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.
