Mr. Pat Klaers September 18, 1998 Page 2 3. Minimum Traffic Volumes: a) The total vehicular volume entering the intersection from all approaches must average at least 500 vehicles per hour for any 8 hours of an average day, and there were 8 hours in the day when the number of vehicles entering the intersection was at least 500. There are at least 500 vehicles entering the intersection between 11:00 a.m. and 7:00 p.m. b) The combined vehicular and pedestrian volume from the minor streets or highway must average at least 200 units per hour for the same 8 hours, with an average delay to the minor street vehicular traffic of at least 30 seconds per vehicle during the maximum hour, but there was only one hour, 4:00 p.m. - 5:00 p.m., when the total approach volume on 3rd Street was 200 or greater. Pedestrian counts were done for four of the eight peak hours, and these volumes were not high enough to bring any of the other hourly volumes above 200. The counts were found on the attached pages. The highest volume of pedestrian traffic was 11 pedestrians between 4:00 p.m. and 5:00 p.m. The average delay for the peak hour, 4:00 p.m. - 5:00 p.m., was 3 seconds, therefore this warrant was not met. c) When the 85th percentile approach speed of the major street traffic exceeds 40 mph, the minimum vehicular volume warrant is 70 percent of the above requirements. The speed limit on Gates Avenue is 30 mph, so 100% of the warrants must be met. Based on the fact that none of the warrants for the multi-way stop control are met at this intersection, it is our recommendation that stop signs not be added at northbound and southbound Gates Avenue at this time. For your information, we have attached a complete copy of the April 1997 multi-way stop sign warrant study. If you have any questions, please call. Sincerely, Howard R. Green Company Terry J.
