- QUIZ 3 ▸ A 6-lane urban freeway (three lanes in each direction) is on rolling terrain with 3.3 m lanes, obstructions 0.7 m from the left edge of the travelled pavement, and has 16 interchanges within 100 km. The traffic stream consists primarily of commuters. A directional weekday peak-hour volume of 2400 vehicles is observed, with 745 vehicles arriving in the most congested 15-min period. If the traffic stream has 13% large trucks and 5% buses and no recreational vehicles, determine the level of service.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.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 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.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)A rural freeway has an ideal free-flow speed of 120 km/hr and two-lanes 3.6 m in each direction, with right shoulder lateral clearance of 1.2 m. Interchange are spaced approximately 5 km apart. Traffic consists of 10% trucks & buses and 8% recreational vehs. If the maximum 15-min flow rate is 1760 veh/hr, what is the level of service on a 1.7 km long 3.1% upgrade?
- 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 +/- 0.5Eight 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.Traffic volume is 2578 veh/hr with 687 vehicles arriving in peak 15 minutes.There are tow lanes, 12 percent trucks(30/70 split for SUT/TT), the length of the road is 1.8 miles long with a 3.5 percent grade. calculate the analysis flow rate?
- 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.. Dislike for wrong answersProblem 2. Consider a freeway section with three lanes in each direction and with a length of 1.25mi (2km) and a +5% grade. In this freeway, the directional peak-hour volume is 3,800 veh/h, from which 76 are trucks and 152 are transit buses. The maximum 15-min volume within the hour of analysis is 1,055 vehicles. The lane widths are 12 ft (3.6m), and shoulder widths are 10 ft (3.1m). There are 2 exit ramps and 1 entrance ramp in the 3 miles in the upstream section and 1 exit ramp and 2 entrance ramp in the 3 miles in the downstream section (consider the same ramp density if using international (km) units). All transit buses will be removed from traffic since the transit service will be replaced by a commuter rail service. However, by removing buses, new additional passage car demand is expected. It is estimated that for each removed bus, 7 new passenger cars will be added to the original traffic volume of 3,800 veh/h. Question: Determine the change in speed and traffic density before…Draw a space – time diagram for traffic within a tunnel. Assuming there exist a 2-lane before the tunnel but the tunnel itself is 1-lane and after the tunnel the road returns to being a 2-lane.
