A Valley curves are always shorter than summit curves B Valley curves do not need any sight distance check C On a summit curve the road ahead is hidden by the crest itself (a line-of-sight problem), whereas on a valley curve the road ahead is physically visible but only as far as the headlights can illuminate it at night D Headlight illumination is only relevant on multi-lane roads

280

Question

According to the aesthetics/coordination guidance in NRS-2070, why should a sharp horizontal curve be avoided near the apex (crest) of a pronounced summit vertical curve?

A It increases the cost of earthwork B Summit curves structurally cannot support superelevation C It is prohibited only on Class I roads D At a crest, a driver's perception of the horizontal curve ahead is delayed or distorted, effectively reducing the sight distance available to react to the bend

Section 29

Questions 281 - 290

281

Question

Why does NRS-2070 emphasize coordinating horizontal and vertical alignment together rather than designing each independently, even if each individually satisfies minimum standards?
