AQMesh used in Transport Scotland’s Collaborative Sensor Rotation Programme
Transport Scotland recently piloted the installation of low cost air quality sensors at several locations near the trunk road network.
AQMesh pods were deployed at these various roadside locations to monitor the levels of pollutants. At the same time, traffic data was collected to allow comparison between traffic volume, speed and classification.
Analysing the traffic data indicated good correlation in certain circumstances, with lower speeds coinciding with higher readings in some pollutants. When cross-referenced with AQMesh data, it was found that the air pollutants linked with the most harmful traffic emissions are NO2 and PM2.5.
The full findings of the Collaborative Sensor Rotation Programme (CSRP) are available on the Transport Scotland website.
