Improve Joint Tour Participation Model

1

Joint tour frequency model generates household joint tours. Then joint tour composition model determines if a joint tour is: 1 = Adult-only, 2 = Children-only, 3 = Mixed. Lastly, joint...

larch conflicts with skims.omx

2

We have packaged some python files for convenience. And when packaging estimation codes together, there are conflicts if we import larch. The '_read_skims_from_omx' part fails. The 'skims.omx' contains 116 skim...

The psutil library cannot measure USS values greater than 2^37 bytes on Windows. That's about 128GB. The limitation is hard-coded [here](https://github.com/giampaolo/psutil/blob/4f053312934cdca739c3fefe4ada8a4f2d096bdd/psutil/_psutil_windows.c#L523). This limitation probably doesn't matter in practice -- if...

Clean up documentation of the base MTC example

1

There is documentation for the inputs of the demo "MTC" model here: https://activitysim.github.io/activitysim/examples.html#inputs But it isn't formatted well and it is hard to read and follow. These docs could benefit...

Documentation missing 'access_dist_transit' landuse field

4

The field 'access_dist_transit', if it exists, is used for the walk access/egress component for transit in tour mode choice. If it does not exist, the model uses a constant. The...

I suggest we follow the "new" (from 18 months ago) [default branch naming scheme at GitHub](https://www.zdnet.com/article/github-to-replace-master-with-alternative-term-to-avoid-slavery-references/), and swap out the "master" name for "main". This change should have minimal impact...

One comment I will make: I feel as though the way the aggregation maps are currently defined isn't super user-friendly. For example, the major access trip mode in the MTC...

Bitwidth expectations

4

The current ActivitySim implementation generally does not explicitly define bitwidths for numerical values, but instead allows numpy to self-select the numerical precision. This generally results in double precision floats almost...

The user cannot add columns that are calculated in the pre-processor to the final output tables. (Some models do have optional "annotate" steps to populate columns, but not all. They...

In #539 we made it so kwargs could pass through for location choice model estimation. The same treatment should be applied to other models as well (e.g. auto_ownership, etc.)
