- On a proposed highway, the speed limit is 120 km/hr, radius of a horizontal curve on this proposed highway is 250 m and the superelevetion is 8%. Is there any design problem? If so, what the action will you recommend to correct the design?Are roundabouts applicable for high speed approaches? Find an example on line. from Highway EnginneringA highway crew measures the radius of curvature at a tight corner in a highway as 900 feet. What is the maximum safe speed?
- 47 Determine the impact factor for a highway curve having a radius of 1,997 ft and maximum design speed of 56 kph. Express your answer in 4 decimal places.Compare and contrast diamond, trumpet, single point diamond, cloverleaf interchanges. Include a discussion of advantages and disadvantages of each.Exit 63 of I-90 includes a tight loop ramp with a radius 250 ft. The advisory exit speed is 30 mph. how much superelevation needs to be provided to allow safe travel on this exit ramp? stay with the same units, I got e = 0.44, just want to double check
- Answer the following: List: The two primary distinguishing features that differentiates a modern roundabout from a traffic circle Two appropriate types of locations to install a modern roundabout. Two inappropriate types of locations to install a modern roundabout.An eight-lane freeway section is designed to have a lane width of 12 ft, right-side shoulder width is 3 ft, and 3 ramps over a 2-mile-long centerline. What is the free-flow speed for this freeway section? a. 75 mph b. 70 mph 65 mph O d. 60 mph C.In the simple highway network shown, the cost function (C) depends on the link traffic flow (f). C6=2+2f6 C₁-3+4f4 A C₁=3+4f₁ If f2=34, compute the value of C5. Cs=6+4fs B C₂-6+3f₂ C₁=6,+6f3 D
- you are a Highway Engineer and you have to design a road with a horizontal curve, how much super-elevation would you provide for a curve of radius 40 meter and design speed of 60 Kmph. If you cant provide max super-elevation what other checks or remedies would you provide?55 mph roadway with two northbound through lanes (both are 11 feet in width) through an intersection. Beyond the intersection, the lanes merge into one lane. Please calculate the merge taper AND the distance the sign must be place AHEAD or upstream of the beginning of the merge. Pls hand written solutionState the principal difference between interchange and other forms of intersection.
