A vertical curve will be designed. The road is divided state road and has two lanes in each direction. The design speed is 120 km/h, the driver perception and reaction time is 2 sec, the grades are 3% and -5,5 %, the friction coefficient is 0,40, elevation of point of intersecting is 100 m. If necessary, the safety distance: d= 8+0,2V.
Decide the the vertical curve type and draw the skecth of the vertical cuve
