Modelling

Transport Model GraphicModels and analytical techniques are required, to:

  • Forecast future conditions.
  • Test future alternatives and options
  • Demonstrate value for money

Conventional transport models

Conventional (or ‘classical’ four-stage) transport models are the dominant form of model used for transport planning purposes.

Conventional transport models represent a very considerable and indispensable resource to the sector, in terms of the capture and analysis of detailed information regarding current trip movement patterns and traffic volumes.  

For some test purposes, conventional transport models (even if they are multi-modal) are quite limited, for example when forecasting the effects of freight strategies, demand management approaches, price-based measures or walking and cycling policies.  As a result other techniques are often needed to supplement conventional transport models.


Simplified models

Simplified models tend to produce mainly ‘indicative’ forecasts and are additional to rather than a replacement for conventional transport models.

Simplified models may be needed when existing models have limitations in terms of appropriateness, sensitivity, flexibility, speed, cost or where there is an absence of conventional transport models.
