A Case Study about Developing Harmonised European Approaches for Transport Costing and Project Assessment
Summary: Case studies on four TEN-T projects were selected, the HEATCO methodology applied and compared with the national methodologies and outputs. The outcome can be judged as positive, since the HEATCO methodology was successfully applied in all four cases. No major difficulties were reported on scientific, methodological or technical problems related to the application of HEATCO. A number of sensitivity tests were conducted. The research revealed that the social discount rate and the value of travel time savings VTTS are of particular importance for the outcome of the appraisals and thus sensitivity tests are highly recommended. Sensitivity tests for climate change and noise revealed only minor changes (<5%) of overall benefits.
Objectives: Transport investments on the Trans European Network (TEN) level are usually of large scale and thus require thorough appraisals. The methodology for these investments needs to be consistent, reflect the state of the art and be feasible in its application. HEATCO had the task to develop a harmonised European approach towards transport appraisals that fulfils these requirements. The recommendations were developed and compiled in Deliverable.
