Thanks Ben for adding this, hence allowing us to potentially explore the option of adding a built-in, self-calibration routine in mode choice calibration, which could systematically adjust constants to match...

Thanks Jeff for bringing this up to our attention. Indeed the ARC ActivitySim example is merely a prototype model application at this point in time. That said, we at ARC...

Thanks Jeff for bringing this up to our attention. I can confirm that within our ARC trip scheduling choice (see attached, rows 81-82) there is a calibration parameter of -100...

One more note: The way probabilities are resolved in UECs, we use -999 to signal a condition that makes an alternative unavailable. I’ve also seen -99 or other similar large...

Thanks @mnbina for posting this, and for an additional reference, see https://stackoverflow.com/questions/43440821/the-real-difference-between-float32-and-float64

As for file name length, ARC is a little more hesitant with this one. The length requirement was originally set because of the constraints of binary itself (255) and consistent...

Indeed, the ARC ABM functions at a temporal resolution of 30 minutes, so in half-hour increments. Although activities are scheduled with a 30-minute resolution, level-of-service matrices are only created for...

Thanks everyone for contributing to this very relevant WFH topic within the context of our post-pandemic regional activity-based travel demand forecasting models, including ActivitySim of course. I would also simply...

Chunking is an issue. Running ActivitySim without chunking is ideal. If you have enough memory to load everything into memory without chunking, this might be the fastest way to run...

For additional contextual info and background on ARC's trip scheduling approach, this takes place as part of our intermediate stop duration model that we developed at ARC a few years...
