The following data is given for a horizontal highwaycurve having 2 lanes with Lane width of 3.65 m each: Ruling designspeed is 110kmph, Allowable rate of change of circular acceleration= 0.5 to 0.8. Allowable rate of introduction of super-elevation = 1in 144, Take maximum allowable superelevation and lateralfrictional co-efficient is 0.15.
Calculate the length of a transition curve for following cases.
Rate of change of centrifugal acceleration(C).
Rate of introduction of super-elevation.
Using empirical equations for plain and mountainousterrain.
