Abstract

This study proposes to evaluate and identify the significant factors affecting road users’ satisfaction level. This study
mainly focuses on investigating the related factors that may contribute to satisfaction level of all road users on Motorway
Route 7. The questionnaires are developed and separated into three main sections, which are respondent profiles, measurement of the level of satisfaction toward each indicator, and the overall satisfaction of travelers on the Motorway Route 7.
Several statistical techniques are proposed, such as exploratory factor analysis and multiple regression. Moreover, descriptive correlation analysis is conducted to show that the dependent variables contribute to the independent variable.
The study has shown that the highway conditions are the most significant factor affecting road users’ satisfaction. The
completed result of this study is expected to serve as a guideline for highway authorities to improve their service ability level
along Motorway Route 7.
