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?

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.
One segment of a Class I two-lane highway is on level terrain and has an hourly volume of 1200 veh/h (total for both directions), a directional traffic split of 50/50, and PHF = 0.92, and the traffic stream contains 5% large trucks, and 2% buses. It has 11-ft lanes, 2-ft shoulders, access frequency of 10 per mile, 50% no-passing zones, and a base FFS of 55 mi/h, determine the level of service for this two-lane highway segment.
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.
An existing four-lane freeway in rural area is with the following :information Lane width 3.5m, 0.9m lateral clearance, 1800 veh/hr peak hour volume, PHF=0.9, interchange density =0.90, 5% trucks, 5% buses and the road is within a mountainous terrain. Then based on the HCM procedure, the service flow rate (pc/h/In) is
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 2-lane highway has lane widths of 2.75m, with 1.83m clear hard shoulders. There are no-passing zones along 40% of its length. The directional split is 60/40 in favour of the peak direction. The percentages of the various heavy vehicles types are: Trucks PT – 10%, Buses PB – 4%, Cars Pc – 2%. The terrain is rolling; calculate the service flow of the highway when running at full capacity
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 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 six lane undivided highway (three lanes in each direction) road on a level terrain has 3.4 m lanes, 1.2 m obstruction within the right edge and 0.6 m obstruction within the left edge lateral clearance of the traveled pavement, with 12.4 access points per kilometer. The posted speed is 84.06. Hourly volume averages on a 3,712 vehicles and 772 on the most congested 15-min period. If 11.84% and34.35% contains the traffic stream for heavy vehicles and recreational vehicles, compute the original free flow speed.
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?

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.)
