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 the directional hourly volume was 2400 vehicles with 8% large trucks and buses and 5% recreational vehicles. After the development, the peak-hour directional flow is 2800 vehicles with the same vehicle percentages and PHF. What is the level of service before and after the development?

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...

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...

[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...
