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.

- A six-Lane urban freeway (three lanes in each direction) is on rolling terrain with 11 feet lanes, obstructions to 2 feet from the right edge of the travel pavement, and eight ramps within three miles upstream and three miles downstream of the mid point of the analysis segment. The traffic stream consist primarily of commuters. A directional weekly peak our volume of 2300 vehicles is observed, with 700 vehicles arriving in the most congested 15-min period. If the traffic stream has 15% large trucks and buses and no recreational vehicles, determine the level of serviceA six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions 4 ft from the right edge of the traveled pavement. There are five ramps within three miles upstream of the segment midpoint and four ramps within three miles downstream of the segment midpoint. A directional peak-hour volume of 2000 vehicles (primarily commuters) is observed, with 600 vehicles arriving in the highest 15-min flow rate period.

- A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 5 ft from the right edge. There are zero ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The traffic stream consists of mostly commuters with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service?a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 3.3 meter lanes with a 1.2 meter right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 8% large trucks and buses and 2% recreational vehicles. the driver population factor has been estimated at 0.95. what will the los on this highway be on a 4% upgrade that is 2.4 kilometers long if the speed limit is 90 km/h and there are 9 access points per mileA four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?
- A four-lane undivided multilane highway (two lanes in each direction) has 11-ft lanes, 4-ft shoulders, and 10 access points per mile. It is determined that the roadway currently operates at capacity with PHF= 0.80 and a driver population adjustment of 0.9. If the highway is on level terrain with 8% large trucks and buses (no recreational vehicles) and the speed limit is 55 mi/h, what is the directional hourly volume?A six-lane urban freeway (three lanes in each direction) is on rolling terrain with 11-ft lanes, obstructions 2 ft from the right edge of the traveled pavement, and nine ramps within three miles upstream and three miles downstream of the midpoint of the analysis segment. The traffic stream consists primarily of commuters. A directional weekday peak-hour volume of 2300 vehicles is observed, with 700 vehicles arriving in the most congested 15-min period. If the traffic stream has 15% large trucks and buses and no recreational vehicles and at some point, further along the roadway there is a 6% upgrade that is 1.5 mi long. (assuming that the proportion of vehicle types and the peak-hour factor remain constant) Determine the FFS value in mi/hDetermine the PHF or Peak Hour FactorDetermine the fHVDetermine the value of vpAn existing six-lane divided multilane highway with a field-measure free-flow speed of 45mph serves a peak-hour volume of 4,000 vehicles per hour, with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service for this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.
