Paramics Discovery used to assess Low Emissions Zones in Aberdeen
Many cities around the UK are exploring the introduction of Low Emissions Zones (LEZs), to reduce carbon emissions and improve air quality. Paramics Discovery is an ideal tool for assessing road network options associated with the introduction of LEZs.
SYSTRA Ltd was commissioned by Aberdeen City Council in August 2019 for professional services to develop a Paramics Discovery microsimulation model of Aberdeen City Centre. The Paramics Discovery model was created to assess options associated with the development of an LEZ in Aberdeen.
The Interim NLEF (National Low Emissions Framework) Stage 2 Appraisal recommended four different LEZ boundary options be assessed using the Aberdeen City Paramics Discovery model. Key performance indicators were collected from the model to establish a preferred option(s). These elements were:
Network Demand Level & Congestion Areas
Impact through Air Quality Exceedance Locations
Alignment with Network Hierarchy
Car Park Accessibility Impact
Impact to residential properties within LEZ area
An example of traffic flow analysis on the road network as part of the LEZ assessment in Aberdeen
An example of road network conditions in Paramics Discovery as part of the LEZ assessment in Aberdeen
Operational performance and output statistics from Paramics Discovery were used in tandem with Air Quality Dispersion Modelling and Strategic Traffic Modelling analysis to establish a preferred option and feed into the overall assessment.
