Regional Travel Demand Model

The Benton-Franklin Council of Governments develops a Regional Travel Demand Model to estimate average weekday and peak hour demand for the transportation system for the Tri-Cities Metropolitan Planning Area. The model is an essential analytical tool for both metropolitan and regional transportation planning. It is used to develop multiple travel-demand scenarios.

The updated model will be sensitive to regional land use, employment, population characteristics, transit and non-motorized travel. New Traffic Analysis Zones (TAZs) were delineated which will allow for much finer detail in modeling travel.

Traffic Analysis Zones (TAZs)
The updated model has 1,065 TAZs, up from the 242 that were in the 2010 model. TAZs were delineated using various legal boundaries and built/geographic barriers. This included water ways, railroad tracks, transportation network and census. On a few occasions, TAZs include more than one jurisdiction.

Base Year Population was derived using the Washington State Department of Office and Financial Management (OFM) Small Area Estimate Program (SAEP). OFM provided the following 2015 estimates for each TAZ:

  • Total Population
  • Household Population
  • Total Housing Units

Further information about the Small Area Estimate Program can be found in their User Guide.

BFCG utilized multiple data sources and verification for collecting base year employment information. The model uses the following employment categories:

  • Agriculture
  • Mining
  • Construction
  • Manufacturing
  • Wholesale
  • Retail
  • Transportation & Warehousing
  • Service
  • Finance & Insurance, Real Estate
  • Education
  • Retail
  • Government

Regional Traffic Count Program

The Benton-Franklin Council of Governments relies on traffic counts from member jurisdictions for tracking vehicle and classification count data to analyze volumes and freight movement over time. In Benton & Franklin counties traffic counts are important for use in the Tri-City Area Traffic Model, Local comprehensive plans and economic development by private sector developers, real estate professionals and property owners. Local jurisdictions rely on Average Daily Traffic (ADT) when making road improvements to determine traffic closures, detours and staging. Traffic count data is useful for determining future roadway and capacity needs and also as input to assist in establishing Federal Functional Classifications.

Traffic count data will be important as part of the metrics used to measure performance targets. Performance measures will play a direct role in identifying transportation investments. in the application process for state transportation funding programs such as the Freight Mobility Strategic Investment Board (FMSIB), Transportation Investment Board (TIB) and County Road Assessment Board (CRAB).

Count specifications included a 72-hour (Tuesday, Wednesday & Thursday) bi-directional counts at approximately 630 sites in Benton & Franklin Counties. The counts would collect the following data: Vehicle Volume, Vehicle Classification & Vehicle Speed by 15 minute intervals with a grand total for each site.
