摘要

Highway infrastructure projects always have negative impacts on the sustainable development objectives. However, theconstruction of these projects will not be stopped due to their importance for the fulfillment of the nations’ economic, socialand civilization development. Hence, it is necessary to find solutions for improving their performance toward the sustainabilityapproach. One of these solutions is to quantify the highway projects’ sustainability before starting in their execution.This will guide the decision-makers to adopt the suitable alternative and policy for the development of sustainable highwayinfrastructure. Previous studies did not adequately integrate the sustainable development dimensions in the construction ofhighway infrastructure projects, which represents an obstacle to the effective evaluation of highway projects’ sustainability.Addressing this issue, this research proposes an integrated index capable of appraising the sustainability performance ofhighway projects. The research data were collected from a questionnaire survey conducted with Egyptian experts with lengthyexperience in the construction of highway infrastructure projects. Fuzzy set theory and the analytic hierarchy process wereutilized to develop the composite highway sustainability index (CHSI). A case study was conducted to elucidate applicationof CHSI. The study offers the decision-makers an effective methodology to assess the sustainability of their highwayinfrastructure projects in early planning phases.
