Details

Gross domestic product (GDP) is a measure of the size of an economy and of the volume of goods produced at a certain price level within the economy.

Transport projects can impact GDP by increasing the productivity of the economy.

This research considers whether a transport analysis guidance (TAG) cost benefit analysis can be used to forecast the GDP impact of a transport project.

TAG provides information on the role of transport modelling and appraisal and how the transport appraisal process supports the development of investment decisions to support a business case.

Peak Economics and ECPC conducted this report on behalf of Department for Transport.
