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 are limited, for example to forecast the effects of: freight strategies, demand management approaches, price-based measures or walking and cycling policies.
Simplified models
Simplified models tend to produce mainly ‘indicative’ forecasts and do not replace the need for conventional transport models.
Simplified models may be needed when existing models have limitations in terms of appropriateness, sensitivity, flexibility, speed, cost or in the absence of other forms of modelling.
