What is Minimum Length of Vertical Curves about?

This document provides four examples of calculating minimum vertical curve lengths for road design. Example 1 calculates a minimum length of 452.79m for a 100 km/h speed curve connecting grades of +2.60% and -2.40%. Example 2 finds a minimum length of 216.41m for an 80 km/h curve between -2.30% and +4.80% grades. Example 3 determines the chainage and elevation of a low point on a 400m curve between -2.00% and +4.00% grades. Example 4 solves for a 1007.21m length to make the high point of a curve align with
