Wisconsin Statewide Model

David Cipra from the Wisconsin DOT joined us via video conference. He gave a presentation of Wisconsin’s experience in the development of a statewide model along with an overview of the model, and it’s use for state and local road forecasts. The centralized forecasting function utilizes a 1,800+ zone, statewide network with 12 nested MPO travel demand models, 6,000 regressions based on historical AADT’s, and indices for “expected growth and development” along each major segment in the state model.

Metropolitan Council Experience in Using Census Bureau LEHD to Generate Journey to Work Flow Data

Bob Paddock from the Metropolitan Council gave a presentation and his experience using LEHD data. He expects to be able to make comparisons between CTPP, TBI and LEHD data and present his findings at our next meeting.
