Question
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 6-ft right-side
shoulder and a 3-ft left-side shoulder. The posted speed is 50 mi/h. Previously, there were 4
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 2200 vehicles with 13% heavy vehicles. After development, the directional hourly volume is
2600 vehicles with the same vehicle percentages and peak-hour factor. What is the LOS before
and after the development?
