Members Present: REPORT OF TRAFFIC REVIEW COMMITTEE Police Chief David Gustafson City Engineer Steve Jankowski Request: The Northfork Homeowners Association has requested, in a letter dated July 28, 1997, that a three-way stop sign be placed at the intersection of Andrie and 160th Avenue. Observation: City policy for posting all-way stops adopts those warrants acknowledged in the I991 Mimxesota Manual or Uniform Traffic Control. The three warrants for all-way stops include: Intersections where traffic signals are warranted and the all way stop is an interim use until signals can be installed. An accident problem as indicated by five or more accidents of a type susceptible to connection to multi-way stop signs. Minimum traffic volumes as follows: a) The total vehicular volume entering the intersection averages 500 vehicles per hour for any eight-hour period of the day b) The combination of vehicular and pedestrian volume from the minor street must average 200 units per hour for the same eight hours with an average delay to the minor street of 30 seconds per vehicle for the maximum hour. ~ ~ Warrant No. 1 obviously does not apply to this location. A review of poli. i.i~accide~ reports indicates no accidents of any type at this intersection between the period olh/ime-UTgXJ~and July 1, 1997, so Warrant No. 2 would not be meet. Warrant No. 3 is based primarily on traffic volumes. There are no specific traffic counts at this intersection, however, in 1995, there were traffic counts of 835 vehicles per day at Andrie, north of 153rd, and 165 vehicles per day on 164th Lane, east of Jarvis. A rough analysis of traffic generation based on the number of residences in the neighborhood suggests that ultimately there may be approximately 1,200 movements per day through the intersection. This would still be far short of the warrant which would require 4,000 vehicles during an eight-hour period. Staff has no estimate of pedestrian traffic in the area, nevertheless, the second part of Warrant No. 3 is premised on the issue that activity is causing a significant traffic delay which is not the case in this situation. Recommendation: It is the recommendation of the Committee to deny posting a three-way stop at this intersection. shared]engineering.ltd flit.doe
