Bonestroo Rosene Anderlik - St. Paul, MN - (651)636'*1311 <br />Based on the warrant analyses, all-way stop sign control could be implemented at this <br />intersection now. By meeting the peak hour traffic signal warrant with the BRAA turning <br />movement volumes, a traffic signal may be justified at this location. Furthermore, several <br />warrants are close to being satisfied using either set of volumes. This suggests the intorsecfion <br />may justify a traffic signal baaed on several warrants in the near future. <br />Crash data can be used to satisfy one traffic signal warrant and one all-way stqi control warrant. <br />Both require 5 or more correctable crashes within a 12-month period (The traffic signal warrant <br />also requires minimum volumes). Correctable crashes are those that would likely be prevented <br />widi the new intersection control, such as a right angle crash. From January 1 to December 31, <br />2002, Mn/DOT recorded 4 crashes at this Intersection. Three of these crashes would likely be <br />correctable with either signal or all-way stop sign control. However, this does not satisfy the <br />crash ejqierience warrant. The full warrant analyses are provided in the appendix of this report <br />Besides a traffic control change, turning lanes could be added to the intersection of CSAH 6 and <br />Willow Drive to improve the capacity. Based iqran the existing condition and volumes, the most <br />benefit would likely be gained by providing one left turn lane, one through lane, and one right <br />turn lane for the eastbound and westbound aiq|)toacbes on CSAH 6. Willow Drive would also <br />benefit firom providing one left turn lane, one through lane, and one right turn lane on the <br />northbound and southbound approaches to the intersection. <br />To fully examine the possible benefits from the additional lanes and/or a traffic control change, <br />the intersection was re-analyzed with each feature during the a.m. and p.m. peak hours. Table 3 <br />shows the results of the new capacity analyses during the a.m. peak hour. Table 4 shows the <br />results during the p.m. peak hour. As before, the 95" percentile queue lengths are also (wesented <br />with the level of service results. <br />CSAH 6 & Willow Dr Intersectioo Review City of OroQO <br />.4 .
