- Description: Abstract: t Purpose of this paper Transportation infrastructure contributes significantly to any economy. However, the long-lasting nature of such projects is threatened if sustainability elements are not taken cognizance of during the planning and operation stages of the projects. The objective of the current study is to validate a structure of transportation project sustainability measures to evaluate projects and ensure continual delivery of intended benefits in the long run. Design Empirical data were collected using a field questionnaire survey developed from literature review and a preliminary qualitative inquiry. A total of 132 built environment professionals were included based on purposeful and snowball sampling techniques. A model-generating confirmatory factor analysis was undertaken to validate underlying structures of sustainability measures. Findings The findings validated that a four-factor structure, with eleven variables, could adequately measure transportation infrastructure project sustainability (PS). The CFA structure achieved construct, convergent and discriminant validity, with fewer variables than theorised and established in the exploratory factor analysis. Value The validated four-factor structure is envisaged to be beneficial to transportation infrastructure project stakeholders in better decision-making with regard to selecting worthwhile projects as well as monitor operational projects with the aim of delivering long-term benefits to generations of users.

- Description: Abstract: Transportation infrastructure contributes to the development of an economy. However, the performance of such infrastructure is hampered if sustainability elements are not considered at the initiation/conception and operation stages of the projects. The study aimed to validate a structure of transportation project sustainability measures to evaluate projects and ensure continual delivery of intended benefits in the long run. Empirical data were collected using a field questionnaire survey developed from the literature review and a preliminary qualitative inquiry. A total of 132 built environment professionals were included based on purposeful and snowball sampling techniques. A model-generating confirmatory factor analysis was undertaken to validate underlying structures of sustainability measures established from a...
