Tubibi Highway is a Class II Two-lane highway that is considered a level terrain. Based on the data, 1,631 passenger cars travel on average per hour for both directions with a directional split of 50/50. A maximum of 388 passenger cars is recorded within a 15-min time segment of the peak hour. The traffic stream contains 2% large trucks, 3% buses, and 3% recreational vehicles. Determine the opposing direction flow rate in pc/hr. Answer in two decimal places. 2,953.65 776 margin of error +/- 0.5
Eight lane urban freeway is on mountainous 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 familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the density in pc/mi/In. Round your answer to 3 decimal places. Exclude the unit in the answer box.
