Calculating the curve – The Municipal

Critical speed is determined based on how sharp the curve is how much bank is in the roadway and the road surface's "stickiness " or coefficient of friction By measuring these three factors and plugging them into a formula the critical speed of a curve can be calculated Let's examine a curve in the road that has a radius of 200 feet
