During the hour on a class I two-lane highway in rolling terrain, volume northbound (peak direction) are 1300 veh ih and volume southbound are 500 veh/h. The PHF is 0.90, there are 15% trucks busses 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 Free-flow speed is 65milh.
