WebAn Euler spiral is a curve whose curvature changes linearly with its curve length (the curvature of a circular curve is equal to the reciprocal of the radius). Euler spirals are also commonly referred to as spiros, clothoids, or Cornu spirals.. Euler spirals have applications to diffraction computations. They are also widely used in railway and highway engineering … WebSpiral is a type of transition curve which is recommended by IRC as ideal transition curve because of its smooth introduction of centrifugal acceleration.
