SCOOT

SCOOT - example

SCOOT and The iC Continuous Data Capture: –Flow –Delay –Stops –Congestion –Signal Timings –Detailed Flow Measures –Queue Length Control

ITS Mobile AQ Van

Contd… Monitors: –CO –NO/NO2/NOx –O3 –SO2 –PM 10 or 2.5 –Met ( Wind Speed & Direction, Temp, RH, Solar radiation ) –Location GPS Internal Battery 12 hrs Lamp post stand etc

Streetboxes – up to 10

Contd… Monitor CO some with NO 2 Electrochemical Cell Sensors CO - Excellent performance –Correlation AURN Type sensor –Repeatability NO 2 - Poor performance Time synchronisation from laptop Internal power supply & data-logging Radio modems & Direct RS232 Installation straight-forward

Particle Monitors TSI 3007 CPC –Ultra-fine particle count DIRECT GRIMM –Light scatter –Particle COUNT dist. or converted MASS dist.

Meteorology Measurement of velocity field at up to 7 spatial locations 3-component sonic anemometers AC power supplied by lampposts Data transmitted by radio modem to nearby receiving base station With 7 anemometers max. sampling frequency of 10 Hz Supply anemometers, radio modems, base station PC & support Radio modem

Will require on-site testing of signal strength and radio channel interference
