Project Meeting 2021.04.13 - ActivitySim/activitysim GitHub Wiki
Issues review
Discuss updated transit pass ownership model
Joel reviewed the bay area data
Clipper card is not really a pass so can we remove it?
How does each type of pass relate to the fare discount per trip?
Average subsidized fare is about 50% but this is very region specific
Revised model alternatives - subsidized pass, not subsidized pass, no pass
In application, the pass would be segmented by markets and each can have a separate fare discount amount
Can we try to figure out what they actually paid in the data for each trip? / figure out the discount
Maybe the outcome isn't discrete....can we make it continuous?
There's a lot of variety in this topic across regions and within and the data is incomplete
The HH survey is not enough data granularity
ARC OBS has many many pass types
What is the out of pocket cost for each actual trip? It's difficult to say
How to calculate the discount, that's the key
SEMCOG doesn't have the data to reestimate this model
Next steps, reestimate without Clipper card
Iterate on design with team, post design into a Google doc
Hold on implementation for now
Model will influence auto ownership and mode choice
Release just about ready to go, still need to document pre-sampling feature and settings file inheritance, #411
Task 7 usability issues plan:
Improve RAM/chunking settings, #406
Switch from chunk_size parameter to available_memory parameter (say 56GB) and let ActivitySim figure out the appropriate chunk_size given the number of processors specified
Print info about no alternative found, #404
Turn off restarting if desired, #405
Discuss ActivitySim related presentations at the TRB Planning Applications and/or AMPO Annual conference ?
