l t <br /> Clark Lohr February G,2006 <br /> Along with proposed limitation of the access to right-in/cight-out only,construction of a turn lane to allow <br /> eastUound right-turning vehicles to e�it the mainline traffic stream prior to entering the site is suggested <br /> as a proactive s�fety measure. Based on the site survey conducted, it appears such 1 turn (ane could be <br /> constructed using much of the e�isting shoulder. The turn lane shou(d however Ue constructed to the <br /> design standards of the appropriate regulatory agency (Hennepin County or MnDOT, clepending on the <br /> exact timing of the project). It is anticipated that the design of the t�u�n fane will require a 15:1 tapec and <br /> 260 feet of parallei deceleration length, based on a 50 mph design s�eed. <br /> Conclusion <br /> Based on the results of this analysis, the addition of approximately 2,000 daily trips to the study area <br /> roadway network could, in general, slightly increase the delay and queue lengths at nearby intersections, <br /> most notabfy Wayzata Boulevard/Old Crystal Bay Road. .However, results of the operational analysis <br /> indicate thlt ii�tersection opecations will remain largely unchanged, and within typically accepted limits. <br /> In pa��ticular, results of the analysis indicate that the proposed right-in/right-out access on Trunk Highway <br /> 12 will operate at acceptable levels of service for botl� mainline and side street traffic with no delay to <br /> mainline tcaffic. <br /> Althougl� not necessary in terms of operations, as demonstrateci by the analysis conducted, it is suggested <br /> that a right turn lane be constructed/striped on Wayzata Boulevard meeting applicable Hennepin County <br /> or MnDOT design standards, depending on jurisdiction at the time the lane is to be designed/built. It is <br /> anticipated that such a design would require a 15:1 taper and 260 feet of deceleration length. Adding a <br /> turn lane as a proactive safety measttre would help in maintaining safe operations at this access. <br /> RLK(nc.
