A four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?
