The trip-based model is a system of mathematical and statistical processes that estimates daily travel patterns within the Puget Sound region.
How Does the Trip-Based Travel Model Work?
For every household in the region, the model estimates how many trips are made each day, where they go, what time of day they travel, which modes they use, and which routes they follow. The relationships that are estimated for the 2014 base year are combined with future population, employment, and transportation infrastructure growth assumptions to produce future travel forecasts. The future travel forecasts are then analyzed to inform regional transportation studies and plans. The model uses Inro’s Emme software and is built entirely in the Emme macro language.
