TRANSPORTATION ENGINEERING: A multilane highway has four lanes (2 in each direction) and a measured FFS of 55 mph. One upgrade is 5% and 0.62 miles long. Currently trucks are not permitted on the road, but there are 2% busses in the directional volume of 1900 vehicles (PHF is 0.80). Local authorities are considering allowing trucks into the traffic stream. If this is done, they estimate 150 trucks will use this highway during peak hour. Before trucks, the driver population factor is 1, and it goes to 0.97 after trucks. What will be the level of service before and after trucks are allowed on the road.

A four-lane undivided multilane highway (two lanes in each direction) has 3.4 m lanes and 1.5 m shoulders. At one point along the highway there is a 4% upgrade that is 1 km long. There are 15 access points along this grade. The peak-hour traffic volume has 2500 passenger cars and 200 trucks and buses (no recreational vehicles), and 720 of these vehicles arrive in the most congested 15-min period. This traffic stream is primarily commuters. The measured free-flow speed...

A divided multilane highway in a recreational area (fp=0.90) has four lanes (two lanes in each direction) and is on a rolling terrain. The highway has 3 m lanes with a 1.8 m right-side shoulder and a 0.9 m left-side shoulder. The posted speed limit is 80 km/h. Formerly there were 3 access points per km, but recent development has increased the number of access points to 9 access points per km. Before development, the peak-hour factor was 0.90 and...

A multilane highway has two northbound lanes. Each lane has a capacity of 1500 vehicles per hour. Currently, northbound traffic is consists of 3100 vehicles with 1 occupant, 600 vehicles with 2 occupants, 400 vehicle with 3 occupants, and 20 buses with 50 occupants each. The highway’s performance function is t = t0 ( 1 + 1.15 (x/c)6.87 ) where t is in minutes, t0 is equal to 15 minutes, and x and c are volumes and capacities in vehicle...

An existing 2-lane (in each direction) multilane divided highway. The speed limit is 50 mi/h, the lanes are 11-ft wide and lateral clearance is 2-ft. The peak hour volume is 1,800 veh/h in one direction, there are 5% trucks, a PHF of 0.92, but 1 access point per mile. a) Determine the LOS during the peak hour. b) Compare your result with the freeway in situation 1.

. A four-lane arterial (with two lanes in each direction) has a capacity of 1000 vehicleshourlane. Due to some road repair work, the maximum capacity of two lanes in the northbound direction is reduced to 1100 veh/hr from 2000 veh/hr for a short length of 200 ft. If the total traffic upstream of the repair site in the northbound lanes is reasonably at 1500 vehhr, find (a the mean speed of traffic through the repair site and (b) the stead...

An existing rural 4-lane freeway (2 lanes in each direction) has 11-ft lanes and 2-ft lateral clearance. The freeway hasa peak-hour volume of 1,800 veh/h in one direction, 5% trucks in the traffic stream, and a PHF of 0.92. The freeway has 1 cloverleaf interchange within three miles of the midpoint of segment, and runs through level terrain. No recent field speed data is available. a) Using HCS7, determine the LOS during the peak hour. b) What is the capacity...

Problem Statement: A four-lane (two-lanes in each direction) freeway is on rolling terrain with 11-ft lanes, a 5-ft lateral clearance on right side and 3-ft lateral clearance on the left side of the traveled pavement. The measured free-flow speed is 60-mph. During the peak hour there are 12% large trucks and buses and 6% recreational vehicles. The freeway currently operates at capacity during the evening peak hour. If an additional 11-ft lane is added, and all other factors stay the same,...

[HCM for Basic Freeway Segments] A four-lane freeway (two lanes in each direction) has an observed demand volume of 2400 veh/h (one direction) during the peak hour. The freeway is on rolling terrain and the traffic stream consists of passenger cars and trucks only. The peak-hour factor is 0.75 and the traffic is all commuters. If the peak 15-min demand flow rate under equivalent base conditions is estimated to be 2000 pc/h/ln, what is the percentage of trucks in this...

A six-lane freeway with three lanes in each direction has regular weekday users. The lanes are 12 feet wide, the right-side shoulder is 2 ft wide, and there are two ramps within 3 miles upstream and two ramps within 3 miles downstream of the segment midpoint. The highway is on rolling terrain with 12% large trucks and buses and 2% recreational vehicles. The peak hour factor is 0.85. Determine the maximum hourly volumes that can be sustained at LOS C...
