1.0 BACKGROUND
Jim Mochan, a frequent traveller through the intersection of Concession Road 6
and Townline Road North, verbally expressed safety concerns regarding motorist
confusion surrounding this unusual 3 out of 4 way stop and suggested a safety
review.
2.0 COMMENTS
2.1 Boundary Road Intersection Between Clarington and Oshawa (Jurisdiction
and History):
This intersection is located on Townline Road North, which is a boundary road
between the City of Oshawa and the Municipality of Clarington, with Conlin Road
to the west and Concession Road 6 to the east. The Municipality of Clarington
presently maintains this portion of Townline Road North, but an ongoing review of
the Boundary Road Agreement may see maintenance activities on this road
section transferred to the City of Oshawa. Staff from Clarington, Oshawa and the
Durham Regional Police had previously met on site during 1992 to discuss this
intersection configuration. At that time it was agreed that the eastbound stop
control had to stay to ensure safety until Conlin Road could be reconstructed to
eliminate the danger caused by the vertical curve just west of the intersection. A
second review of motor vehicle collisions during 1999 indicated that only one
accident over a 5 year period from 1994 to 1998, could be partially attributed to
confusion cause by the three-way stop. The westbound traffic was therefore
permitted to continue travelling through the intersection unimpeded and the fourth
stop sign was not added.
2.2 Clarington Traffic Management Advisory Committee (CTMAC) Review 2002
Committee members were asked to review the location and provide their
comments on the existing intersection configuration. The committee members felt
that although collision records do not indicate that accidents are occurring due to
the unusual right of way controls, visual observations by Committee members
indicated that there does appear to be driver confusion and a significant disregard

for the existing stop sign for eastbound traffic. The CTMAC recommended
changing the intersection from the existing 3-way stop to an all-way stop.
During a discussion of the Townline Road North and Concession Road 6
intersection, it was noted by the Committee members that other 3 out of 4 way
stops could be found in Ontario but are rare and should not be permitted except in
unique circumstances.
Example #1 :
The M.T.O. controlled intersection of Baseline Road and Duke
Street, Bowmanville, which remains in place to ensure a free flow of
westbound traffic on Baseline Road onto the westbound 401 ramp.
If the intersection were an all-way stop it would cause traffic to
become congested and queue easterly back into the signalized
intersection at Liberty Street.
Example #2:
Northumberland County - Hwy 2 at County Rd 10 in Welcome north
of Port Hope which exists to ensure Hwy 2 traffic can make a turn
to the south to follow Hwy 2 without stopping on a grade to the west
of the intersection.

2.3 Staff Review
Motor Vehicle Collision History, Last Three Years:
Collision Number
01-60203
Date
June 1/01
01-4420
Jan 27/01
99-134326
Dec 11/99
Details
06: 10 pm eastbound vehicle stopped at
stop sign, second vehicle rear ended the
first.
01 :26 am northbound vehicle did not stop
for stop sign striking a westbound vehicle
at approx. 60 km/hr.
00:30 am eastbound vehicle braked for
stop sign on wet pavement, lost control
and drove into ditch.
None of these recent collisions were attributable to the existing 3 out of 4 way
stop configuration.
2.4 Intersection Turning Movement Study And Stop Sign Compliance Review
A four-hour traffic study was completed by Staff on January 22, 2002, between
2:00 p.m. and 6:00 p.m. to capture the peak afternoon volumes. In addition to the
basic turning movement counts, a tally was also kept of the number of "fail to
stop" for east bound traffic. The fail to stop tally consisted of vehicles which
travelled through the intersection at speeds that were considered in excess of the
usual rolling stops which many motorists make at urban and rural intersections.
Although the fail to stop tally is subjective, dependent upon the observer, it is still
considered important to note the disregard for the existing traffic control at this
intersection. The eastbound motorists approaching the stop sign all appeared to
see the stop sign and make a minimal attempt at reducing speed, but once seeing
the way was clear continued through the intersection without stopping. The
724
REPORT NO.: EGD-15-02
PAGE 5
Durham Regional Police Traffic Unit was requested to blitz this intersection over a
period of time to improve compliance and advise staff of their findings:
Jan. 22/02 Intersection Fail to Stop (high speed)
Period Volumes Observed by Staff
2-3 pm 137 7
3-4 pm 239 7
4-5 pm 281 14
5-6 pm 333 11
2-6 pm 990 39 (four hour summary)
During the four hour study there were two occasions when a motorist appeared
confused regarding the right of way and stopped within the intersection as other
traffic approached.
2.5 Existing Conditions and Suggested Intersection Improvements
There is an existing stop ahead sign 150 metres west of the intersection.
Eastbound motorists are within 90 metres of the intersection before they see the
oversized 90 x 90 cm stop sign. Sight distance of a northbound motorist from the
intersection looking west is limited to only 75 metres. If the eastbound stop
control were not in place the accident potential would increase significantly.
2.5.1 Reconstruction (Long Term)
Reconstruction of Conlin Road to improve sight lines is ultimately required to
eliminate the sight distance problems, but is not expected for several years.
Volumes are expected to increase with additional residential development in
Oshawa and the addition of a University Facility at Durham College, located on
Conlin Road at Simcoe Street in Oshawa.

2.5.2 Flashing Beacons
A flashing beacon either above the intersection or above the stop or stop ahead
signs does not appear to be warranted based on the relatively low number of
collisions at this intersection.
2..5.3 All-Way Stop
Although an all-way stop is not warranted based on existing intersection volumes
or collision history, it is seen as an improvement to eliminate the unusual 3-way
stop and could be implemented with the passing of a by-law to amend Traffic By-
law 91-58 by the Municipality of Clarington, with subsequent approval by the
Region of Durham. The City of Oshawa would not be required to make any by-
law amendment or approval to the change proposed by the Municipality of
Clarington.
2.5.4 Pavement Markings to Asphalt Surfaces
The addition of plastic stop bars on the approaches, and a yellow centre line to
the east of the intersection, may improve driver recognition and compliance. This
intersection improvement of plastic stop bars has been discussed with the City of
Oshawa who would provide the plastic stop bars in conjunction with Clarington
installing the additional stop sign. The two municipalities would share the costs of
this safety improvement.
2.6 Monitoring and Consultation
Staff from the Municipality of Clarington and the City of Oshawa have reviewed
and agreed to the recommendations of this report and will continue to monitor this
intersection to determine the need for further improvements, including the
timeframe for road and intersection reconstruction.
