PAUL "'SeJ May 31,2000 RE: Roseville, Minnesota Minnesota Department of Transportation Regional Transportation Management Center SEH No. A~ROSEV9801.00 Ms. Debra Bloom Assistant Public Works Director City of Roseville 2660 Civic Center Drive Rosevi11e, MN 55113 Dear Deb: We have completed a traffic study of the transportation impacts of the Regional Transportation Management Center being developed as an addition to the MnlDOT Waters Edge Building on County Road B2. I[ does not appear that the traffic volumes generated by the addition will create any o,?erational problems on County Road B2 or other area stre~. There are a few on-site circulation concems based on the small scale documents which were provided for review. MnlDOT has estimated there are 637 employees in the building c~ently. There will be 84 employees in the Regional Transportation Management Center eRTMC). MnlDOT currently has both flex hours and shift hours in effect. The flex hours aHow employees to begin and end their working day outside of the normal peak hOUTS. Employees are leaving between 2:30 and 6:00 p.m. in the afternoon depending on their start time. Some employees begin work prior to the moming rush hour traffic as part of the management center strategy, or flex hours. A turning movement count at the intersection of County Road B2 and the MnfDOT entrance was made from 3:00 to 5:00 p.m. This would be the time when most traffic is leaving the building and when there is most conflict with the Rosedale area commercial traffic. The A.M. Peak Period does not have the commercial traffic conflicts and is entering the Mn/DOT site, therefore having less conflicts. The peak 15 minute period was from 4:00 to 4:15 p.m. and had 50 northbound vehicles. During the two hours, there was an average of 33 vehicles in each IS-minute period, or an average of approximately two vehicles each minute. Wjth some peaking characteristics, there is some delay associated with leaving traffic. Traffic northbound leaving the site is split 56 percent 1eft turns an~ 44 percent right.turns. '.The employees in the RTMC will not all be additions to Waters Edge. There are some RTMC employees currently in the building who will merely move to different areas. Also, a number of RTMC employees cUITently start early working as earty as 6:00 a.m. to mid-afternoon, and others start in the late a.m. and work through the p.m. peak period. Therefore, the RTMC will add little peak period traffic to the-existing volumes. Shon Elliott Hendrickson Inc. OfflCBS located throughout the Upper Midwest we lulp you plan, desigrt. a1l4 adtinlt.
