Abstract

The deficiency of road infrastructure reduces or decreases its efficiency, thereby, resulting in inadequate functioning, capable of triggering traffic accidents. This is also one of the major causes of traffic accident on roads. Interaction between human errors and road infrastructure cause road traffic accident 34%. Road accidents are not only caused by the condition of vehicle and driver, but also due to many factors, including its design (horizontal and vertical alignments), preceding and stop sight distance, pavement conditions, and completeness of road equipment facilities. The aim of this research was analyzing road infrastructure deficiency at black spot area to increased road safety. The study location was in Brobot Street, Bojongsari, Purbalingga, Central Java, Indonesia. Three parameters that analyzed in road infrastructure deficiency i.e.: condition of road geometric, condition of road pavement, and harmonization of road equipment facilities. The result showed that some road infrastructures must be repaired to reduce traffic accidents. Road geometric aspect involves the shoulder width, (improve the shoulder to 1.5 m wide), while its pavement condition involve lane or shoulder drop off. To harmonize these inconsistencies equipment such as install maximum speed limit sign (40 km/h), warning sign along black spot location should be perfectly located along these roads and install traffic sign.
