Economics and appraisal

Print

Our aims are to ensure that decisions on transport policy are made in the light of the best possible advice on their impacts, and to ensure that investment in all modes of transport and their management meets the Department's policy objective to seek good value for money.

Our work includes forecasting growth in road traffic and other transport use, assessing the impacts of transport and other policies on these forecasts, developing and supporting appropriate methods for predicting the transport and economic impacts of road and other transport improvements, and setting the framework for assessing whether transport schemes are value for money.

Data sources

The Department has set up a number of data sources to provide information of assistance to those undertaking transport appraisal and modelling.

The National Transport Model

The Department has developed a National Transport Model (NTM) as an analytical and policy-testing tool, providing a systematic means of comparing the national consequences of alternative national, or widely-applied local, transport policies.

Software

We produce and support software for assessing whether road schemes provide value for money, publications providing guidance on how to predict the traffic impacts of road schemes, and traffic growth forecasts.

Research and development of guidance

The Department has a programme of research work on modelling, appraisal and evaluation. The aim of this work is to support the continuing development of the New Approach To Appraisal by improving our advice on transport modelling and economic appraisal.
