Base networks and base trip tables were forwarded by the <br />Metropolitan Council to BRW, Inc. <br />The regional travel model assumes growth (in population, households, and <br />employment) for all cities and towns within Anoka County as well as in the <br />metropolitan area. Therefore, growth is assumed not only in Andover and <br />Ramsey but in adjacent communities. <br />The base networks and base trip tables were: <br />1) Year 1990 existing network and trip table. Actual ground counts by link <br />were also included in the network file. The ground count data was used <br />to adjust the forecast model volumes. <br />2) Year 2005 trip table and Year 2000 base network. The Year 2000 network <br />file was updated to include all Year 2005 E±C roadway improvements to <br />the street syste:n in Anoka County. The Year 2005 trip table file <br />contained vehicle trips projected using land use forecasts provided by <br />the Metropolitan Council. <br />
