SAIT. Definition of the evaluation system for transport infrastructure investments of the Catalan Government

Client: Departament de Territori i Sostenibilitat, Generalitat de Catalunya
Dates: 2014-2016


The main objective of this project is to establish a new assessment system for transport infrastructures based on the Cost-Benefit Analysis (CBA) methodology. This methodology will be the common assessment system to determine which of the possible investments in road and rail infrastructure will obtain greater benefits, therefore to ensure the proper use of public resources.

The project provides an analytical tool to be used to appraise an investment decision in order to assess the welfare change attributable to it and, in so doing, the contribution to Catalan Government objectives. The purpose of CBA is to facilitate a more efficient allocation of resources, demonstrating the convenience for society of a particular intervention rather than possible alternatives.

The CENIT developed the tools and the guidelines to be used by all the stakeholders involved in the transport investments.

CENIT provided the following services:

  • Review of the actual CBA methodologies and European manuals.
  • Critical analyses of difficulties and important aspects to take into account in the evaluation systems.
  • Set of criteria for the selection of the agents and impacts to be considered in the evaluation of transport infrastructure inversions.
  • Definition of the guidelines to support policy-makers, with all the process and aspects of the CBA.
  • Implementation of the methodology in different case studies.
  • A computer-based tool to implement the methodology according to the standardised process and data, and a support guideline.
  • Recommendations offered for an improvement of data and demand models.
  • Definition of the next stages of the manual.
