Step by step
Solved in 2 steps
- Determine the total stopping distance (ft) for a road with speed limit of 79mph and grade of -2.5%A 6-mile two lane highway in rolling terrain has the following data: Volume = 1500 veh/hr (two way); PT = 14%; PRV = 4%; peak fifteen minute volume is 415 vehicles. Percent no passing is 60% for a 50-50 directional split; lane width is 10.5ft, with a shoulder width of 4-ft; access points = 20 per mile. Assume the base free flow speed measured on the field is 65 mph. Determine the free flow speed at the highway section in mph.Q2/ A 3200 ft segment of 3.25-mi four-lane undivided multilane highway in a suburban area is at a 1.5% grade. The highway is in level terrain, and lane widths are 11 ft. The measured free-flow speed is 46.0 mi/h. The peak-hour volume is 1900 veh/h, PHF is 0.90, and there are 13% trucks and 2% RVs. Determine the LO, speed, and density.
- Problem Determine the level of service? for six lanes undivided level highway. The width of lane, shoulder on the right side, and shoulder on the left side are 10 ft, 2 ft, and 2 ft respectively. The directional hour volume is 3500 Veh/h. The traffic composition includes 15% trucks and 1% RVs. The peak hour factor is 0.80. Unfamiliar drivers use the road that has 10 access points per mile. The design speed is 55 mi/h. Discuss possible modifications to upgrade the level of service? (Verify your answer)Determine the PTSF in each direction for a 4.5 mi (7.2 km) two-lane highway segmentin level terrain. Traffic volumes (two-way) are 1100 veh/h. Trucks: 10%; RVs: 7%; PHF:0.97; directional split: 60/40; no passing zones: 40%.An existing four-lane freeway in rural area is with the following :information Lane width 3.5m, 0.9m lateral clearance, 1800 veh/hr peak hour volume, PHF=0.9, interchange density =0.90, 5% trucks, 5% buses and the road is within a mountainous terrain. Then based on the HCM procedure, the service flow rate (pc/h/In) is
- What is the safe stopping distance for a section of rural freeway with a design speed of 80 mi/h and maximum coefficient of skidding (forward) friction on: a) Level terrain b) 4% upgradeIf 420’ are available as Sight distance on an urban highway having a 2.5% grade. Assuming all the parameters according to ASHTO, find maximum speed which can be posted on the highway for safe travelling.A two-lane minor road intersects a two-lane undivided major road at 90 degrees, forming a four-leg intersection with traffic on the minor road controlled by a yield sign. A building is located 50 m from the center line of the outside lane of the major road and 14 m from the center line of the nearest lane of the minor road. A passenger car on the minor road would like to cross the major road. Using the AASHTO procedure, determine the maximum speed that can be allowed on the minor road if the design speed on the major road is 80 km/h. Assume a 3% approach grade for the minor road. Note: 1km/hr = 0.62mi/h, 1ft = 0.3048m
- A minor 2-lane roadway with design speed of 45 mph crosses a major 2-lane roadway with design speed of 50 mph at 90 degree angle at an at-grade T-intersection. All lanes are 12 ft wide. If a stop sign is installed on the minor road, determine the dimensions ofallrequired clear sight triangles at this intersection for passenger cars(Case B, stop sign control on the minor road).2.6-What is the safe stopping distance for a section of rural freeway with a design speed of 80 mi/h on a 4% upgrade? (Ans. 902.63 ft)Qu. A two-lane minor road with a +5% approach grade intersects with a four-lane undivided road. Determine the minimum intersection sight distance on the major road required for a stopped single-unit truck to depart from the minor road (in the upgrade direction) and turn right onto the major road. The design speed is 30 km/h on the minor road and 50 km/h on the major road.
