ABSTRACT

Bali, as one of Indonesia's premier tourist destinations, has seen a notable increase in visitors, particularly in South Denpasar, a hub for leisure activities. This rise in tourism has led to heightened traffic volumes, which challenge the area's road infrastructure, especially during the rainy season. South Denpasar is prone to frequent flooding and drainage overflow, which disrupt traffic flow and compromise road functionality. This study examines the impact of rainfall on traffic flow and road performance in South Denpasar. By analyzing traffic flow characteristics and correlating them with varying rainfall intensities, the study quantifies the relationship between rainfall and key road performance indicators. The findings reveal a strong correlation between rainfall intensity and declining road functionality. Additionally, the study introduces models that depict the effects of various rainfall intensities on road performance, offering a clear understanding of rainfall's impact in flood-prone areas. The results underscore the critical need for efficient drainage systems and strategic traffic management to mitigate the adverse effects of heavy rainfall. By adopting these practical measures, South Denpasar can enhance road resilience, reduce disruptions during rainy seasons, and maintain smooth traffic flow, ensuring a sustainable and reliable infrastructure for both residents and the growing number of tourists.
