- Description: Abstract: Sustainable transportation is vital since its impact traverses generations. The concept of sustainable transportation is known to account for incorporation of various elements including environmental, economic, social and institutional factors. The current study employed exploratory factor analytic technique using maximum likelihood factoring to identify critical indicators for assessing transportation infrastructure projects in South Africa. Using purposive and snowball sampling, a questionnaire was distributed via email, google forms and by hand, to project managers, directors, construction managers, planners and feasibility study consultants involved in transportation projects at different stages, in the nine provinces of South Africa. Empirical data amassed from 132 responses, were analysed using SPSS version 25 software.s Descriptive analyses were used for preliminary analyses. Inferential statistics was conducted using exploratory factor analysis, to output common factors and the minimum number of variables that were related to each construct. Findings revealed that a four-factor structure including infrastructure condition and impacts, user acceptability, financial management and safety and security, can adequately measure transportation infrastructure project sustainability. By establishing critical indicators for assessing transportation projects, the study provides relevant evidence to develop strategies to ensure that such investments bring lasting and desirable impacts in the long run. The study was conducted in South Africa and may not be generalisable to other geographical regions, which may have differing priorities with regard to sustainable performance of transport infrastructure. Further studies are on-going to validate the four-factor structure using confirmatory factor analytical techniques.

- 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...

- 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.
