H/S'd e e Mr. Carl Ohm Mr. Jon Olson July 1, 1994 Page 7 . Screenlines at the Mississippi River bridges 19) TH 169 Bridge 20) TH 610 Bridge In order to reflect the future traffic volumes in the study area more realistically, the plus or minus difference between the 1990 ground and 1990 modeled volumes were used to adjust the Year 2015 modeled volumes. In most cases, as can be seen in Table 1, the 1990 ground and 1990 modeled volumes are similar. Development of PM Design Hour Directional Traffic Volumes Historical traffic volume data from Anoka County and the Minnesota Department of Transportation was used in developing PM design hour directional volumes at the above listed screenline locations. The factors used for calculating ADT volumes to PM design hour directional volumes are listed below. 1) TH 169 --15.2% design hour factor (DHF), 65% westbound - 35% eastbound . 2) TH 47 - 9.77% DHF, 30% southbound - 70% northbound 3) 7th Avenue - 8.66% DHF, 55% southbound - 45% northbound 4) Round Lake Boulevard - 9.82% DHF, 46% southbound - 54% northbound 5) m 10/47 -15.2% OHF, 60% westbound - 40% eastbound 6) Coon Creek Boulevard - 11.81% DHF, 31% southbound - 69% northbound 7) Hanson Boulevard - 9.97% DHF, 32% southbound - 68% northbound 8) TH 65 - 10.10% DHF, 40% southbound - 60% northbound 9) Radisson Road -- 11.5% DHF, 35% southbound - 65% northbound 10) Lexington Avenue -10.2% DHF, 40% southbound - 60% northbound 11) Coon Rapids Boulevard - 10.5% DHF, 40% southbound - 60% northbound 12) TH 10/47 -10% DHF, 40% southbound - 60% northbound 13) Foley Boulevard - 11% OHF, 30% southbound - 70% northbound 14) East River Road -11.5% DHF, 20% southbound - 80% northbound 15) TH 47 -- 9.5% OIiF, 40% southbound - 60% northboWld 16) 1H 65 -- 10.7% OHF, 45% southboWld - 55% northbound 0E:11 v6. 01 ~n~
