A/B Street

A/B Street is open-source transport planning and traffic simulation software with its simulation, map model, and application code organized as Rust crates. It lets users edit streets and intersections and explore changes for walking, cycling, and public transit using OpenStreetMap data.

The original simulation is available for desktop systems and the web. The broader project has also branched into separate active-travel planning tools; this listing links to the original A/B Street repository.
