Join me in exploring the intricacies of designing dual carriageway super elevation in Civil 3D. Learn how to apply specific formulae and criteria for optimal results.

The video delves into the design criteria tailored for Saudi Arabia, including factors like transition, runoff length, and minimum radius table.
It references the Saudi Arabian highway design manual, which provides comprehensive tables for setting criteria and an equation for verifying length.
The calculation of super elevation rate and relevant examples are thoroughly discussed, with specific focus on Oman and Saudi Arabia standards.
The derived take of 7.3 is determined based on factors like the harassment factor, gradient, and minimum run length. The video also addresses the minimum length and design criteria for the wide part transition, presenting values of 14.6 and 107 for different aspects of the design. Additionally, it covers the alignment and design criteria of the wide part transition, as well as the process of creating super elevation, including handling errors and performing manual calculation checks.
The video concludes with insights on selecting and confirming design criteria for dual carriageway, an explanation of station and transition calculation, and the verification of design criteria according to Saudi standards using tools like Excel.
