A rural freeway has an ideal free-flow speed of 120 km/hr and two-lanes 3.6 m in each direction, with right shoulder lateral clearance of 1.2 m. Interchange are spaced approximately 5 km apart. Traffic consists of 10% trucks & buses and 8% recreational vehs. If the maximum 15-min flow rate is 1760 veh/hr, what is the level of service on a 1.7 km long 3.1% upgrade?
