An old divided 6-lane (3 lanes each direction) highway has 11 ft lanes and obstructions leaving no more than 2 ft of clearance on each side of the roadway. There are no driveways or intersections on the segment of interest. Given a posted speed limit of 50 mph, estimate the FFS (mph) for the 3 northbound lanes? Provide the answer to the nearest tenths. Response Feedback: The BFFS of 55 mph is adjusted by 1.9 mph for the 11 ft lanes and adjusted by 1.7 for the total lateral clearance.

Problem.
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..

Problem 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…
The 2 eastbound lanes of a rural divided highway have 13 ft lane widths. There is no lateral clearance afforded on either side of the road. There is an access density of 20 access points per mile. What is the estimated FFS (mph) if the BFFS is 60 mph? Provide your answer to the nearest tenths. Response Feedback: The BFFS is adjusted by 5.4 mph for the lack of lateral clearance and adjusted by 5.0 mph for the access density.
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.
