The deficiency of road infrastructure is a reduction or decrease in the function of road infrastructure resulting in inefficient functioning of road infrastructure. This can trigger potential traffic accidents. Traffic accident is one of the serious problems in road traffic. Road crash are not only caused by the condition of the vehicle and driver, but also due to many factors, including road design (horizontal alignments and vertical alignments), stop sight distance, road pavement condition, completeness of traffic signs or directions, and weather. The aim of this research was to analysis the road safety audit of infrastructure deficiency at black spot area in arterial road at Purbalingga. The study location was in Mayjend. Sungkono Street, Blater, Kalimanah, Purbalingga, Central Java, Indonesia. Three parameters that analyzed in road safety audit i.e.: condition of road geometric, condition of road pavement, and harmonization of road equipment facilities. The result of the study shows that some of road infrastructures must be repaired to reduce the potential traffic accident. Road geometric aspect involves the preceding sight distance and shoulder width. Aspect of road pavement condition involve lane or shoulder drop off. Harmonization of road equipment aspect involves speed limit sign (50 km/h and 40 km/h), warning sign along black spot location.
