- A lot a complains from drivers and passengers have come concerning an uncomfortable weight loss sensation usually experienced at a particular sag curve. how would one redesign this sag curve to eliminate the weight loss sensation.3-19 The radius of a horizontal curve on an existing highway was field-measured to be 243 m. The pavement on this two-lane highway is 6.6 m wide, and the elevation difference between the inside and outside of the curve is 0.43 m. The posted speed limit on the road is 96 km/h. Is this a hazardous location? If so, why? What action will you recommend to correct the situation?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?
- 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?Discuss your point of view of the 3 kinds of horizontal curve, which is the easiest to analyze and which is dangerous curve of them all in actual roadway?If a four legged roundabout has 8 conflict points, how many does a 3 legged roundabout? From Highway Engineering
- The crossing of traffic streams moving the same general direction accomplished by merging and diverging. Undercrossing Travel way Weaving Flared intersectionDiscuss your point of view of the 3 kinds of horizontal curves, which is the easiest to analyze and which is the dangerous curve of them all in the actual roadway?Question 5a) As the Area Engineer of Ghana Highway Authority, a lot a complains from drivers and passengers have come to you concerning an uncomfortable weight loss sensation usually experienced at a particular sag curve. You have therefore been tasked to redesign this sag curve to eliminate the weight loss sensation. How would you achieve this objective?
- The radius of a horizontal curve on an existing highway is 230 m. The superelevation rate at the curve is 0.08, and the posted speed limit on the road is 100 km/h. Justify that this is a hazardous location Provide any two (2) possible actions that you would recommend to correct the situation i. ii.How many methods are there to distribute e and fs? What is different about each method? How long is a WB-67 and what is the min distance from the left wheel path to edge of pavement to assume no off tracking? What is the most common reason for bridge failures according to NDDOT Hydraulics SectionA new transportation engineer is charged with the design of a horizontal curve a certain highway. His final design calls for a curve with a radius of 520 meters. Assume that the design speed for the highway is 110 km/h. Is the design curve acceptable? Consider super elevation of 8% and a maximum side friction factor of 0.1.
