A horizontal curve is to be designed for a two-lane road in mountalnous terrain. The following data are known: Intersection angle: 55 degrees, tangent length = 850.26 ft, station of PI: 2,700 + 10.65,
f, - 0.12, e - 0.08. Determine the following.
(a) design speed (In mi/h)
70
mi/h
(b) station of the PC (Enter the first answer exactly, and round the second answer to at least one decimal place.)
2700
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit
accuracy to minimize roundoff error. + 10.15
Your response differs from the correct answer by more than 10%. Double check your calculations.
(c)
station of the PT (Enter the first answer exactly.)
(d) deflection angle (in degrees) and chord length (in ft) to the first 100 ft station
deflection angle
chord length
