Road Infrastructure Deficiency and Road Safety Audit at Black Spot Area in Rural Road

Abstract

Abstract One of the factors that caused traffic accidents is road infrastructure. Strategies to minimize the road deficiency infrastructure is implementation of the forgiving road, self-explaining road, and self-regulating road. The purpose of this study was analyzing the deficiency of road infrastructure and implementing the road safety audit at black spot areas in rural areas. Study location in Bojongsari Street, Purbalingga. Parameters that are analyzed in deficiency of road infrastructure include the road geometric condition, road pavement performance, and road equipment facilities. Parameters that analyzed in road geometric condition, namely stopping and passing sight distance, lane width of road, and road shoulder width. The results of this study show that the highest passing and stopping sight distance of all vehicles was motorcycles at 304.48 m and 64.67 m. The road pavement performance based on pavement condition index for the longitudinal/transverse cracking conditions is 94 and for the lane or shoulder drop-off condition is 77. Recommendations given based on road safety audit results for road geometric is to improve the road shoulder, for pavement condition improves shoulder drop-off and longitudinal/transverse cracking. For the road equipment facilities are to install the maximum speed limit sign of 40 km/h and install the warning sign.
