if N is the algebraic difference of grades, S is the headlight sight distance in metres, then the transmission length of a valley curve (following standard codes) should roughly be equal to
The design speed of a highway is 80 km per hour. Assuming other data as per IRC recommendations, which one of the following is the approximate adopted lag distance?
Consider the following steps involved in the design of super elevation in practice as recommended by IRC :
1. Calculation of the allowable speed for maximum ‘e’ and design value of T
2. Calculation of the super elevation for 75% of the design speed
3. Calculation of the value of ‘e’ and recheck
4. Calculation of the value of ‘f and recheck
The correct sequence of these steps is
