(2 points) A horizontal curve on a two-lane highway (12-ft lanes) is designed for 55 mi/h with a 6% superelevation. The central angle of the curve is 50 degrees and the PI is at station 212+67. What is the station of the PT? Determine the length of superelevation runoff and tangent runout for the associated curve transition section (assume a normal, 2% crown). Assume perception-reaction time of 2.5 sec and the deceleration rate for braking (a) is 11.2 ft/sec2

An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 17.88 m/s (40 mi/hr), does not depend on friction to round the curve without skidding. The radius of the curve is 230 m. At what angle with respect to the horizontal must the curve be banked (in degrees)?

A horizontal curve on a two-lane highway (12 ft lanes) has a PC at station 123+80 and PT as station 129+60. The central angle is 30 degree, the super-elevationis 0.06 and 22 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum sate speed (assuming current design standards) to the nearest 5 mi/h.

Problem 4. A section of a two-lane highway has 12-ft lanes and a design speed of 75 mi/h. The section contains a vertical curve and a horizontal curve. The vertical curve connects a-2.5% grade and a +1.5% grade. The PVT of this vertical curve is at station 36 + 50. The PC of the horizontal curve is located 294 ft before the PVC of the vertical curve. The horizontal curve has superelevation of 8% and central angle of 38 degrees....
