Dennis Welsch May 9, 1996 Page 3 The signalized traffic operations along CR B and Hamline A venue allow protective/permissive phasing in tillS area, except for the State Farm intersection, where protected only phasing on CR B is present. Existing Traffic Volumes The existing average daily traffic (ADT) demands on the major access roadways to/from the site were obtained from 1994 MnDOT Traffic Flow Maps. These ADT's are shown in Figure 3. The data indicate that the existing ADT's in this area are: TH 36 - 74,000 vehicles per day (vpd), TH 51 - 42,000 vpd, CR B - 16,500 vpd and Hamline Avenue- 10,500 vpd. The existing peak hour traffic demands were detemlined by traffic count,> conducted by BRW, Inc. personnel during April of 1996. Because of the retail nature of this area. both weekclay and weekend counts were conducted. The weekday counts were conductec1 from 4:00 to 6:00 PM at the CR B intersections with TH 51, State Farm Road, Pascal Avenue and Hamline A venue and the Commerce Street intersections with Pascal A venue, N. Albert Street and Harnline A venue. The data indicated that the existing weekday PM peak hour in this area is from roughly 4:30 to 5:30 PM. The weekday PM peak hour traffic demands at each of the key intersections are shown in Figure 4. The weekend counts were conducted from Noon to 3:00 PM at the CR B intersections with TH 51, State Farm Road and Harnline Avenue and at the Commerce Street/Harnline Avenue intersection. The data indicated that the existing weekend-day peak hour in this area is roughly from 12: 15 to 1: 15 PM. The weekend-day peak hour traffic demands at each of the counted intersections are shown in Figure 5. Existing Site GenerationlDistribution The existing weekday peak hour traffic generation and distribution to/from the State Farm site was determined by traffic counts and vehicle trace studies conducted by BRW, Inc. personnel in April of 1996. The generation to and from the office building was determined by counting inbound and outbound traffic to/from each of the six access driveways to/from the office building site and the three access driveways to/from the overflow surface parking lot south of Commerce Street. The data indicated that the existing weekday PM peak hour (4:00 to 5:00 PM) traffic generation to and from the site was 60 inbound vehicles and 516 outbound vehicles. The distribution of traffic from the office building to the adjacent roadway system was determined by following exiting vehicles until they crossed a predetermined cordon boundary (Figure 6). Distribution percentages were then calculated for each of the major access roadways that cross the cordon boundary from the site based on the fifty trace studies that were conducted. The resulting distribution percentages are shown in Figure 6. The data indicate that the vast majority (66 percent) of traffic from the site during the weekday PM peak hour is oriented towards the east on TH 36 (40 percent) and north on Hamline A venue (26 percent).
