A horizontal curve through level terrain is being
designed for a six-lane road with lanes that are 3.4
m wide. The central angle (Δ) is 40 degrees, the
tangent distance is 155 m, 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
7.0%. What is the stationing of the PC and PT? What
is the safe vehicle speed?
