Abstract:
Sustainability concerns on Tanzania’s road transport infrastructure are mounting, calling
for research in this area. This study examines technology’s mediating role in
sustainability. It explores links among Economic (ECD), Environmental (ED), Social
(SD), Technological (TD) dimensions, and Sustainable Road Transport Infrastructure
(SRTI). Using surveys, 252 participants were involved from Dar es Salaam, Mwanza, and
Arusha. Questionnaire data underwent Partial Least Squares-Structural Equation
Modeling analysis with Smart PLS 4. Results reveal technology positively mediates
relationships between economic, environmental, social dimensions, and sustainable road
transport infrastructure. Findings emphasize technology's crucial role and the potential of
technological advancements to enhance sustainability. The study recommends that road
transport infrastructure development agencies prioritize the integration of sustainability
factors, particularly technology in projects. This research contributes by highlighting
technology's mediation in Tanzanian road transport infrastructure sustainability and the
importance of leveraging technological advancements to promote sustainability in road
transport infrastructures.
