The Implementation of Centrifugal Force in the Geometric Design of Road for Safety Driving Convenience on the Cisarua sta.0+050-1+450

The road of Cisarua - Ngamprah has winding conditions and can result in accidents from a geometric perspective. Some of the reasons are because the radius, visibility, and pavement widening at bends have inappropriate road slopes. This research aims implementation of centrifugal force in the geometric design of road for safety driving Conveniencet at the Cisarua sta. 0+050 -1+450. This research method uses evaluative and quantitative methods. Data collection is carried out by observing road locations and the agencies responsible for completing geometric traffic data. Data analysis was carried out on centrifugal strength calculation, the highway gradient, arch sharpness calculation, and centrifugal forces implementation on road bends. These actions are lumped through plunging the aftereffect of greater centrifugal force strength. Moreover, this implementation is also able to reduce the chance of accidents due to centrifugal force impacts based on road geometry calculations. Based on the evaluation and implementation of a smaller centrifugal force design, the use of a spiral-circle-spiral bend type with a transition curve can increase safety driving comfort.
