Abstract
Sustainability assessment of infrastructure projects aims at supporting the selection or maintenance of the best investment option among alternatives. However, there is no consensus on the indicators of sustainability performance of transportation projects especially during the planning stage of projects. The current study therefore investigated the underlying structure and thus minimum number of factors that can be used to assess transportation infrastructure sustainability. Using empirical data collected from a field questionnaire survey among 132 built environment professionals in South Africa, an exploratory factor analysis (EFA) was conducted to identify the underlying structure of theorised transportation project sustainability measures. Findings revealed a four-factor structure comprising infrastructure condition and impacts, user acceptability, financial management factors, as well as safety and security. The validity and reliability of these common factors were demonstrated. The four-factor solution is envisaged to be useful in ex-ante and ex-post evaluation of transportation infrastructure projects in order to ensure that such proposed and/or existing projects deliver intended objectives and benefits in the long run.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
