• This report supports the delivery of core services.
BACKGROUND:
Transportation Services received a request to review safety issues at the intersection of Mill
Street and Spadina Road East. Concerns from residents cited that northbound vehicles on
Mill Street, turning left onto Spadina Road East, frequently encroach into the eastbound left
turning lane on Spadina Road East, thus creating safety concerns for road users. Residents
specifically requested that Transportation Staff review the intersection for safety.

REPORT:
The intersection of Mill Street (north -south) and Spadina Road East (east -west) is a 3 -legged
intersection with Stop control on Spadina Road East. According to the City of Kitchener's
Official Plan, Spadina Road East is designated as minor community collector road and Mill
Street is designated as an arterial Roadway. Currently, the traffic on Spadina Road east
stops and yield right-of-way to the traffic on Mill Street.
In response to resident concerns, staff conducted site investigations, a turning movement
count, and a historical collision review of the intersection. The results of the study were
compared to the City of Kitchener's All -Way Stop warrant requirements. These requirements
are a set of guidelines based on the all -way stop warrants established by the Ministry of
Transportation of Ontario and the Institute of Transportation Engineers. The intersection
was compared to the warrants for both a collector road /arterial road. The results are as
follows:
Warrant — Collector /Arterial Road

Warrant Factors - "3 -Leg" Intersection
Results
Warrant Met
The total vehicle volume on all
intersection approaches averages at
281
NO
least 500 vehicles per hour for each of
any eight hours of the day,
and
The volume split does not exceed 70% /
65%/35%
YES
30% on the major road,
or
Average of at least 4 collisions per year
over a three-year period (susceptible to
1.00 per year
NO
correction by an All Way Stop)
All -Way Stop Warranted NO
Based on the above, the intersection does not warrant additional traffic control. However,
traffic volume data collected since 2015 have demonstrated that Mill Street is functioning
more like a minor community collector street versus an arterial road. Traffic volumes have
consistently carried less than 3,000 vehicle trips per day since 2015. This can at least be
partially attributed to changes to the road network at Mill Street and Ottawa Street South.
LRT construction eliminated the direct route along Mill Street from Queen Street South to
Courtland Ave East and to Hwy 8. Based on existing conditions, staff also analyzed the
intersection under the assumption that Mill Street functions as a minor collector roadway for
the purpose of the All -Way Stop Warrant Analysis. The results are as follows:
Warrant — Local/Minor Road

Results
Warrant Met
The total vehicle volume on all

YES
least 250 vehicles per hour for each of
any eight hours of the day,
and
The volume split does not exceed 75% /

or
Average of at least 4 collisions per year

All -Way Stop Warranted YES
As the results above indicate the intersection of Mill Street and Spadina Road East does not
meet the all -way -stop warrant when Mill Street is considered an arterial roadway, but does
meet the warrant when Mill Street is considered a minor collector roadway. Although Mill
Street is identified as an arterial roadway in Kitchener's Official Plan, it has been functioning
more like a minor collector roadway based on volumes since 2015. Given the reduced
volumes on Mill Street, Transportation Services expects the all -way stop to function
appropriately, and is recommending that an all -way stop be installed at the intersection.
STRATEGIC PLAN ALIGNMENT:
This report supports the delivery of core services.
FINANCIAL IMPLICATIONS:
Capital Budget — The recommendation has no impact on the Capital Budget.
Operating Budget — The recommendation has a total estimated budget impact of $1,000 on
the Operating Budget. These costs can be absorbed in the existing Sign Maintenance
budget.
COMMUNITY ENGAGEMENT:
INFORM — This report has been posted to the City's website with the agenda in advance of
the council / committee meeting.
