An equal-tangent vertical curve is to be constructed between grades of -2.0% (initial) and +1.0% (final). The PVI is at station 110 + 00 and at elevation 420 ft. Due to a street crossing the roadway, the elevation of the roadway at station 112 + 00 must be at 424.5 ft. Design the curve.

An equal-tangent crest vertical curve is 1100 ft long and connects a +2.5% and a -1.5% grade. If the design speed of the roadway is 85 mi/h, determine the length of curve, does this curve have adequate passing sight distance?

Determine the minimum length of a sag vertical curve between a -1.06% grade and + 2.1% for a road with 110 kph design speed. The vertical curve must provide 200 m sight distance

Consider the same vertical curve from Problem 1 that has a +3.2% initial grade and -1.1% final grade. The point of vertical intersection is at station 98+20. The highest point of the curve is at station 100+79.35 to meet drainage design. What is the station of the point of vertical curvature (Also known as beginning of vertical curve). 92+88.95 92+90.81 92+88.05 (INCORRECT) 92+91.23 This is Question 1:  Consider a vertical curve with a +3/2% initial grade and -1.1% final grade. The point of vertical intersection is at station 98+20. The highest point of the curve is at station 100+79.35 to meet drainage design. What is the design speed, in mph? Correct answer here is 70 MPH

A crest vertical curve will connect a 1.5% grade to a -3% grade with a design speed of 45 mph. Using the SSD (stopping site distance) criterion, what is the minimum length of the curve?

A section of a two-lane highway (one lane in each direction) (12-ft lanes) is designed for 55 mi/h. At one point a vertical curve connects a -2.9% and +1.8% grade. The PVT of this curve is at station 38 + 50. It is known that a horizontal curve starts (has PC) 247 ft before the vertical curve's PVC. If the superelevation of the horizontal curve is 0.08 and the central angle is 39 degrees, what is the station of the PT (express station in the format 0.00, for example, station 10+50 must be expressed as 10.5)?

A horizontal curve is to be designed to connect two tangents on a rural principal arterial with a design speed of 110 km/h. The station of the BC is 545+13.65. It is expected that an existing building will be located at a distance of 15 m from the centerline of the inside lane. Determine the minimum radius that will satisfy the sight distance and superelevation requirements.
