Fatality level can be reduced with the deficiency safety program as an effort in handling the accident thatoccurred on the road. This study aims to investigate the influence of the road infrastructure condition and toassess the best solution to minimize the probability of the accident. The parameter used to determine thelocation of the study was based on AEK's value, fatality's level, and accident frequency. This study wascarried out in the black spot at Yogyakarta – Wonosari road, that were: (1) Bunder (KM 10+944 m); (2)Pekerjaan Umumtat (KM 7+864 m); and (3) Patuk (KM 0+874 m). This analysis was perfomed using the IKJwith measuring design deviation (geometric and road's facilities harmonization) toward technical standard.Infrastructure improvements should be conducted to conform components based on the risk analysis.Handling priority of deficiency road infrastructure in the black spot should be based on: (1) traffic handling;(2) harmonization of fringe and mark; and (3) arrangement of road‘s facilities
