Traffic congestion at intersections and urban corridors is strongly influenced by road capacity, side frictions, and driver behavior. This study analyzes the traffic performance of Gajayana Street, Malang City, by evaluating traffic volume, road geometry, side frictions, travel speed, capacity, degree of saturation (DS), and Level of Service (LOS). Data were collected through field surveys and analyzed using the Indonesian Road Capacity Guidelines (PKJI 2023).
The results show that the highest traffic volume occurs during peak hours between 16:15–17:15 WIB, reaching 2,030 PCU/hour. Side friction analysis indicated a weighted frequency of 146.9 events/hour, categorized as low, but still significant during peak demand. The average travel speed of light vehicles was 35.7 km/h. Under a two-way configuration, the DS reached 1.0, resulting in LOS F (unstable flow, heavy congestion). In contrast, the one-way configuration produced a DS of 0.68, corresponding to LOS B (stable flow).
These findings suggest that traffic performance on Gajayana Street can be significantly improved through operational schemes such as one-way management, alongside measures to minimize side frictions and enhance driver compliance. The study highlights the importance of integrating infrastructure planning, traffic management, and behavioral interventions to achieve more efficient and sustainable urban mobility
