CONSIDER REPLACEMENT OF EXS[STING .YEILD SIGN WITH A STOP SIGN AT MARMOSET AND 154TB LANE By: Steve Jankowski, City Engineer Case # Background: A~'~ email request has been received from Colleen Fischer for the replacement'of Yield signs for 154th Lane with Stop signs at its intersection with Marmoset Street. The location r:f rials intersection is illustrated on the attached figure. Staff has reviewed the intersection and offers the following information as background in considering this request. Accident history A review of the police department records dating back to 2000 show no reported accidents at this intersection. Traffic Traffic counts were taken between the 24 hour period between Wednesday October 12, 2005, and Thursday, October 13, 2005 The results of this traffic volume study are illustrated on the attached figure which show: 194 vehicles per day on the north leg; 71 vehicles per day on the west leg; 98 vehicles per day on the east leg; and 195 vehicles per day on the south leg. Sight Distance There is an adequate sight distance for the northbound and eastbound approaches into this intersection. There is a large evergreen tree located on the northeast comer of the intersection which impacts the visibility between approaching southbound and westbound traffic. However, a westbound vehicle slowing reasonably to yield to Marmoset Street has adequate sight distance to yield to southbound traffic. Discussion: The Minnesota Manual on Uniform Traffic Control Devices (MNMUTCD) provides $~idance on the placement of both Stop and Yield Sign~. Particularly applicable to this si'~c~ation the manual advises that a Yield sign may be used instead of a Stop sign when ~i~c ability to see all conilicting traffic is sufficient to allow a road user traveling at the r)o:<ed speed (30 mph) to travel tkrough the intersection or to stop in a reasonably safe r~nanner. The manual now provides support which states that in many low traffic volume situations with no unusual history of intersection crashes, no control is a cost effective{ s~r-~tteg},. Furthermore, it offers that research shows that in most cases ingreasing the.~V-~e! (,i' i~tersection control will not improve safety. This intersection can be considered as a i~,w volume intersection as is evidenced by the daily traffic counts referenced above.
