The mission of the ActivitySim project is to create and maintain advanced, open-source, activity-based travel behavior modeling software based on best software development practices for distribution at no charge to the public.

The button below will take you to ActivitySim’s Github page. This page captures ongoing work and development plus decisions and conversations related to the development of ActivitySim. The GitHub issues and milestones are commonly tied to development work and are linked when possible to programmed work efforts. You can also check out our industry presentations and affiliated packages.

ActivitySim is already being put to work across the U.S. and around the world as a better way to model travel behavior. Click the button below to check out some examples. And if you’re an ActivitySim user, we’d love to hear what you’re doing with it. Contact us!
