Stop Sign Memo June 21, 2017 Page 2 G:\Group Data\Traffic\Arden Hills\Chatham Ave & Mccraken Ln\Arden Hills Stop Sign Request Memo.doc Intersection Evaluation The intersection of Chatham Avenue and McCracken Lane was evaluated for an All-Way Stop control based on the Minnesota Manual of Uniform Traffic Control Devices (MnMUTCD). An All-Way Stop warrant analysis was completed using the MnDOT warrant template. MnMUTCD According to section 2B.7 of the MnMUTCD, the decision to install a Multi-Way Stop control (All-Way Stop in this case) should be based on an engineering study. The following criteria should be considered in the engineering study for a Multi-Way Stop sign installation: A. Where traffic control signals are justified, the Multi-Way Stop is an interim measure that can be installed quickly to control traffic while arrangements are being made for the installation of the traffic control signal . A traffic signal is not justified at this intersection. B. Five or more reported crashes in a 12-month period that are susceptible to correction by a Multi- Way Stop installation. Such crashes include right-turn and left-turn collisions as well as right- angle collisions. A review of MnDOT’s accident database (Minnesota Crash Mapping Analysis Tool, MnCMAT) over the past 3 years (2013-2015) revealed that no crashes were documented at this intersection. C. Minimum Volumes 1. The vehicular volume entering the intersection from the major street approaches (total of both approaches) averages at least 300 vehicles per hour for any 8 hours of an average day. At this intersection, there were no hours during the day that meet criteria C.1. Less than 150 vehicles enter the intersection during the PM peak hour, and less than 100 enter during the AM peak hour. These volumes are significantly less than the required minimum volumes for an All- Way Stop control. See the attached All-Way Stop warrant spreadsheet in the Appendix D. 2. The combined vehicular, pedestrian, and bicycle volume entering the intersection from the minor street approaches (total of both approaches) averages at least 200 units per hour for the same 8 hours, with an average delay to minor-street vehicular traffic of at least 30 seconds per vehicle during the highest hour; but At this intersection, there were no hours during the day that meet criteria C.2. See the attached All-Way Stop warrant spreadsheet in Appendix D.
