Project Meeting 2021.04.15 - ActivitySim/activitysim GitHub Wiki
Task 1 Project Management (milestone )
Partners call after this
Bench IRFPs planned for next week
Still working on documentation/examples/tidying-up for upcoming release v0.99
Improved handling of long filenames, #409
PSRC fixed high trip fail rate - was related to bad land use input data
We'll plan a workshop at the AMPO conference in October
And also maybe a workshop at the technical symposium in May of next year
A 2 hour workshop at the AMPO conference should be good
@Joe, Caitlin, Ben setup a separate call to discuss
Chattanooga also interested in ActivitySim
Task 2 Complete Estimation Mode (milestone )
Task 3 Telecommute Model in Cooperation with SEMCOG (milestone )
Task 4 Transit Pass Ownership Model in Cooperation with SEMCOG (milestone )
Joel working on revisions based on comments
MTC looking into employment data and other sources but this exercise has identified a need for fare subsidy information in future surveys
Folks to review the latest design emails
How might this relate to MaaS options?
Remember discounts (e.g. age) and subsidies (e.g. employer) are different things
Maybe make two separate models?
It would be good to inventory more use cases for this model? Please share ideas/needs if you have them
Passes by income, age, student, employer, for equity reasons, etc.
Can we add an override percent feature similar to telecommute model?
Task 5 Performance Enhancements (milestone )
Task 6 Prototype multiple models test system (milestone )
Task 7 Input checking and error handling and pipeline improvements (milestone )
Task 7 usability issues plan:
Improve RAM/chunking settings #406
Switch from chunk_size parameter to available_memory parameter (say 56GB of 64GB available on the machine) and let ActivitySim figure out the appropriate chunk_size given the number of processors specified
And save the calculated settings to disk so ActivitySim can re-use it next time to save even a little more time. This assumes the same basic inputs, machine config, etc.
Print info about no alternative found, #404
Turn off restarting if desired, #405
Jeff to start on this next week
Task 8 Maintenance and Support (milestone )
