The 2 southbound lanes of a four-lane (i.e. 2 lanes each direction) urban freeway are 12 ft wide. There is at least 6 ft of lateral clearance on the right side of the outer/right lane. There are two ramps within the influence area (i.e. within 3 miles upstream and 3 miles downstream of the center of the segment. What is the estimated FFS (mph)? Provide the answer to the nearest tenths. Response Feedback: The BFFS of 75.4 mph is reduced by 1.28 mph to account for the presence of ramps.

(a) A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 11 ft wide, the right-side shoulder is 4 ft wide, and there are two ramps within three miles upstream of the segment midpoint and one ramp within three miles downstream of the segment midpoint. The highway is on rollingterrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. Determine the hourly volume for these conditions.
QUESTION 1 A four-lane urban freeway segment has a peak demand volume of 3,500 vehicles per hour for the two eastbound lanes. The PHF is 0.95 and there are no trucks, buses or RVs because the freeway is classified as a parkway and such vehicles are prohibited. The segment has 12 ft lanes, no lateral obstructions, 3 ramps within the influence area, and meanders through some beautiful rolling terrain. Assuming the road will be used by commuters and those familiar with the road, what is the flow rate (pcphpl)? Provide your answer to the nearest integer.

A basic segment of a rural freeway has the following characteristics: • Four-lanes (two lanes in each direction)%3B There is one ramp within 3 miles upstream, and 2 ramps within 3 miles downstream; 10-ft lanes; Right shoulder width of 4 ft; • Level terrain;. 10% trucks and 5% buses in the vehicle stream. Calculate the FFS at this freeway section and then determine the level of service (LOS) when the flow rate is 1740 pc/h/In. (Write the answer for the LOS in the box below).
QUESTION 5 A segment of rural freeway is being designed for a FFS of 65 mph using 11 ft lanes in a mountainous area. The lateral clearance is nominal (1 ft). The directional (i.e. one-way) design flow rate is expected to be 2,400 passenger cars per hour. How many lanes in one direction will be needed to provide at least a LOS B?
