This document presents the economic case for the ‘Road investment strategy’ (RIS). It covers:

  • major schemes
  • capital renewals
  • network management and the traffic officer service
  • ring-fenced budgets

Individual scheme modelling is presented and major schemes as a whole are also modeled using the National Transport Model. It considers monetised and non-monetised costs and benefits, benefit cost ratios and sensitivities in the estimates. It demonstrates a strong case for the RIS investment package.

The RIS was announced on 1 December 2014. It sets out how £15.2 billion of capital funding on the strategic road network will be allocated between 2015 and 2021.
