60 My AQMA on the public road is likely to remain, and is largely attributable to road transport. What input can I expect from Roads Service in terms of Review and Assessment? [Northern Ireland]AQMA Road Road motorway roads service highways 21/11/2016
62 Is the example in Box 7.2 of LAQM.TG(09) correct?Road Modelling Pollutant 7.2 NOx NO2 Nitrogen Reduction tg09 technical guidance 21/11/2016
63 Measurements of nitrogen dioxide have been made over the last few years at the kerbside using diffusion tubes. Is there any way the results can be used to assess concentrations at the facade of nearby residential properties, to allow comparison with the annual mean objective?Monitoring Pollutant Road Fall Distance nox no2 nitrogen kerb road diffusion tube 21/11/2016

134Box 2.3 of LAQM.TG(09): how to predict nitrogen dioxide concentrations at different distances from roads. The calculation specifies that distances should be measured from the kerb of a road. I am interested in a road along which cars are parked most of the time, so moving traffic does not use the nearside lane. Should I measure my distance to the kerb or to the edge of the nearest trafficked lane?road kerbside distance from kerb fall-off monitoring diffusion21/11/2016
