Assessing transport requirements
A transport model is a mathematical representation of all or part of a transport system. It is used to evaluate existing conditions and to project future effects and needs. An increasing emphasis on interaction between transport modes and travel choices and the need for a transparent approach to scheme appraisal and selection has made transport modelling an integral part of the appraisal process.
Models can be as simple as a diagram of predicted traffic flows but more often involve the use of specialised computer programs to assess large geographic areas, complex interactions or a range of demand responses
We have continued to develop our transport modelling capabilities and can offer comprehensive modelling services, including wide-area network assignment modelling and micro-simulation techniques. We have extensive experience in developing models using SATURN, VISUM, DIADEM, Paramics, AIMSUN and VISSIM software. The options we use for transport modelling include:
