A freeway segment with largely level terrain has an observed free-flow speed of approximately 70 mph. There are three lanes in each direction, a 3-ft lateral clearance, and approximately 1 interchange per mile. You collect some data and observe a volume of 3080 veh/h with a corresponding PHF = 0.88. You counted 154 trucks and buses and no RVs. From the driver behavior and what you already know about the area, you assume the drivers are all commuters. What is...
