A rural collector highway is to be constructed in an area of rolling terrain where the ADT is 950 veh/day. For this situation, determine the following design values: a. Minimum design speed b. Desirable lane width and shoulder width c. Maximum desirable grade
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).
A divided multilane highway is being designed on rolling terrain. The LOS is desired to be no worse than LOS C. The highway will have five access points per mile, 11-ft lanes, a 4-ft shoulder on the right side, and 2-ft shoulder on the left. The peak-hour factor is 0.84 with 13% heavy vehicles. How many lanes should be constructed if the expected DDHV is 4000 vehicles/hr
1. An existing urban freeway in rolling terrain is to be analyzed to determine LOS using the following information: Number of lanes in each direction: 3 Peak hour volume: 3500 veh/h (in the peak direction, mainly commuter traffic) 8% trucks 0% recreational vehicles PHF=0.95 Lane width: 11 ft Lateral clearance: 4 ft Average interchange spacing: 1.0 mile Base FFS: 65 mph
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.
Civil Engineering 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 particular roadway segment has a 6000-ft section of 3% upgrade, followed by a 5000-ft section of 5% upgrade. The traffic on the road includes 8% trucks and 4% recreational vehicles. Determine the PCEs.
A freeway is to be designed to provide LOS C for the following conditions: design hourly volume of 5600 veh/h; PHF: 0.92; trucks: 6%; free flow speed: 70 mi/h; no lateral obstructions;rolling terrain; total ramp density of 0.75 ramps per mile.Determine: whether eight (four in each direction) 12 ft lanesare enough to provide LOS C.
A long segment of suburban freeway is to be designed on level terrain. The level segment, however, is followed by a 4.5% grade, 2.0 miles in length. If the DDHV is 2,500 vehicles per hour with 15% trucks (standard mix), how many lanes will be needed on the (A.) Upgrade, (B.) Downgrade, (C.) Level terrain segment to provide for level of service C? Lane widths and lateral clearances may be assumed to be 12 feet and 6 feet, respectively. Ramp density is expected to be 1.0 ramps per mile. The PHF is 0.92. Good weather, no incidents, no work zones, and regular users of the facility may be assumed.
A six-lane freeway (three lanes in each direction in mountainous terrain has 10-ft lanes and obstructions 1ft 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 commuter with a peak hour factor of 0.84, peak-hour volume of 2500 vehicles, and 4% recreational vehicles. What is the level of service?
