hi students!!!

this is the notes of Geometrical design in transportation engineering which consist SUperelevation, curves, widening etc

contents:--

• guideline and design of superelevation
  
• maximum and minimum superelevation
  
• attainment of superelevation
  
• radius of horizontal curve
  
• extra widening, mechanical widening, physiological widening
  
• horizontal transition curves
  
• types of transition curves
  
• length of transition curves
  
• rate of change of centrifugal accelaration
  
• setback distance
  
• curve resistance
  
• and some problems
