Background:
Using the technology acceptance model (TAM) as its theoretical foundation, this study intends to explore the use of Travelling Beam Device devices in road engineering in Taiwan and offer suggestions based on its findings to encourage the willingness in the industry to use the devices more and, as a result, improve the road pavement smoothness in Taiwan.

Material and methods:
The samples in this study were the road engineering workers in Taiwan. Totally 107 valid questionnaires were returned. The questionnaire results were analyzed using methods of descriptive statistics, confirmatory factory analysis and structural equation modeling.

Results:
Study results shown that more training/support and perceived ease of use can lead to more willingness to use travelling beam devices and consequentially helps to improve the pavement smoothness.

Conclusions:
SEM analysis results also indicate training/support, perceived ease of use and attitude will give users positive attitude toward the use of travelling beam devices.
