r <br />k <br />Bonestroo Rosene Anderlik - St. Paul, MN - (6S1)636-1311 <br />Based on the infonnation in the two previous tables, the conditions at the intersection would <br />inq>rove with die proposed turn lanes, except under all-way stop control. All-way stop control <br />appears to work tte best with the existing t^-pass lanes. This is due to the ability of through <br />tradBc on CSAH 6 to use either lane to travel through the intersection, rather than backing up in <br />only one lane. <br />Safety Improvements <br />The safe^ of the intersection could be improved through either a traffic control change and/or <br />sight distance inqirovement. As noted in the previous section, all-way stop is currently <br />warranted for the intersection. A traffic signal is also wananted based on BRAA collected <br />turning nxivement counts for the intersection of CSAH 6 and Willow Drive. A traffic control <br />change is only effective if the accident experience at the intersection shows correctable crashes, <br />such as right angle crashes. In this case, 12ofthe 18 crashes would likely be corrected by either <br />all-way stop or traffic signal control. A traffic control change at this intersecdon would likely <br />improve safety based on this informadon. <br />The sight distance to the east on CSAH 6 is currenUy well short of Mn/DOT road design <br />standards. Re-grading the road to improve the slope and improve the sight distance would likely <br />benefit safety at this intersecdon. To provide this improvement, the east leg of the intersecdon <br />would need to be lowered by about 1 foot over a distance of approximately 600 feet <br />Finally, another safety improvement could be made if the proposed geometry of the previous <br />intersecdon is implemented. Providing a raised, concrete me^an on CSAH 6 at the intersecdon <br />would physically separate the two direcdons of traffic. Medians are e^iecially effecdve on high <br />qreed roadways such as this CSAH 6. <br />Figures 3 and 4 show the intersecdon wifo the prv^osed capacity and safety improvements. <br />CSAH 6 A Willow Dr Intersection Review -9-City of Orono <br />4»...... an <br />4 <br />J
