Supplementary transport appraisal guidance discussing the development of bespoke mode choice models as part of the transport demand model.
Bespoke modelling, while not generally used and costly, may be necessary:
- for appraisal of new modes or new characteristics
- for appraisal of schemes in areas where traveller behaviour may be substantially different from national norms or values from other existing models
- when the transfer of an entire model system from another area could be considered, only if model transfer is appropriate
The transport appraisal guidance ‘M2 variable demand modelling’ supplies cases where it is judged that a bespoke mode choice model was most appropriate approach.
