Analisis dampak lalu lintas pada pembangunan gedung pusat onkologi terpadu di rumah sakit pusat umum Klaten

The development of the Integrated Oncology Center at the Central General Hospital (RSUP) Klaten is anticipated to generate significant traffic demand due to increased visits by patients, accompanying family members, medical staff, and operational vehicles. This study evaluates the traffic impact of this development on the performance of the Solo–Yogyakarta road segment by analyzing traffic volume characteristics, roadway capacity, and Level of Service (LOS) in accordance with the Indonesian Road Capacity Guidelines (PKJI 2023). Primary data were obtained through traffic surveys conducted on Sunday and Monday across three peak observation periods: morning, midday, and afternoon. Traffic volumes were converted into Passenger Car Units (PCU/hour) utilizing PKJI 2023 equivalency factors. Analysis reveals an existing roadway capacity of 4,224 PCU/hour. Under current conditions, the Degree of Saturation (DS) ranges from 0.37 to 0.41 for both directions, corresponding to LOS B. Upon full operation of the oncology facility, DS values are projected to rise to 0.41–0.46, maintaining LOS B status. Furthermore, a five-year traffic projection—assuming an annual growth rate of 4.8%—indicates DS values ranging from 0.52 to 0.58, equivalent to LOS C. These findings demonstrate a gradual decline in roadway performance; however, the segment remains capable of accommodating the projected traffic demand. Consequently, development is deemed feasible from a traffic engineering perspective. Nevertheless, the implementation of strategic traffic management measures and gradual capacity enhancements is recommended to sustain acceptable roadway performance and ensure long-term traffic safety.
