  1. A series of vertical curves connect a 3% upgrade, a 2% downgrade, and another 3% upgrade moving west to east. These curves are designed such that they connect directly to one another (i.e., the PVT of the first curve is the PVC of the second curve). If the design speed of the alignment is 60 mi/h, what is the elevation difference between the two road segments (i.e., the vertical difference between the PVC of the first curve and the PVT of the second curve)? (20 points)

3.40 A crest and sag curve connect a 0% west highway segment (left) with a +2% east highway segment (right). The 0% west highway segment is at a higher elevation than the start of the +2% east highway segment. The two vertical curves connect with each other (PVTc = PVCs) and share a 3% common grade. If the design speed of the curves is 45 mi/h, what is the elevation difference between the two road segments?

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...

Determine the minimum length of a vertical curve necessary for it to be adequate, under the visibility criteria for braking, for a design speed of 80 mph. The slopes corresponding to the PVC and PVT of the curve in question are 4% and -3% respectively. the PVI station is 120 + 70 and its elevation is 810 meters. The coefficient of lateral friction is 0.08. All circular curves in the segment under study have been designed using an 8% superelevation...

3.9) Two level sections of an east-west highway (G=0) are to be connected. Currently, the two sections of highway are separated by a 1200m (horizontal distance) ,2% grade.the westernmost section of highway is the higher of the two and is at elevation 30m. If the highway has a 100km/h design speed, determine, for the crest and sag vertical curves required, the stationing and elevation of the PVCs and PVTs given that the PVC of the crest curve (on the westernmost...

Part I. Indicate whether true or false (T or F). ____ Storm water detention ponds typically are designed to regulate the outflow peak rate at or below a single target value, such as the pre-development (pre-land use change) peak runoff rate for a specified return period event. Detention storage alters the peak but not the volume of the outflow hydrograph. _____ Typical rating curves for weirs are concave upward. Typical rating curves for orifices are concave downward. ____ A sediment...
