Project Meeting 2021.12.23 - ActivitySim/activitysim GitHub Wiki

Agenda

• Vehicle type model update

  • Gathered additional data for use in estimation:
    • EPA published fuel efficiency for vehicles
    • Average vehicle cost
    • Number of charging stations (region wide parameter)
    • Much of the data could be maintained at a national level, sharing responsibility for updating among all of the members
  • Have started performing estimations, but not all the results are in yet
  • Still need to estimate a model that determines which vehicle gets used in the household (will use the NHTS data transformed into tours)
  • More work needed to understand the effect of costs: purchase price, incentives, depreciation, operating costs, etc.
  • Good to keep in mind that there are two different model options. Option 4 (predicting all dimensions of vehicle type) is being estimated currently, and then option 2 will drop all of the coefficients that no longer apply.

• Proposal receipts and schedule

  • Proposals have been received
  • Agency partners are invited to participate in proposal evaluations
