Question: Consider point A , B , C and D , the coordinate and stationing of Point A is ( 1 0 0 N , 2

Consider point A, B, C and D, the coordinate and stationing of Point A is (100N,200E) and 8+000.000. Point B is at STA 8+400, point C is at coordinate of (200N,300E), point D is at coordinate of (40N,500E). Azimuth of line AB is 9000'00'' as shown in the following figure. A simple curve of undivided two lane highway is designed with 90kmhr design speed, and 300-m radius, 3.5-m lane width. Assume driver's PIEV time equals 2.5 sec and 0.13 of coefficient of friction, determine the attainment of superelevation (stationing and elevation of NC, HC, FC, FS, PC and PT both Superelevation Attainment and Superelevation Removal). If the crown slope is 1.5% and elevation of highway outside edge is 100 m , and the crowned pavement is rotated about the profile of the outside edge. (+15 marks)
