Ministry of Finance and Economic Planning Republic of Ghana Integrated Transport Plan for Ghana Volume 8: Project Evaluation Final Version June 2010 Financed by the 9th European Development Fund Service Contract N° 9 ACP GH019 In association with Egis Bceom International Executive Summary This report presents the process and the results of the project evaluation process used in the Integrated Transport Plan. The methodology for project evaluation has been described in the Multi-criteria Evaluation Manual. The evaluation process compares the “with” and the “without” project situations in order to estimate the benefits from the project. The main economic savings accounted for are savings in travel time and savings in travel costs. Comparing these savings with the project cost is the basis of the economic analysis. In addition to the economic evaluation, a number of social and environmental criteria have been accounted for; these include Environmental Impact, Social Effects, Strategic Access, Inter & Intra-Modal Integration and Local Access. Several projects have been evaluated on the basis of capacity requirements and surface conditions in order to satisfy the future demand for transport. Annex 3 summarizes the evaluation results. The projects identified as economically viable and with their optimal year for putting in operations during this plan period are: Final NPV / Optmum Section Lenght Main Works Multicriteria Disc.Inv.

A multi-dimensional approach The evaluation of the projects is undertaken using a multi-criteria analysis approach integrating economic, social, environmental aspects, strategic access, inter and intra modal integration, and local access aspects: Economic viability . This criterion takes into account the economic viability of the projects and should use indicators based on a cost-benefit approach. Environmental effects . This criterion takes into account the possible negative environmental impacts of the projects. The type of impact may vary from one mode to another. For instance, port projects have an impact on marine ecosystems that has not to be considered for other modes. Social effects . In particular, this criterion takes into account the effects of the project on poverty alleviation. This effect is mainly related to the increasing accessibility to job opportunity and health/education services given to poor people; however, it also takes into account negative impacts such as resettlement. Strategic access . This criterion takes into account the capability of the projects to improve the economic and physical access to strategic transport routes for goods and passengers. Inter and intra modal integration . This criterion is related to interchange facilities required as part of transport infrastructure projects. Local access . This criterion regards local access aspects including integration of NMT. The economic analysis of the projects takes into account, explicitly or implicitly, a number of parameters such as: the population and the type and level of economic activities
