A divided multilane highway in a recreational area has four lanes (two lanes in each direction) and is on rolling terrain. The highway has 10-ft lanes with a 5-ft right-side shoulder and a 3-ft left-side shoulder. The posted speed is 55 mi/h. Previously, there were six access points per mile, but recent development has increased the number of access points to 12 per mile. Before development, the peak-hour factor was 0.95, and the directional hourly volume was 2300 vehicles with 15% heavy vehicles. After development, the peak-hour directional flow is 2700 vehicles with the same vehicle percentages and peak-hour factor.

1. What is the LOS before and after the development?
