OCT 15 '93 16: 12 MN DOT ERAINERD P.7 <br /> Mr. Pat Klaers <br /> October 15, 1993 <br /> Page 3 <br /> • <br /> >> We assumed the traffic generation from the proposed development calculated <br /> by Benshoof and Associates to be realistic. <br /> >> Actual signal. timing parameters were used to evaluate the signalized inter- <br /> section operation. This yielded a 150-second cycle length at T.H. 169 and <br /> School Street. <br /> >> An overall intersection level of service (LOS) was calculated to be "E" <br /> at T.H. 169 and School Street in 1997. (This calculation took into account <br /> a widened School Street as proposed by Benshoof, and a dual left turn lane <br /> for NB T.H. 169.) "E" is an acceptable LOS for short periods of time. <br /> >> There are improvements that can be made to the highway and the intersecting <br /> street to minimize the impacts due to increased traffic. <br /> -- Dual left turn lanes for northbound T.H. 169. <br /> -- Dual left turn lanes for eastbound School Street. <br /> -- Additional lanes for through movements on T.H. 169 and/or School Street. <br /> >> Should the development and expected traffic increases occur, dialogue will <br /> need to be conducted between the City and the Department of Transportation <br /> co identify short term and long term roadway improvements. <br /> Sincerely, <br /> avt.."-L6'iG‘17r-s <br /> Anthony J.
