MATSim

MATSim stands for Multi-Agent Transport Simulation. It is a project that came in part out of TRANSIMS; it decomposes traffic assignment into iterating between route choice and network loading, and then integrates additional choice dimensions, such as mode or departure time choice, into that loop. The iterations follow a co-evolutionary approach. That is, the synthetic travellers (or "agents") from time to time come up with new alternatives (= new plans), try them out on the network loading (called "mobility simulation"), and obtain a score/utility for these new alternatives. If they do not come up with new alternatives, each synthetic person selects between its existing alternatives according to the score/utility.

• The MATSim example project (opens new window) is meant as the general entry point. It is possible to download the contents as a zipfile, unzip it, generate a Java "jar" file, and run it; only a Java Runtime Environment (JRE) needs to be installed for this. In general, one would probably rather github-fork the project, clone the fork, and run it out of an IDE (e.g. Intellij or Eclipse).
