A four-lane rural freeway segment has a 510 m grade length of 2% upgrade followed by a 630 m grade length of 3%. The freeway has 3.4-m lane, 1.5m left-shoulder lateral clearances and interchanges spaced at every 25 km. During the peak hour, there are 6% trucks, 2% buses, 2% recreational vehicles and the rest are passenger cars. Driver population adjustment is determined to be 0.90, peak hour factor is 0.90 and the BFFS is 110 km/h. At present, the freeway operates at capacity during the peak hour in the direction in question. If an additional 3.4 m lane is introduced, and all other factors stay the same, what will be the new level of service?
A six-lane divided highway (three lanes in each direction) is on level terrain with 6 access points per kilometer and has 3.6-m lanes, with a 1.2-m shoulder on the right side and a 0.6-m shoulder on the left side. The peak-hour factor is 0.80, and the directional peak-hour volume is 3,500 vehicles per hour. There are 5% large trucks and 3% recreational vehicles. A significant percentage of non-familiar roadway users are in the traffic stream (the driver population adjustment factor is estimated as 0.85). No speed studies are available, but the posted speed limit is 80.5 km/h. Determine the level of service.
traffic engineering - Q / A freeway is being designed to carry a heavy volume of 5000 veh / h on a regular weekday in rolling terrain . If the PHF is 0.9 and the traffic consists of 90 % passenger cars and 10 % trucks , determine the number of 12 - ft lanes required in each direction if the highway is to operate at level of service C. The free - flow speed is 70 mi / h , there is no lateral obstruction , and interchanges are 3 mi apart .
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 four-lane undivided highway (two lanes in each direction) has (3.4m) lanes, with (1.2 m) shoulders on the right side. There are 4.5 access points per km, and the posted speed limit is 80 km/h. What is the estimated free-flow speed?
A four-lane divided multilane highway (two lanes in each direction)in rolling terrain has the following additional characteristics:• BFFS of 60 mi/h (100 km/h)• No access points• 12-ft lanes (3.6m)• 8-ft (2.4m) shoulder on the right side and 6-ft (1.8m) shoulder on the left• The peak-hour factor is 0.84• The traffic stream consists of 6% trucks, 4% buses and 3% recreational vehicles.• The driver population adjustment factor is estimated at 0.90.• Analysis flow rate is 1250 pc/h/ln. i) A new urban development will be built in the proximity of this highway section. This development will require the addition of 20 access points per mile (12 access points per km) but all other conditions (geometry and traffic) will stay the same. What is the differential (change) in the average speed (S) before and after the urban development?
A freeway is being designed to carry a heavy volume of 5000 veh/h on a regular weekday in rolling terrain. If the PHF is 0.9 and the traffic consists of 90% passenger cars and 10% trucks, determine the number of 12-ft lanes required in each direction if the highway is to operate at level of service C. The free-flow speed is 70 mi/h, there is no lateral obstruction, and interchanges are 3 mi apart.
One segment of a Class I two-lane highway is on rolling terrain and has an hourly volume of 950 veh/h (total for both directions), a directional traffic split of 70/30, and PHF = 0.85, and the traffic stream contains 6% large trucks, 3% buses, and 6% recreational vehicles.
A six-lane freeway (three lanes in each direction) in rolling terrain has 10-ft lanes and obstructions (fLw = 6.0 mph) 4 ft from the right edge of the traveled pavement (fic = 0.8 mph). 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. The traffic stream contains 12% large trucks (ET = 2.5) and buses and 6% recreational vehicles (ER = 2.0). 1.) What is the estimated free-flow speed of the traffic stream in mph (whole number, nearest 5)? 2.) What is the peak-hour factor 3.) What is the heavy-vehicle adjustment factor? 4.) What is the service flow rate? 5.) What is the service measure value if the average speed of the traffic stream is 65 mph
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?
A six-lane freeway (three lanes in each direction) has regular weekday users and currently operates at maximum LOS C conditions. The lanes are 3.5m wide, the right-side shoulder is 1.2 m 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 rolling terrain with 10% large trucks and buses (no recreational vehicles), and the peak-hour factor is 0.90. a) Determine the hourly volume for these conditions. b) At one point along this freeway, there is a 4% upgrade with a directional hourly traffic volume of 5000 vehicles. How long can this grade be without the freeway LOS dropping to F?
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?
