Alternative Management of Traffic Accidents with Road Geometric Repair

Abstract

Severe accidents on the Gekbrong - Bangbayang road, Cianjur, very often occur and recur with the same pattern of events, which caused quite a lot of victims, in the form of property and lives. Handling of Field existing in n the form of making the ramp on the left side of the road, intended to halt vehicles that have failed brakes. This handling is certainly not rooted in the main problem, namely the steep geometric conditions of the road. Based on the data, the accident occurred on a vehicle that descended towards Cianjur. Failed brakes on vehicles that crashed on this road due to steep long descent. This geometric condition causes the driver - which is not normal through this section - to do continuous braking, which causes the brake lining to run out or the hydraulic brake system to be damaged, which in turn results in a severe accident. This situation can be avoided by improving the geometric conditions of the steep road, by changing the road alignment for vehicles going down towards Cianjur. Road alignment deflected in Gekbrong (KM 78 + 000) to the left, customized topographic data were made 2-3 bends, and end it merged back into the main line in Bangbayang (KM 74 + 000). While vehicles that ride towards Sukabumi continue to use existing roads with some geometric improvements, unless heavy vehicles are prepared for special lanes following the new road alignment.
