SIDRA API

The SIDRA API is a COM-visible .NET 8 library that lets external applications drive SIDRA Intersection: open and save projects, configure intersections, run analyses, and read results back. The API surface lives in the SIDRASolutions.SI.API namespace and is consumed from C#, VB.NET, Python (via pywin32), PowerShell, or any other COM-capable host.

I want to...

• Get started

  Install the API, reference the type library, open your first project.

• Browse the API reference

  Every public type, member, parameter, and return value.

• See code samples

  Minimal working programs in C#, VB.NET, Python, and PowerShell.

• Understand the object model

  How ISIAPI, Project, Site, Intersection, Leg, and the lane hierarchy fit together.

Versions

This documentation is versioned per API release. Use the version selector in the top bar to switch between releases — match it to your installed build of SIDRA Intersection. The site always opens on the latest release; older versions stay available and frozen.
