<![CDATA[This study is motivated by the increasing commuter mobility on the Tangerang–Jakarta corridor and the continuing competition between private motorcycles and the Commuter Line as daily transport modes. Objective: This study aims to analyze mode choice between private two-wheeled vehicles and the Commuter Line by comparing user perceptions and identifying service attributes that influence modal decisions. Method: This study employed a quantitative approach using a structured questionnaire distributed to 107 commuters. The data were analyzed using descriptive statistics, validity and reliability tests, the Mann–Whitney U test, and binary logistic regression. Findings: The results show significant differences in perceptions between motorcycle users and Commuter Line users across all service attributes, including security, safety, orderliness, smoothness, satisfaction, comfort, travel time, intermodal integration, and accessibility. However, the logistic regression results indicate that only travel security, safety, and orderliness significantly influence mode choice. Implication: These findings imply that modal shift policies should prioritize risk reduction, operational safety, and service orderliness to strengthen the attractiveness of rail-based public transport. Originality: The originality of this study lies in its direct comparison between motorcycle users and Commuter Line users on the Tangerang–Jakarta corridor by combining perception difference analysis and mode choice modeling.]]>
