- You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS C using the 40th highest annual hourly volume (K = 0.116).

- Eight lane urban freeway is on mountainous terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the heavy vehicle adjustment factor. Round your answer to 3 decimal places. Exclude the unit in the answer box.You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics.

Determine the number of lanes (both directions) required to provide at least level of service D using the 30th highest annual hourly volume (K30+ 0.12). The answer is a number of lane freeway.A six-lane freeway (three lanes in each direction) in a scenic area has a measured free-flow speed of 55 mi/h. The peak hour factor is 0.80, and there are 8% large trucks and buses and 6% recreational vehicles in the traffic stream. One upgrade is 5% and 0.5 mi long. An analyst has determined that the freeway is operating at capacity on this upgrade during the peak hour. If the peak hour traffic volume is 3900 vehicles, compute for the driver population factor used?
