CBA Results of CPK Railway Program with Modulated Methodologies

Cost–benefit analysis (CBA) lacks the formal nature often associated with financial analysis. In Europe, CBA typically adheres to a predefined methodology set forth by the European Commission, specifically for the purpose of applying for EU funding. However, when used internally by project promoters or for national transport policy purposes, the CBA scope may extend beyond the Commission’s recommendations. This is particularly true since additional effects can be calculated using existing methodologies. Using an example of one of the HS rail projects developed by CPK in Poland, based on the standardized CPK CBA Model, multiple simulations of the CBA results were carried out, incorporating various assumptions, methodologies, and a range of effects considered in the analysis. The simulations are of different nature than a standardised sensitivity analysis. Conclusion had been drafted as to the observed changes in the CBA results.
