The need for the traffic study is the result of the proposed inclusion of a liquor store in the convenience store complex. The traffic study follows the request from the City of Roseville staff and the Roseville Planning Commission. Existing Traffic Volumes Based on Minnesota Department of Transportation Metropolitan Series Traffic Flow Maps, Lexington A venue north of County Road B has an average daily traffic volume of 16,500. South of County Road B, the volume is 15,600. Volumes on County Road Bare 10,000 to the west and 7,400 to the east. Volumes have changed little in the past 10 years. The 1992 volume map from the same source shows volumes on Lexington Avenue of 18,000 vehicles per day to the north and 16,000 to the south of County Road B. Volumes on County Road Bare 10,000 to the west and 7,000 to the east. Review of similar maps in 1990 and 1994 show that the volumes are relatively similar. Thus, there is little volume growth on Lexington Avenue or on County Road B based on historical trends. The most recent tUl11ing movement counts at the intersection of Lexington A venue and County Road B were made in 2001 by Ramsey County. The volumes are consistent with the average daily traffic shown on the Mn/DOT maps. The turning movement counts were made for three 2-hour periods including a.m. and p.m. rush hours and midday. The turning movement counts show the 2-hour westbound approach volumes on County Road B as 702 from 7:00 a.m. to 9:00 a.m., 516 from 11 :00 a.m. to 1 :00 p.m., and 639 from 4:00 p.m. to 6:00 p.m. Southbound volumes approaching the intersection in the same three periods are 926, 1,240, and 1,324, respectively. To detelmine the traffic generated by the convenience store and to better understand traffic flow in and out of the four driveways, a 2-hour turning movement count at the four driveways was made in the p.m. peak period. As expected, the counts showed little very traffic making left tUl11S from the station to the southbound Lexington Avenue. Only 16 left tUl11S were made in the 2-hour peliod with 13 at the north dliveway. Left turns from the south driveways to eastbound County Road B Short Elliott Hendrickson Inc.
