A signalized intersection approach has a saturation flow rate of 1,800 veh/h/lane, a green ratio (g/C) of 0.45, and a volume of 600 veh/h in a single lane. The volume-to-capacity (v/c) ratio for this approach is most nearly:
A horizontal curve on a two-lane highway has a radius of 300 m and a design speed of 80 km/h. Using a maximum superelevation rate of 8%, the minimum required side friction factor per AASHTO is most nearly:
A stopping sight distance calculation assumes a perception-reaction time of 2.5 seconds and a deceleration rate of 3.4 m/s². For a design speed of 100 km/h, the stopping sight distance is most nearly:
