Where to Find the MovSim Sources and Traffic Flow Books Linked from traffic-simulation.de

The traffic-simulation.de onramp page points to three offline resources: the MovSim source code on GitHub, the English-language book Traffic Flow Dynamics, and the German-language book Verkehrsdynamik. Use the GitHub repository if you want to read, run, or extend the simulation code; use the books if you want the theory behind the car-following, lane-changing, and ramp-metering behavior shown in the browser.

The GitHub source (MovSim)

The page lists its offline sources as "sources at GitHub" under the MovSim project. This is the practical entry point if you want to work with the model outside the browser.

What you can expect to do with it:

• Inspect how the simulation is implemented rather than only watching the canvas output.
• Run the model locally, which matters if you want repeatable runs or longer experiments than a browser session.
• Extend or modify behavior — for example the car-following and lane-changing rules that the onramp page exposes as adjustable parameters.

A reasonable workflow:

1. Open the MovSim repository on GitHub from the link on the site.
2. Read the repository's own build and run instructions — these are maintained with the code, so treat them as authoritative over anything summarized elsewhere.
3. Build and run a small scenario first to confirm your setup works before changing parameters or code.
4. Compare your local output against the browser simulation to check you have reproduced the same model.

The main friction point is that a research simulation repository assumes some familiarity with its build tooling and language. If you only want to understand the concepts, the books below are the faster route.

The two books

The site references two books, which cover the same modeling ground in different languages:

Both are attributed to Martin Treiber, who is also credited on the simulation page, so the books and the browser model come from the same modeling tradition. That makes them a coherent pairing: the simulation is a way to see the models in action, and the books explain why the models are built the way they are.

Which one to pick

• You want to modify or embed the simulation: start with the MovSim GitHub sources.
• You want to understand the parameters on the onramp page (car-following behavior, lane-changing behavior, and the flow controls): the books give the underlying model definitions.
• You want both: read the relevant book chapter first, then check the corresponding implementation in the repository — the mapping between equation and code is usually clearer in that order.

One caveat: the page itself does not state licensing, version, or supported platforms for the sources, and it does not give publication details for the books. Check the repository and the book listings directly for current information before relying on either for a project.
