As the lead developer for both ActivitySim and PopulationSim, we're thrilled to announce some recent updates. These updates have made the open-source platform easier to use, faster, and better at forecasting travel. The latest ActivitySim updates included several significant RSG-developed contributions:
PopulationSim updates included adding support for parallelization (i.e., multiprocessing) to significantly reduce runtimes.
ActivitySim is a state-of-the-practice activity-based modeling platform that is always improving, and RSG and ActivitySim consortium members are currently planning more updates. These include support for transit pass ownership modeling and improved methods for configuring and running the model with available machine memory—to make configuration easier and reduce runtimes.
