Research Project
Grand Forks / East Grand Forks MPO 2010 Regional Travel Model Update

Completed: Apr 2013

The Advanced Traffic Analysis Center (ATAC) at North Dakota State University is responsible for updating and maintaining the Grand Forks / East Grand Forks Metropolitan Travel Demand Model (TDM). The model is updated every five years. The model is developed in Citilabs Cube Voyager software and comprises four steps including trip generation, trip distribution, modal split and trip assignment. The model was calibrated to Base 2010 Conditions with trip rates from the Fargo / Moorhead area used for trip generations. The model results were validated against 2010 base year data including trip length frequency distributions, vehicle miles traveled, screenline counts, trip generation totals, and a modeled versus counted traffic volumes. The model was able to replicate the base year 2010 data within acceptable industrial limits.

Keywords: travel demand model, trip generation, trip distribution, modal split, trip assignment, validation, and calibration
