Public Works Committee 5. 1. Meeting Date: 06/18/2013 Submitted For: Grant Riemer By: Grant Riemer, Engineering/Public Works Title: Consider Stop Sign Request for 3-Way Stop at Tiger St and 171st Ave Background: The attached petition was received May 30 2013 from residents near the intersection of Tiger St and 171st Ave. The purpose of the petition is to request a 3 way stop at the above intersection. There is already a stop sign at 171st Ave where it intersects Tiger St., so technically we would be only adding stop signs to Tiger St. Staff has reviewed the intersection and offers the the following information as background in considering this request. The City of Ramsey follows the guide lines for stop sign installations provided in the Manual on Uniform Traffic Control Devices (MUTCD). Because the STOP sign causes a substantial inconvenience to motorists, it should only be used when warranted. The following are the recommended guidelines or warrants for the installtion of a Multiway Stop Sign. 1. Where traffic signals are warranted and urgently needed, the mulitway stop in an interim measure that can be installed quickly to control traffic while arrangements are being made for the signal installation. 2. An accident problem, as indicated by five or more reported accidents of a type susceptible of correction by a multiway stop installation in a twelve month period. Such accidents include right and left turn collisions as well as right angle collisions. 3.Minimum traffic volumes A) the total vehicular volume entering the intersection from all approaches must average 500 vehicles per hour for any 8 hours of an average day, and B) The combined vehicular and pedestrian volume from the minor street or highway must average 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 maximum hour. Notification: Notification has been sent to residents who's name appeared on the petition. Observations/Alternatives: Speed Limit The posted speed limit on all three legs of the intersection is 30 mph Accident History According to Ramsey PD records there are no reported accidents since at least 2000 when their present software system was installed, with the exception of a deer/vehicle collision on Tiger St. Traffic data Traffic counts were taken for two 24 hour periods, starting May 29th and ending May 31 st. Traffic counts are taken in this manner to determine a 24 hour average.
