TransLink recently (as of 2 weeks ago) started working with @dhensle on developing and implementing a park and ride module for our ActivitySim model. We have a very tight development timeline and we are looking to complete implementation by end of August. We are hoping to get some feedback and to request code review from the consortium on the park and ride module code changes we will make. We are planning on submitting our code in early September.

If you have any questions about this, feel free to ask myself or @dhensle about it. We hope our work can be a meaningful contribution to the consortium.

I sent an email to remind/inform the wider ActivitySim population the engineering will not meet today, but MWCOG's email decided it was spam and bounced it back to me. So this is your notification instead. 😉

@bwentl: do you have a GitHub Issue that describes the proposed Park and Ride approach that you are implementing for the @ActivitySim/product team can have a look at? If not, can you please create one?

Re: Estimation Enhancements, John is aiming to get his comments in by early next week (starting 8/11).

Otherwise, I need to open an issue regarding YAML files with spurious settings.

My update- I have been helping to test the expression profiling pull request.

ActivitySim/activitysim#936

I am really looking forward to hearing more about the park and ride work.

@bwentl: do you have a GitHub Issue that describes the proposed Park and Ride approach that you are implementing for the @ActivitySim/product team can have a look at? If not, can you please create one?

@DavidOry Issue for PnR methodology is posted here: ActivitySim/activitysim#965

@andkay or @johnpgliebe could you please check if the bug reported in ActivitySim/activitysim#595 still exists?
