6.11 A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 6% large trucks and buses and 2% recreational vehicles (fp = 0.95). If the peak-hour factor is 0.85, determine the highway's level of service.

Q3. A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10% buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B). how many lanes must be provided to satisfy the design requirement?
A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 8% heavy vehicles. If the peak-hour factor is 0.85, determine the highway’s level of service. Answer: LOS:C
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.

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 exact demand flow rate (in pc/h/In). Round your answer to 3 decimal places. Exclude the unit in the answer box.
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
A portion of the extension of SLEX has a free flow speed of 60kph and a capacity of 3600 veh/hr. If in a given hour, 3344 vehicles were countered at a specified point along this highway, determine the traffic density of these 3344 vehicles.
Problem 2: A Class III two-lane highway is on level terrain, has a measured free-flow speed of 45 mi/h, and has 100% no-passing zones. During the peak hour, the analysis direction flow rate is 150 veh/h, the opposing direction flow rate is 100 vehh, and the PHF = 0.95. There are 5% large trucks and 10% recreational vehicles. Determine the level of service.
A Four Lane freeway is located on rolling terrain with a free flow speed of 70 mph,12ft lanes, and no lateral obstructions within 8 ft of the pavement edges. the traffic stream consists of cars, buses and large trucks (no recreational vehicles) . A weekend directional peak hour volume of 1800 vehicles (*regular users*)is observed ,with 700 arriving in the mostly congested 15 minutes period . if a level of service no worse than C is required ,determine the maximum number of large trucks and buses that can be present in the peak hour traffic stream..

There are 9 vehicles observed in a 300 m section of McArthur highway. If the average time headway is 4 sec., compute the space mean speed of the vehicles in kph.
There are 5 vehicles observed in a 100 m section of McArthur highway. If the average time headway is 3.6 sec., compute the space mean speed of the vehicles in kph. Answer in whole number.
A six-lane freeway (three lanes in each direction) in mountainous terrain has 10-ft lanes and obstructions 1 ft from the right edge. There are five ramps within three miles upstream of the segment midpoint and four ramps 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? (Write the letter only)
