Supereation involves raising the outer edge of a curve relative to te inner edge. This banking controlls the lateral acceleration experirected by by y vehibles, helping them maintain stability at higher speeds.
Methods for Designing Superelevation
Designing superelevation typically involves calcating thee appropriate banking angle based on thee curve radius, design speed, and tell factors. Common methods included:
