Kirklees demonstrate how Dynniq is “lifting the lid” on air quality management

Kirklees Council and ITS (UK) member Dynniq UK have won the award for best paper at this year’s JCT Traffic Signals Symposium.

With Air Quality gradually worsening and no viable solutions, Dynniq seek to solve the problem by taking a different seat in Air Quality Management (AQM), having recognised that Air Quality is simply a symptom and not the cause. Typically local authorities are using Air Quality monitors to influence signals, which is simply treating the symptoms.

The company says it uses a bespoke software solution, Virtual Emissions Monitor (VEM), to accurately identify causes through the measurement of vehicle emissions without the need of additional infrastructure. Kirklees County Council adopted the system to determine the effect of Adaptive Signal Control on emissions and the economic impact.

Dave Caborn, UTC Manager at Kirklees Council, who delivered the paper at the JCT Symposium commented, “Kirklees Council are proactively looking to improve the lives and health of its citizens by providing reliable journey times and improving Air Quality. The VEM trial proves that this can be achieved and although it is not the final solution it now gives us a cost effective means of moving forward to find that solution and achieving our aims.”

The initial project work showed a 31% reduction in emissions when SCOOT was used over fixed time signals. The real benefit of having the VEM however, is that it is able to continually capture and report the Virtual Emissions Data, meaning any subsequent changes made, or fine tuning of the control strategies or SCOOT plans can be immediately observed and verified.
