Abstract:

This paper presents a horizontal approach to ranking aggregation in a methodology of multiple-level, multiple criteria assessment of urban transportation projects (UTPs). The objective of this research was to advance an alternative approach to ranking aggregation based in the first place on an original calculation/aggregation formula to obtain a hierarchy of UTPs in terms of their global utility obtained within the predefined UTP classes based on their sub-utilities (substantive, sectoral, strategic); and second, on an original normalizing aggregation formula for global utilities of relevant UTPs from predefined classes to arrive at a hierarchy of UTPs in the final ranking according to the global utility of all UTPs in the entire population (regardless of their respective transport project classes). Horizontal ranking aggregation in the methodology of multiple-level, multiple criteria assessment of UTPs is carried out at only one level of the methodology, namely Level V.

This paper also evaluates the proposed horizontal ranking aggregation approach in the aforementioned methodology. This assessment was carried out by comparing the obtained final ranking according to the horizontal ranking aggregation approach with the final ranking of the same UTPs obtained through “vertical ranking aggregation”.
