Class II two-lane highway needs to be redesigned for an area with rolling terrain. There are 380 vehicles traveling in the analysis direction and 300 vehicles are traveling in the opposing direction. The PHF is 0.92. The traffic stream includes 8% large trucks, 2% buses and no recreational vehicles. What is the maximum percentage of no- passing zones effect (fnp) that can be built into the design with LOS D maintained?

using vp= V/PHF • fg • fhv
NOT vp= V/ PHF •N• fhv

Due to network-wide construction work zones, road maintenance planners are considering diverting truck traffic from other roads to a four-lane highway which has two lanes in each direction and is on a level terrain. The road maintenance planners would like to utilize the maximum possible flow rate and keep the four-lane highway at LOS C, which is the minimum acceptable LOS in the district. The adjusted free flow speed is 60 miles per hour. The peak hour factor is 0.88,...

Answer the following question about a basic freeway segment based on Highway Capacity Manual 2016 (assume right-hand traffic and use U.S. customary units): A six-lane freeway (three lanes in each direction) operates at the maximum service flow rate (MSF) of LOS D conditions during the peak hour with an observed demand volume of 3500 veh/h (one direction). The free flow speed (FFS) of the freeway is estimated to be 65 mi/h. The freeway is on rolling terrain and the traffic...

An urban circumferential freeway is to be designed on the basis of the following information: design year average annual daily traffic, AADT = 75,000 veh/day; the estimate of the percent of traffic occurring during the peak-hour is 9%; the percent of peak-hour traffic in the heavier direction is estimated to be 55%. The traffic mixture is expected to be similar to the current mixture of 7% trucks, 3% buses and no recreational vehicles. The PHF is estimated to be 0.9....
