This paper will discuss transport modelling, with a focus on accessibility modelling, and how this can be used to inform scheme appraisal, using a major London transport scheme Crossrail as an example. The appraisal framework for the Crossrail project follows the UK government guidance, which focuses on the five overarching policy objectives of: economy, safety, environment, accessibility; and integration. The appraisal framework considers additional issues, included in the guidance, relating to distribution and equity, affordability and financial sustainability, and practicality and public acceptability. The accessibility modelling for Crossrail combined a strategic public transport model of London and a Geographical Information System (GIS) package to allow the detailed modelling of journey times to and from particular areas such as town centres, employment centres and regeneration areas. This paper goes on to describe some examples of the communication of model outputs and the linkages to appraisal frameworks.
