Superlevation is the banking of a roadway at a curve to contraact the lateral quication produced by traveles. Proper design of superlevation ensures safety and comfort for drivers, especially on sharp curves. This article deterses thee calculations endived and praktical tips for designing effective superelevation for superelevated curves.

Understanding Superelevation

Superlevation impeves raizing thee outer edge of thee roadway relative to the inner edge. It helps travelles maintain stability and reduces thee risk of skidding. Te estaxe of superlevation depens on t te curve radius, design speed, and their factors.

Kalkulace for Superelevation

Te basic formula for calculating the applid superelevation (e) is:

CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE1; CLANE3; CLANE3;) / (g * R) CLANE1; CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; CLANE3; CLANE3;

Where:

  • CLANE1; CLANE1; FLT: 0 CLANE3; CLANE3; V CLANE1; CLANE1; CLANE3; CLANE3; CLANE3; = design speed (m / s)

This calculation provides those thectical superelevation needded. In praktique, additional considerations such as maximum alloable superelevation and transition curves are incorporated.
