Transport appraisal and strategic modelling (TASM) research reports

Analysis, appraisal, evaluation, modelling, and research which has been carried out to inform transport decisions and policies.

To ensure that transport systems are effective, transport decisions and policies made by government and the transport sector, are based on:

  • economic and statistical analysis
  • appraisal
  • evaluation
  • modelling
  • research

To provide the best evidence base for planning policies and schemes, mathematical models, guidelines and software are used by DfT to analyse complex transport patterns.

These reports provide details of research which has been carried out to inform transport decision making.
