Sustainable transportation: an overview, framework and further research directions

In our study we have attempted to develop a theoretical framework for sustainable transportation based on synthesis of exhaustive review of extant literature. To test the framework statistically, a structured questionnaire was designed. Measures for the questionnaire were adopted from extant literature and to operationalise the constructs further, the questionnaire was to be pretested. Adding to this, the validity of the constructs was examined using confirmatory factor analysis followed by partial least square – structural equation modelling to test research hypotheses. The statistical analyses suggest that model exceed the threshold limit for goodness of fit test. Except government policy, all five research hypotheses are accepted. The present study is a unique contribution in terms of its theoretical implications and practical use. Finally, our research findings were concluded and further research directions were outlined.
