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.

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.)
A curve of 100 m radius (e=8.0 % and fs=0.14) is located at a section of an existing rural highway which restricts the safe speed to 55 % of the design speed causing a high accident rate. To reduce the accident rate, a new curve is to be designed. Determine the minimum radius of this curve if the safe speed should be increased to the design speed. Assume the same values of e and fs.
