A Class I two-lane highway has a base free-flow speed of 110 km/h. Lane width is 3.6 m, and shoulder width is 2.4 m. There are six access points per kilometre. The roadway is located in rolling terrain with 40 percent no-passing zones. The two-way traffic volume is 1000 veh/h, with a PHF of 0.90. The directional split is 70:30. Traffic includes 10 percent trucks and 5 percent recreational vehicles. The length of the analysis segment is 9.5 km. Determine the total travel time for all vehicles on the analysed segment during the peak 15-min period (veh-h).
