OCTOBER 21, 1987
The matter was introduced by City Manager Peterson. The
following staff report was given by Public Works Director
Ronsko:
At the regular Council meeting of September 2, 1987, the
City Council received a request regarding speed problems on
School Street. At the request of the City Council, staff
performed a traffic study on School Street in comparison to
similar streets in the area.
The study included 24-hour vehicle counts, radar speed
surveys, a four-way stop control study, and an accident
review.
The traffic data on Lee Street, Pleasant Avenue, and Church
Street north of Kettleman Lane, was compared to School
Street.
Traffic Volume Counts t
}
The daily traffic volume on School Street is 2,130
vehicles. The traffic volume on Church Street is more than
three times as much as School Street (6,710 vehicles per
day). Lee Street has 1,030 vehicles per day and Pleasant
Avenue has 480 vehicles per day.,

Radar Sury IT
{
s
The prima facie limit on Lee Street, Pleasant Avenue, and
School Street is 25 mph. Church Street from Kettleman Lane
to Tokay Street has a posted speed limit of 35 mph.
The results of the radar sur.ey data showed that all three
25 mph streets have 85th percentile speeds greater than the
prima facie limits. The 85th percentile speed is the speed 4
at or below which 85% of the traffic is moving. This speed
is a major factor in determining posted speed limits.
Smaller speed samples were taken on Lee Street and Pleasant
Avenue due to the low traffic volumes. There could be a
slight variation in the speed results on Lee Street and
Pleasant Avenue due to the smaller speed samples.
