Abstract: The rapid development of road infrastructure today presents significant challenges in ensuring road safety. The National Road III section from Kabat to the Banyuwangi City Boundary has shown a concerning trend in traffic accidents, highlighting the need to identify accident locations. This study employed secondary data obtained from the Banyuwangi Police traffic unit accident reports. The research analysis was conducted in two phases. First, the Z-score method was utilized to identify accident road segments through statistical evaluation. Subsequently, Hotspot Analysis (Getis-Ord Gi*) integrated with Geographic Information System (GIS) was applied to map and verify the spatial clustering of accidents. Both methods consistently identified two critical segments out of 25 road sections (each 200 meters in length). These were located at STA 5+200 – 5+400 with a 95% risk level and STA 8+400 – 8+600 with a 90% risk level, while the remaining segments did not show statistically significant clustering of accidents. The consistency of results across both methods strengthens the reliability of the findings, underscoring the importance of targeted safety interventions and accident mitigation strategies in these high-risk zones.
