Roadway superelevation design
WebAug 10, 2015 · However, with the Roadway Designer superelevation functionality, there is no limitation on the number of control lines or pivot points. Using superelevation control lines along with the normal template constraints on the points allows you to get exactly the desired results. Superelevation control lines are grouped into super sections. WebThe vertical alignment will only include calculations for the centerline of the roadway. Superelevation considerations will be based on the centerline profile. Based on the design speed, select a K value from the appropriate vertical curve chart (crest or sag) and calculate a minimum curve length.
