A highway with a design speed of 100 km/hr is designed with a sag curve connecting a descending gradient of 3% with an ascending gradient of 5%.

a.) Calculate the required length of the sag curve.

b.) If a bridge structure were to be located within the sag curve, with a required clearance height of 5.7 m, then assuming a driver's eye height of 2 m, and an object height of 0.26 m, calculate the required length of the sag curve.

A vertical crest curve on a single carriageway road with a design speed of 100km/h is to be built in order to join as ascending grade of 3% with a descending grade of 3%. The motorist’s eye height is assumed to be 1.05m while the object height is assumed to be 0.26m. 1. Calculate the minimum curve length required in order to satisfy the requirement of minimum sight stopping distance. 2. Recalculate the minimum curve length with the object height...

An existing equal-tangent sag vertical curve is designed for 60 mi/h. The initial grade is -3% and the elevation of the PVT is 754 ft. The PVC of the curve is at station 134 + 16 and the PVI is at 137 + 32. An overpass is being constructed directly above the PVI. The highway is for cars only (AASHTO minimum and recommended structure clearances do not apply) and the overpass design assumes the driver's eye height is set conservatively...

A developer is having a single-lane raceway constructed with a 180 km/h design speed. A curve on the raceway has a radius of 320 m, a central angle (D) of 30 degrees, and PI stationing at 11+511.200. If the design coefficient of side friction is 0.20, determine the superelevation required at the design speed? Make sure you use the exact equation for R and not the approximate equation for R. Include a discussion (a short paragraph) of why this important....
