A reverse curve is to be used as an exit ramp for a high speed highway onto a parallel highway. The distance for the transition is to be 9003 ft. The lanes on the high speed and parallel highways are 675 ft apart. If the low speed radius is 63% of the high speed radius, find the central angle and degree of curve for each of the curves involved.

A two-lane highway with a design speed of 106.7 km/h requires a transition curve for a horizontal curve of 550 m radius. The curve is used to connect the tangents that form an external angle of 24 degree. The lanes of the highway are 3.65 m wide and the coefficient of side friction for this design speed is 0.11. The change of grade between the centreline and the edge (i.e. Δg) is limited to 1 over 250 for comfort. Calculate...

A reverse curve is being designed to join two roadways whose centerlines are parallel and 72 ft apart. The two simple circular curve components are identical. The line connecting points x and y in the figure is 500 ft long; line x-y is tangent to the curves at the PRC. The station of the PI1 for the first component curve (point x) is 23+45.67 Determine:  The central angle of each component curve  The length of each component curve...
