CIVL 261 – Traffic and Transportation Engineering Tutorial Quiz 7B April 1, 2009 Name : Student ID : Geometric Design of Highways – Horizontal Curve A horizontal curve through mountainous terrain is being designed for a four-lanes road with lanes that are 3.0m wide. The central angle ( Δ ) is 40 degrees, the tangent distance is 155m, and the stationing of the tangent intersection (PI) is 7 + 270.000. Under specified conditions and vehicle speed, the roadway surface is determined to have a coefficient of side friction of 0.08, and the curve’s super-elevation is 9.0%. What is the stationing of the PC and
