Question

Vertical Alignment

You are to use a 2010 Ford Taurus to address the following:

ρ = air density at 0 ft altitude and 59 °F.

A_f = 20.2 ft²

W= 5200 lb

θg = 0

Other factors not given should be feasibly assumed

Tables and equations are numbered following the 5ed. of Principles of Highway Engineering and Traffic Analysis textbook.

Use the practical SSD and K-values (Tables 3.1, 3.2, 3.3) for 70 mph on crest and sag curves assuming your car is on poor, wet pavement and has ABS (use the ηb=0.95). Include aerodynamic resistance (Use Eq. 2.42), and assume SSD < L (do not forget to add perception/reaction time to your computed stopping distance).
