This study analyzes the determinants of road freight companies' adoption intention regarding the electric road systems (e-roads) on Swedish motorways. A research model was developed based on the technology adoption literature and Technology-Organization-Environment (TOE) framework. Survey data were gathered from 160 Swedish road freight companies, and structural equation modeling was performed to test the model empirically. The results reveal relative advantage, a technology characteristic, as the main determinant of road freight companies' intention to adopt electric road systems. The study contributes to the TOE framework by reporting on the indirect effects of technological and organizational determinants on organizational intention to adopt technologies. © 2023 World Scientific Publishing Company.
