Definition – Transport modelling is a mathematical representation of transport demand and resulting trips, based upon economic, municipal, household and transport data and projections, and using formalised behaviour hypotheses and assumptions. Traffic models are used to analyse and forecast the traffic situation and to predict the outcomes of transport strategies. This can include the identification of potential congestion “hotspots” within the transport system.
Relevance to SUMP – Practitioners are advised to use both modelling and qualitative analysis to support scenario appraisal and measure selection. In doing so, however, transport modellers need to be sure that input parameters are appropriately set in the model to ensure the accurate measurement of all modes – including cyclists and pedestrians.
