Provide direction to staff if Council wishes to change current policy. Background This report is a follow up on a matter discussed at the May 8, 2006 Council meeting, regarding uncontrolled intersections (no stop or yield signs in any direction) in the City, and policy for consideration of stop or yield signs at such locations. State and Federal standards establish guidelines for installation of stop control at uncontrolled intersections, and the following summarizes the conditions where stop signs should be used: . A street or minor road intersects a main road; and/or . Most intersections in the immediate area are controlled by traffic signals; and/or . High speeds, restricted view, or crash records indicate need for stop sign control. The guidelines also state that stop signs should not be used for speed control. At intersections where a full stop is not necessary at all times, the guidelines state that less restrictive measures such as yield signs should be considered. Once a decision has been made to install two-way stops at a four-way intersection, one of the two intersecting streets must be selected for stop control, typically the street carrying the lowest traffic volume. For installation of multi-way stop signs, additional StateIFederal criteria apply, which can be summarized as follows: . Five or more reported crashes in a 12~month period; or . Minimum volurnes: Major street volume averages at least 300 vehicles per hour for 8 hours, ;~1nd minor stn:~et combined vehicle/pedestrian/bike volume averages at least 200 per hour for the same 8 hours, and average delay to minor-street traffic at least 30 seconds during the highest hour; Of . A least 80% of all these values from both preceding criteria are satisfied. The guidelines state that multi-way stop control is used where the volume of traffic on the intersecting roads is approximately equal. Other criteria that may be considered for multi-way stop signs include: . Need to control left-turn conflicts; . Control of vehicle/pedestrian conflicts near high pedestrian volume generators; Page 1 of4 ,- -
