- A California freeway has four lanes in each direction and carries a traffic volume of 4000 veh/h. The lane width is 11 ft, right shoulder lateral clearance is 5 ft, and there are four interchanges in every six miles of this freeway. Each interchange has two ramps, one for entry and one for exit. There is a 1 mile long section of this freeway that has a 6% upgrade. It is known that on this segment 5% of the traffic is SUTs and 5% is TTs. Peak-hour factor (PHF) is 0.90. Determine the LOS for this segment.Briefly describe the traffic characteristics associated with each of the levels of service for basic freeway sections.Divided arterial highway for through traffic with full or partial control of access and generally with grade separations at major intersections.

- During the peak hour on a Class I two-lane highway in rolling terrain, volume northbound(peak direction) are 1300 veh/h and volume southbound are 500 veh/h. The PHF is 0.90, and there are 15% trucks/buses of which 14% are semi-trailers and 5% RVs. Lane widths are 11 ft, and shoulder widths are 4 ft. The roadway section is 5 mi in length, and there are 18 access points per mile. There are 50% no-passing zones and the free-flow speed is 65 mi/h. Determine the PTSF and ATS if the grade in the peak direction is 4.75% upgrade and if it is 4.75% down grade. The difference between free-flow speed and crawl speed is 25 mi/h.A four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?During the peak hour on a Class I two-lane highway, volumes northbound are 1200 veh/h and volumes southbound are 400 veh/h. The PHF is 0.95, and there are 14% trucks/ buses and 4% RVs. Lane widths are 3.35 m, and shoulder widths are 1.2-m. The roadway section is 8-km in length, and there are 12 access points per mi. There are 50% no-passing zones and the base free-flow speed is 96 km/h. Determine the base percent time following in the direction analyzed in percent. Assumc Level terrain.

- A 5% upgrade on a six-lane freeway (three lanes in each direction) is 1.25 mi long. On this segment of freeway, the directional peak-hour volume is 3800 vehicles with 2% large trucks and 4% buses (no recreational vehicles), the peak- hour factor is 0.90, and all drivers are regular users. The lanes are 12 ft wide, there are no lateral obstructions within 10 ft of the roadway, and the total ramp density is 1.0 ramps per mile. A bus strike will eliminate all bus traffic, but it is estimated that for each bus removed from the roadway, seven additional passenger cars will be added as travelers seek other means of travel. a.) What is density, before the bus strike? b.) What is the volume-to-capacity ratio, before the bus strike? c.) What is the level of service of the upgrade segment before the bus strike? d.) What is density, after the bus strike? e.) What is the volume-to-capacity ratio, after the bus strike? f.) What is the level of service of the upgrade segment after the bus strike?An existing six-lane divided multilane highway with a field-measure free-flow speed of 45mph serves a peak-hour volume of 4,000 vehicles per hour, with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service for this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.traffic engineering - Q / A freeway is being designed to carry a heavy volume of 5000 veh / h on a regular weekday in rolling terrain . If the PHF is 0.9 and the traffic consists of 90 % passenger cars and 10 % trucks , determine the number of 12 - ft lanes required in each direction if the highway is to operate at level of service C. The free - flow speed is 70 mi / h , there is no lateral obstruction , and interchanges are 3 mi apart .
