2 We had A limited number of permanent noise observation stations Source: 2009

3 Source: We had A limited number of air quality measurement sites with instantaneous (non-validated) interpolation

4 We had Typical patterns but limited source identification, limited alerting

5 IDEA brings More information at a cheaper price. air (UFP) tiny noise reference noise total cost: total cost:

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

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

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

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

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

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

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

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

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

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

17 How? Adding background information Intelligent extraction of knowledge Combining sensor information Adding source information Physicaltransfermechanism

18 How? Adding background information Intelligent extraction of knowledge Combining sensor information Adding source information Physicaltransfermechanism Calculated maps: noise & air quality

19 How? Adding background information Intelligent extraction of knowledge Combining sensor information Adding source information Physicaltransfermechanism Calculated maps: noise & air quality Moving sensor information
