2011 MTP Travel Forecasting Documentation
Federal transportation planning regulations require documentation of the input assumptions and methods used for developing travel forecasts [23 CFR 450.316].  The documentation of the 2013 MTP Update, Horizon 2040 (in development), includes an (1) inventory of the current state of transportation in the planning area, (2) key planning assumptions used in developing forecasts, and (3) descriptions of the methods used to develop forecasts of future travel demand.  The documentation and corresponding appendices are located here:

Documentation for the latest updates to the regional travel demand model is available here:

2010 Travel Demand Forecasting

The 2005 Regional Travel Survey is the basis for many of the model factors. For more information on the land use development process, click here.

Model Data
As a service to SRTC partner agencies and the consulting firms they work with, SRTC provides transportation modeling data in an effort to ensure regionally consistent transportation studies in Spokane County.  That data can include networks, operating characteristics, households and employment by traffic analysis zones, and modeling assumptions. This information is provided free of charge, although there may be minimal costs associated in reproducing this information.

In order to receive transportation modeling data, please fill out this Model Data Request Form and email it to
