Project Meeting 2021.04.08 - ActivitySim/activitysim GitHub Wiki
Task 1 Project Management (milestone)
- Working on documentation/examples/tidying-up for upcoming release v0.99
- Examples all downloadable, including SANDAG
- Getting started, examples, notebooks, submodels sections updated, still working on core, test system, estimation
- PopulationSim documentation updated
Task 2 Complete Estimation Mode (milestone)
- See task 1
Task 3 Telecommute Model in Cooperation with SEMCOG (milestone)
- Discussed Telecommute google doc here
- I'll address the comments, which are all straightforward except for the what-if analysis need
- We discussed the what-if analysis in detail and agreed to build an iterative procedure into the model that compares the work from home share to a target and iterates by adjusting a coefficient until the target is met (or max iterations is met)
- This doesn't need to be a systematic generic auto-calibration routine for everything activitysim; rather it can be just for this model
- It's similar to shadow pricing but it works at the global level instead of zone level
- Let's not let the perfect get in the way of good enough
- I'll work on a little mockup/design for further discussion and update the memo
- Need to discuss (but not implement) the DaySim in/out commuters feature here as well since it relates to telecommuters
Task 4 Transit Pass Ownership Model in Cooperation with SEMCOG (milestone)
- Joel to report back on data analysis on Tuesday
Task 5 Performance Enhancements (milestone)
- See task 1
Task 6 Prototype multiple models test system (milestone)
- See task 1
Task 7 Input checking and error handling and pipeline improvements (milestone)
- Discussed potential improvements list
- Votes below
- Since the chunking improvement is a big lift and we've heard a lot of feedback related to it, we're going to do that
- We can also do the most popular one - print info on no alt found - since it's small
- We're tentatively going to do 407, 406, 405, and 411
- Let's think it through a bit more and discuss next week
- Let's create an issue to improve logging when users get high trip fail rate for trip destination, like PSRC is experiencing. This is new issue #416.
| feature | issue | votes | LOE estimate |
|---|---|---|---|
| when no alt found print expressions turned off | #404 | 7 | easy |
| chunking | #406 | 6 | modest to involved |
| input checking | #401 | 5 | wide open |
| parsing configs | #402 | 4 | wide open |
| turn off restart | #405 | 2 | easy |
| expression timing | #412 | 2 | |
| long trace file names | #409 | 1 | |
| better inheritance file documentation | #411 | I'll do as part of the documentation updates |
Task 8 Maintenance and Support (milestone)
