Abstract
The Fargo Moorhead MPO Travel Demand Model (TDM) is updated every five years to replicate new data and the advancements in the state-of-the-art in transportation modeling methods and techniques. The current model update reflects 2015 base year data. The four-step TDM include trip generations, trip distributions, modal split and trip assignment. The model update process involves the calibration of model input parameters and validation of model output with ground truths.
For the 2015 base year model, several updates were made to reflect the availability of new and improved data, new and advanced methods in modeling software and the inclusion of long-haul freight movements as part of the model. New data that was used for 2015 model update included: Origin Destination Data (Obtained from Airsage), the traffic analysis tool data, incorporation of truck counts and Freight Analysis Framework (FAF) data to model freights.
