Working to finish pulling / reconciling various contributions to develop
Will release multizone and wait on estimation until everything done and QA/QC'd in Jan
I checked out Clint's PR to my fork and then resolved conflicts and merged to ActivitySim since I don't have write access to Clint's fork
Newman and Doyle to work on estimation branch moving forward
ARC update
ARC not using the coefficient files - just a dummy file for now since that's easier for translating CT-RAMP UECs
Would be good to note things to watch out for in release notes
Updated to pandas 1.1.0 required
Dynamic chunking for ARC dropped runtimes from 16 hours to 8 hours!
Clint to share his activitysim presentation to ARC with the team at a later time
Clint tried the scheduling model improvement of just O,D pairs and not O,D,duration but didn't help
We still think it would be good to de-duplicate within chunks the logsums alternatives to improve runtimes
Doyle to work on performance tuning after estimation work
TVPB validation
Fixed a few more drive transit expressions in the Marin examples and results looking good
Trying to balance directly translating the existing expressions versus cleaning up the example so its easier on someone who downloads our example and wants to learn from it
For distributed examples, we may want to take out all the calibration/adjustment type stuff specific to regions since it adds a lot of extra stuff to the expressions to understand and support, makes it more difficult to use for a new region, and highlights the dark corners of model calibration/fit
Basically, our examples should strive to be more examples and less a specific implementation for a specific region
I'll move the auto sufficiency expressions to the tour mode choice pre-processor to make it easier to understand
Its probably three phases to creating good examples - 1) Marin TM2 --> 2) ActivitySim software testing --> 3) ActivitySim example for distribution
Licensing / copyright
Bench contract delayed due to inconsistent project history with licensing / copyright
There's conflicting license and copyrights in all previous contracts and GitHub resources
At issue is a work for hire clause and copyright, especially related to UrbanSim and the time period of the acquisition by Autodesk
RSG, WSP, and CS happy to do whatever the consortium/AMPO wants
Joe talk with AMPO attorney and may assert copyright back to the beginning of all contracts
Guy to help Joe with understanding old discussions related to the topic
Discuss estimation integration progress
Our example model can produce some synthetic travel diaries that are not consistent with the CDAP patterns
Not many, but a few, and for example two preschoolers going shopping
So this makes testing estimation a bit difficult because our data set is a bit funny
CDAP model is already pretty complex so let's not add more to it
Basically it seems there is some leakage in the downstream logic
Would be good to know how rare this is?
It is the users responsibility to supply a well formed survey for estimation
Would be good to be very explicit in the docs about the survey data expectations, which of course vary by the submodels/spines
I'll create an issue so we don't forget
Let's talk with Doyle next time we chat
We could add re-simulating a household like DaySim does, if the household is determined to have bad results or can't complete
