent noise observation stations Source: www.lne.be 2009

  2. Wehad A limited number of air quality measurement sites with instantaneous (non-validated) interpolation Source: www.vmm.be 2009

  3. Wehad Typical patterns but limited source identification, limited alerting

  4. air (UFP) tiny noise reference noise IDEA brings More information at a cheaper price. total cost: 25 000 €

  5. IDEA brings Bottom up: alerting functionality and instant validation sensor error car truck train nature talking industry

  6. i Origin: Quality : medium Interpolation based on trafic data Closest measurement : 120 m Closest high-end : 890 m Time stamp : 1-2-2009 to 1-3-2009 ... LAden = 64 dBA PM10 = 34 g/m3 UFP = ... details origin origin details origin details origin IDEA brings Top down: interpolation and detailed querying

  7. IDEA brings Top down: interpolation and detailed querying Tracing sensor details Start: 6/3/2009 11:22 Location: //serv1.gent.be/tr23.xml Tracing sensor details Start: 6/3/2009 11:23 Location: //serv1.gent.be/tr24.xml

  8. 20 – 20000 Hz Noise floor: 22 dBA Long term weather proof -10dB€ 80 – 10000 Hz Noise floor: 30 dBA Wind protection Specific design 80 – 10000 Hz ? Noise floor: about 36 dBA ? Weather protection ? -10dB€ How? Just-accurate-enough sensors

  9. How? Moving sensors Vehicle equipped with (air pollution) sensors moves along the traffic stream and periodically forwards data via wireless link.

  10. How? Just-enough processing power Optimal use of distributed computing • Tiny CPU • Preprocess sensordata (average, filter) • Detect saliency in time • Make data available on the internet tiny

  11. How? Just-enough processing power Optimal use of distributed computing desktop • desktop CPU • Manage attention focussing and further analyses requests • Detect spatial saliency • Manage context • Manage decisions tiny

  12. How? Just-enough processing power Optimal use of distributed computing desktop grid tiny Grid computing is used for compute-intensive tasks

  13. How? Just-enough processing power Optimal use of distributed computing Connected via internet Wired or wireless

  14. How? Adding background information Intelligent extraction of knowledge Combining sensor information

  15. How? Adding background information Intelligent extraction of knowledge Adding source information Combining sensor information

  16. How? Adding background information Intelligent extraction of knowledge Physical transfer mechanism Adding source information Combining sensor information

  17. How? Adding background information Intelligent extraction of knowledge Calculated maps: noise & air quality Physical transfer mechanism Adding source information Combining sensor information
