Abstract
Transport infrastructure meets the demands for people and cargo delivery by providing access to
working, shopping and travelling and improving the quality of life of citizens. Road infrastructure
needs to be sustained for eons after its development. However, there is no consensus on the criteria
upon which the operational performance of road infrastructure projects is assessed. This paper
aims to identify all potential criteria for assessing road projects in operation. A desk study was
conducted using relevant journal and conference papers obtained from databases including ASCE
Library, Science Direct and Ebscohost. Thematic analysis was used to identify emerging themes
from extant literature. The themes were tabulated and ranked based on their frequency of
occurrence to determine the most important criteria for measuring the performance of road projects
in operation. Findings indicate that institutional productivity and effectiveness, operational
efficiency, health and safety, mobility, environmental element, public acceptability, asset value,
legal and technical factors can be used to assess the performance of road projects. The study
provides vital information which would be beneficial to project managers, and indeed investors,
in assessing and projecting sustainable performance of road projects in operation.
