Eight lane urban freeway is on level terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of unfamiliar road users. Peak hour volume for a directional weekday of 3200 vehicles is observed with 900 vehicles arriving in the most congested 15-min period. If the traffic stream has 20% large trucks and 20% buses and 15% recreational vehicles, determine the density in pc/mi/In. Round your answer to 3 decimal places. Exclude the unit in the answer box.
