Abstract

This study presents a systematic review of recent literature that explores the relationship between road capacity and level of service (LOS), two critical components in transportation engineering and urban planning. As traffic volumes continue to grow in urban environments, understanding how road capacity impacts service quality is essential for improving mobility, reducing congestion, and planning sustainable transportation systems. The review synthesizes findings from multiple peer-reviewed sources, focusing on key methodologies, variables, and evaluation criteria used to assess capacity and LOS in different contexts. In addition to traditional analytical frameworks, this study incorporates a bibliometric analysis using VOSviewer to visualize keyword connections and research trends. The results reveal that evaluation methods, road geometry, and strategic design are dominant themes in literature, while gaps remain in studies integrating real-time data and behavioral factors. This research contributes to the field by mapping current knowledge, identifying emerging research directions, and offering insights for future transportation policy and infrastructure development efforts.
