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.

(25 points) As a junior roadway engineer, you have been asked to
contribute to the design of a section of roadway that runs through
a national park. An endangered deer population has been identified
in the area and a wildlife underpass under a vertical curve has
been proposed, as shown in the figure below. An existing underpass
is perpendicular to the roadway at station 20+91.00 (not
necessarily under the center of the curve). The top of the
underpass...

Problem 1 (15vpts) A proposed highway has two tangents of bearings N 75° 54' 36" E and N 53° 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve to join these tangents, decides that the external ordinate is to be 78.00 ft. The Pl is at station 65+43.21. Determine: (a) The external angle of the curve (A) (b) The radius of the curve (d) The station of the PC (f) The...
