The Northeast Regional Travel Demand Model (TDM) covers all of Outagamie, Winnebago, Calumet, Fond du Lac, Sheboygan, Manitowoc, Brown, Kewaunee, Door Counties and part of Oconto, Shawano, Waupaca, Dodge, Washington Counties and portions of Waupaca County. The TDM includes vehicle, single-unit and combination trucks and a transit component that includes 4 fixed route systems.
The Travel Demand Model consists of the following:
o Employment (service, retail & “other” ((Wholesale Trade, Construction, Transportation etc-(think truck trips))
o School Enrollment
o Regional Shopping Centers
o Passenger Airports
The Northeast TDM uses a trip based four-step gravity model consisting of:
o Number and type of trips each TAZ produces or attracts is calculated, truck trips are generated based on the FHWA Quick Response Freight Manual variables.
o Trips are distributed by TAZ from origins to destinations.
o Assigns trips to cars or public transit
o Trips are assigned to highway network, using the shortest time. Once a roadway becomes congested with speeds reduced, the next shortest time is used.
The model estimates trips by calculating the number and types of trips traveling between transportation analysis zones across the transportation network. The model uses base year data from 2010, with a forecast year of 2045. Straight-line intermediate years have been developed for the model for conformity analysis in the Sheboygan non-attainment area. Within each analysis year, the Northeast TDM estimates traffic movement for four distinct time periods, AM, midday, PM and evening. The TDM is used to analyze the composition of traffic, purpose of travel, peak hour usage, and origin-destination linkages. This allows for explicit analysis of future travel behavior along major transportation corridors. The TDM is used for forecasting traffic volumes and patterns for corridor studies and congested roadways for the Metropolitan Transportation Plans (MTP).
