Concept explainers

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.

Question

A horizontal curve is being designed for a new two-lane highway (3.6-m lanes).
The PI is at station 7 + 640, the design speed is 105 km/h, and a maximum superelevation of
0.08 m/m is to be used. If the central angle of the curve is 35 degrees, design a curve for the
highway by computing the radius and stationing of the PC and PT.

A simple circular curve exists with a degree of curve D = 12º and e = 0.08. A structure is proposed on land on the inside of curve. Assume the road is on level grade. Determine: (a) The radius of the curve (b) The current maximum safe speed of the curve (c) The minimum distance allowable between the proposed structure and the centerline of the curve such that the current maximum safe speed of the curve would not need to be reduced
Design a vertical curve (i.e., Determine length of the curve as well as station and elevation of the vertical curve's PVC and PVT) with the given PVI (station and elevation given the figure below) to go through a future intersection location at the point at which the vertical curve is flat. Report the vertical curve's design speed to the nearest 5 miles per hour. PVC Future Intersection Station = 100+00 G1 = -2.6% PVT PVI G2 = 1.0% Station = 99+00 Elevation = 228 ft %3|
A horizontal curve on a four-lane (two lane in each direction) highway (11-ft lanes) has PC at station 124+30 and PT at station 130 + 15. The central angle is 40 degrees, the superelevation is 0.12, and 23.5 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
4. Horizontal Curve: P.C. 12+00.00 P.I T 4= 30° P.T. This highway has a 60 mph speed limit requiring a minimum radius for any curve to be 1500'. If the curve is to begin at Station 12+00.00 and is to have a radius of 1610.10', how long will the curve be? At what station will the PI and PT go? How long will E be? (Answers should all be in hundredths.)
this is one question split by parts a and b.
A vertical curve is required to join a road with + 2.5% grade to a road with -3% grade. The design speed of the road is 90 kmph and safe stopping sight distance is 180 m on the road. The coordinates of VPI is (500 m, 100 m), with respect to a fixed bench mark. The horizontal co-ordinate of highest point of curve with respect to fixed benchmark is m. (rounded off to two decimal place)
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)?
