Question

Setting of leminscate transition curve is done with?

Answer 1

Cubic spiral——————————————->length of curve measured on the curve itself with first term from equation for ideal transition curve taken for y-coordinate.
Lemniscate curve————————————->the path actually traced by an automobile turning freely.{ Lemniscate curve of transition throughout is introduced to connect two parallel roads, the maximum polar angle of the curve is 30° and Setting out of Lemniscate transition curves is done with polar deflection angles.}
Froude’s transition—————————————>length of curve measured on tangent with the first term only taken into account for both x and y coordinates from equation for ideal transition curve.
True or clothoid spiral———————————->length of curve measured on the curve with at atleast two terms adopted for x and y coordinates from equation for ideal transition curve.

Answer 2

A track transition curve, or spiral easement, is a mathematically-calculated curve on a section of highway, or railroad track, in which a straight section changes ...
