ActivitySim
An Open Platform for Activity-Based Travel Modeling
**Describe the bug** When running a partial model run using `resume_after` with multiprocessing enabled, and reusing the pipeline files of a completed model run, the `write_data_dictionary` step fails with the...
Existing tests primarily focus on "integration" testing, i.e. running the entire modeling system as an integrated unit, and checking if the models run correctly end-to-end, giving expected results. This is...
Shifting ActivitySim’s internals from **Pandas** to **Polars** could have some very tangible benefits, because Polars is designed for performance and scalability in ways that align nicely with the demands of...
Moving a platform like **ActivitySim** from **Pandas** to **JAX** would be a pretty big architectural shift, but it could unlock some unique advantages for large-scale activity-based modeling. ## Advantages ---...
Shifting ActivitySim’s core functionality to **Rust** could address some of the scalability and maintainability challenges of Python while keeping the user-facing API familiar. Here’s why this could be a good...
Using **Awkward Array** in a future version of **ActivitySim** could provide meaningful benefits because ActivitySim has to manipulate very large, hierarchical, and heterogeneous datasets of agents, tours, trips, and households....
**Is your feature request related to a problem? Please describe.** Development of a GUI for ActivitySim. The concept of “a GUI” for a model is extremely broad and can mean...
**Describe the bug** If you change a parameter in the SPEC file, LARCH will correctly estimate the new coefficients. However, when you save the estimated parameters, the revised coefficients file...
This issue is partly a duplicate of issue #688, but I was not able to find a reasonable way to address it. When running the MWCOG model (which uses ActivitySim...
