Paramics Discovery used to test Air Quality Action Plan in Crieff

SYSTRA has successfully completed an upgrade of the Crieff microsimulation traffic model, originally developed in 2012 using S-Paramics, to the latest version of the software - Paramics Discovery.

The model covers the whole of the town and its approaches and will be used to undertake scenario testing to inform air quality modelling work around the local authority’s proposals for an Air Quality Action Plan (AQAP).

Located on a hillside, Crieff includes a number of roads with steep gradients. Consequently, the road network description includes node heights so that the gradients are correctly represented, thereby influencing vehicle behaviour in terms of acceleration, deceleration and braking.

The model has been developed to look at options to improve air quality along Crieff High Street, which forms part of the A85 trunk road from Perth to Lochearnhead. Options to be looked at include modelling the effects of removing the on street parking, both legal and illegal, and the introduction of traffic signals at key junctions to assess the resultant changes in air quality. The model will also be used to test the proposed Local Development Plan allocations in the area.
