Data from Trip Generation, 7 Edition The distribution of site - generated traffic from and to the adjacent street system was based on existing traffic patterns. Trips added due to site - generated traffic were assigned based on these distribution percentages. Figure 4, titled "Trip Distribution & Assignment," illustrates the distribution pattern and the estimated change in peak hour traffic volumes within the study area expected as a result of the proposed development. Figure 5 shows the resulting Build scenario peak hour traffic volumes. Traffic Operations Operations within the study area were analyzed using the industry- current Synchro /SimTraffic 6 software package, which use the data and methodology contained in the 2000 Highway Capacity Manual, published by the Transportation Research Board. The operating conditions of transportation facilities, such as roadways, traffic signals and stop - controlled intersections, are evaluated based on the relationship of the theoretical capacity of a facility to the actual traffic volumes on that facility. Various factors affect capacity, including travel speed, roadway geometry, grade, number and width of travel lanes, and intersection control. The current standards for evaluating capacity and operating conditions are contained in the 2000 Highway Capacity Manual. The procedures describe operating conditions in terms of a Level of Service (LOS). Operations are given letter designations with "A" representing the best operating condition and "F" representing the worst. Generally, Level of Service "D" represents the threshold for acceptable overall intersection operating conditions during a peak hour. Results of the operational analyses for 2005 Existing PM peak hour conditions show that the south intersection within the I -35W /CSAH 23 interchange operates at an overall failing level of service with the eastbound approach also at a failing level of service and long queues. As noted above, MnDOT and Anoka County plan to improve the I -35 W /CSAH 23 interchange in 2007. Since any improvement or mitigation measure implemented at the interchange prior to that time would be removed, only temporary improvements with minimal cost are likely to provide any net benefit.
