This PR brings in model specifications from SANDAG's ABM3 production model, version v15.2.1. Changes were manually reviewed to make sure they do not overwrite any existing Sharrow-related changes that have been added in this repo but not in the SANDAG's production version.

Detailed changes include:

  • Updated model constants values.
  • Updated coefficients and constants in various models.
  • Corrected a mixed party spec error in joint_tour_frequency_composition.csv.
  • Introduced 3 segments in parking_location_choice.csv.
  • Segmented auto cost factors by occupancy.

This PR was auto-closed because pandas2 branch was merged and deleted. It cannot be re-opened. I will create a new PR targeting main.
