" 1't/E'd e e Mr. Carl Ohm Mr. Jon Olson July 1, 1994 Page 2 Forecast Methodology, Network Development, and Trip Table Development The traffic forecasts were developed using the Metropolitan Council regional travel model that operates on the transportation planning software, TRANPLAN. Base networks and base trip tables were forwarded by the Metropolitan Council to BRW, Inc. The base networks and base trip tables were: 1) Year 1990 existing network and trip table, also included in the network flle were actual ground counts by link. The ground count data was used to adjust the forecast model volumes. 2) Year 2015 base network and trip table. The network file contained all E+C roadway improvements to the street system in Anoka County. The roadway improvements were checked for accuracy with staff from Anoka County. The trip table file contained vehicle trips forecast using land use forecasts provided by the Metropolitan Council. An additional network was developed for the E+C+P roadway improvements with help from Anoka County staff. An expanded MUSA trip table was developed with input from staff at the Cities of Andover and Ramsey. Meetings with planning staff at Andover and Ramsey, identified areas outside the current MUSA line where potential future housing developments would occur and the number of houses that would potentially be built within those areas. The specified geographic areas were converted to the traffic analysis zone (TAZ) level and a fratar model was used to increase vehicle trips from and to those TAZs where additional housing would potentially be constructed within the Cities of Andover and Ramsey. The following increases in vehicle trips were applied to calculate an Expanded MUSA trip table. 92:11 Vb, 01 ~n~
