- 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?A road with a design speed of 55 mph has a utility pole located 27 ft from the edge of travel lane. If the ADT for the road is 1,850 vpd and the sideslope slopes down at a 1V:4H grade, is the utility pole located within the clear zone?- What are the major reasons for accidents at curved highway?
