- During The Peak Hour On A Class I Two Lane Highway In Rolling Terrain Volume Northbound Peak Direction Are 1300veh H A 1 (69.93 KiB) Viewed 46 times
During the peak hour on a Class I two-lane highway in rolling terrain, volume northbound(peak direction) are 1300veh/h and volume southbound are 500veh/h. The PHF is 0.90, and there are 15% trucks/buses of which 14% are semi-trailers and 5% RVs. Lane widths are 11ft, and shoulder widths are 4ft. The roadway section is 5mi in length, and there are 18 access points per mile. There are 50% no-passing zones and the free-flow speed is 65mi/h. Determine the PTSF and ATS if the grade in the peak direction is 4.75% upgrade and if it is 4.75% down grade. The difference between free-flow speed and crawl speed is 25mi/h
