A horizontal curve is being designed for a new two-lane highway (12-ft lanes). The PC is at station 150+50, design speed is 55 mi/h, and a superelevation of 0.08 fuft is to be used. If the central angle of the curve is 40 degrees, design a curve for the highway by computing the minimum radius and stationing of the PI and PT??
A horizontal curve with a radius of 800 ft connects the tangents of a two-lane Highway that has a posted speed limit of 35 mi/h. If the highway curve is not super elevated, e =0, determine the horizontal sightline offset (HSO) that a large billboard can be placed from the centerline of the inside lane of the curve, without reducing the required SSD. Perception-reaction time is 2.5 sec, and f = 0.35. when S<L and S>L.

A simple horizontal curve has 35 degrees of curvature and subtends an angle of 110 degrees. If the PC is at station 3 + 65.00 ft, what is the last deflection angle (degrees) (i.e. the angle subtended by the roadway between the last full station and the PT)?
The stopping sight distance along four lane two way highway is 250 ft. The highway includes a horizontal curve where the center line of the innermost lane has a radius of 100 ft. The width of each lane is 12 ft and the width of each shoulder lane is 5 ft. What minimum distance (ft) from the innermost edge of the shoulder lane can a large object be placed?

A vertical curve joining a (-5%) and (+3%) grades in a rural highway has a design speed of 100kph. The tangents intersect at a station (225+71.35) at an elevation of 290m. Caleulate the elevations of intermediate points on the curve each 100m, and determine the stations and elevations of PVC, PVT. It s important to know that the driver acceleration rate is 3m/sec2 and the perception & reaction time is 2.5 seconds.
