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?
A six-lane multilane highway (three lanes in each direction) has 10-ft lanes with 5-ft shoulders on the right side. There are 10 access points per mile and the posted speed limit is 50 mph. The median is TWLTL. Estimate the free flow speed.
A 6-mile two lane highway in rolling terrain has the following data: Volume = 1500 veh/hr (two way); PT = 14%; PRV = 4%; peak fifteen minute volume is 415 vehicles. Percent no passing is 60% for a 50-50 directional split; lane width is 10.5ft, with a shoulder width of 4-ft; access points = 20 per mile. Assume the base free flow speed measured on the field is 65 mph. Determine the free flow speed at the highway section in mph.
