🧵 4/? The fundamental assumption, or if you like, "science" behind this approach is that there is some implicit and finite number of privately-owned vehicles that will arrive, dwell, and depart a location based solely on a single variable (e.g., gross floor area, # of beds/seats), and land use.
This is not science, it is middle school math. We are doing straight line regression on a two-variable problem. We've been doing it so long it's the "standard of care" nobody will testify against.
