Using the technology acceptance model (TAM) as its theoretical foundation, this study intends to explore the use of Travelling Beam devices in road engineerings in Taiwan and offer suggestions based on its findings to encourage industry willingness for device deployment resulting in improving road pavement smoothness in Taiwan. The study subjects were pavement smoothness device operators in Taiwan. A total of 107 valid questionnaires were returned. The questionnaire results were analyzed using descriptive statistics, confirmatory factor analysis and structural equation modeling. Study results show that more training/support and perceived ease of use can lead to more willingness to use travelling beam devices and consequentially help improve pavement smoothness. Structural equation modeling (SEM) analysis results also indicate training/support, perceived ease of use and attitude will give users' positive attitudes towards use of travelling beam devices.
