Date: May 9, 2016
From: Richard Holborn
Director, Engineering & Public Works
Subject: Proposed All-way Stop Control, Liverpool Road and Wharf Street
- File: A-1440
Recommendation:
1. That the attached draft by-law be enacted to amend Schedule "7" to By-law
6604/05 to provide for the regulation of stop signs on highways or parts of
highways under the jurisdiction of The Corporation of the City of Pickering,
specifically to address the proposed installation of an all-way stop control at the
intersection of Liverpool Road and Wharf Street, and
2. That the appropriate officials of the City of Pickering be authorized to take the
necessary actions as indicated in this report.
Executive Summary: In response to concerns from area residents, specifically
with respect to sightlines and vehicle volumes, Engineering & Public Works staff
completed reviews for all-way stop control at the intersections of Liverpool Road at
Wharf Street and Liverpool Road at Commerce Street. Based on vehicle and pedestrian
volumes and collision history, neither intersection met the requirements for an all-way
stop, in accordance with the City's Safer Streets Traffic Management Strategy.
However, sightline issues are recognized for both intersections when vehicles are
parked on Liverpool Road, which occurs routinely between May and September. The
sightline concern is more evident at the intersection of Liverpool Road and Wharf Street,
since vehicles park on both sides of Liverpool Road both north and south of the
intersection. The traffic count also indicated that there are slightly more vehicles exiting
from Wharf Street than from Commerce Street. It is also recognized that during the
months of May to September, Liverpool Road and adjacent streets have increased
vehicle and pedestrian activity and parking demand due events at Pickering's Nautical
Village.
Engineering & Public Works staff completed community consultation for a proposed all-
way stop control at the intersection of Liverpool Road and Wharf Street. The letter and
survey was sent to 944 homes and was also placed on the City's Facebook and Twitter
accounts. The survey generated 59 replies with 36 (61%) in support of an all-way stop
at the intersection of Liverpool Road and Wharf Street and 23 (39%) opposed.
Therefore, based on the sightline concern, results from the community consultation and
in order to allow a safe place for pedestrians to cross Liverpool Road, Engineering &

Public Works staff recommend the placement of an all-way stop control at the
intersection of Liverpool Road and Wharf Street.
Financial Implications: The installation of stop signs, advance warning signs, and
stop bar and pavement markings at the intersection of Liverpool Road and Wharf Street
can be accommodated within the 2016 Roads Current Budget.
Discussion: In January 2015 Engineering & Public Works staff received a request from
two area residents on Pleasant Street to investigate the installation of an all-way stop at
the intersection of Liverpool Road and Commerce Street. In April 2015 Engineering &
Public Works staff received a request from an area resident on Wharf Street to
investigate the installation of an all-way stop at the intersection of Liverpool Road and
Wharf Street. Another request from an area resident on Wharf Street was later received
in September 2015 to investigate an all-way stop at Liverpool Road and Wharf Street.
All residents have expressed safety concerns, specifically with respect to sightlines and
vehicle volumes.
In response to these concerns, Engineering & Public Works staff completed a review of
both the Liverpool Road and Wharf Street and Liverpool Road and Commerce Street
intersections, which included the following investigations:
• collection of vehicle and pedestrian volumes at both intersections in the spring and
summer months
• review of sightlines and road geometry for both intersections
• review of collision history for the previous five years for both intersections
• observations of vehicle volume and pedestrian activity on Liverpool Road from
Commerce Street to the southern limit during the spring and summer months
• community consultation with residents and businesses
The results of the review and recommendations are presented in the following sections:
An all-way stop control would not be warranted based on vehicular and
pedestrian volumes at either intersection
To determine if an all-way stop control is required at the intersection of Liverpool Road
and Wharf Street and the intersection of Liverpool Road and Commerce Street, staff
completed municipal all-way stop warrants, in accordance with the City's Safer Streets
Traffic Management Strategy. The City's All-way Stop Warrant calculates whether an
all-way stop control is required, taking pedestrian and vehicular volumes, reported
collision history and sightlines into consideration.

Eight-hour vehicle and pedestrian turning movement counts were completed at the
intersection of Liverpool Road and Wharf Street, and at the intersection of Liverpool
Road and Commerce Street on Tuesday, April 28, 2015 and Wednesday, May 20, 2015
respectively. The specific time periods for the traffic count were 7:00 am to 9:00 am,
11:00 am to 1:00 pm and 2:00 pm to 6:00 pm. The peak hour for both vehicular and
pedestrian traffic for the morning peak periods at the intersections were 8:00 am to 9:00
am. The afternoon peak period for the intersection of Liverpool Road and Wharf Street
was 3:15 pm to 4:15pm, and for the Liverpool Road and Commerce Street intersection it
was 4:30 pm to 5:30 pm.
In addition to the eight-hour turning movement counts, 24-hour vehicle volume counts
were completed over seven days from Saturday July 18, 2015 to Friday July 24, 2015
using a mechanical vehicle counter classifier (road tubes).
It is also recognized that during the summer months (May to September) Liverpool
Road has increased vehicle and pedestrian activity and parking demand due to
Pickering's Nautical Village being located at the southern limit of Liverpool Road.
Pickering's Nautical Village is a popular tourist destination and features many summer
activities including free musical entertainment at Millennium Square on Thursday
evenings, playgrounds for children, the Waterfront Trail, dragon boats, sailing, as well
as many different shops, businesses and restaurants. This increased vehicle and
parking demand is evident as vehicle and pedestrian volume generally effects adjacent
streets due to the limitation of parking spaces at Millennium Square.
However, the City's warrants for all-way stop controls were not met, in accordance with
the City's Safer Streets Traffic Management Strategy, based on both the vehicle and
pedestrian turning movement counts and the 24-hour vehicle volume counts, with
Warrant 2: Minimum Vehicle Volume not being satisfied. The traffic counts did indicate
however, that of the two locations, the intersection of Liverpool Road and Wharf Street
had a slightly higher volume of vehicular traffic exiting than the intersection of Liverpool
Road and Commerce Street.
The all-way stop warrant analysis for the intersection of Liverpool Road and Wharf
Street, and for the intersection of Liverpool Road and Commerce Street can be found in
Attachment 1 and Attachment 2 respectively.
There are no reported collisions in the last five years at either intersection that is
correctable by the installation of an all-way stop
In the previous five years, there were no reported collisions that would be correctable by
the installation of an all-way stop at the intersection of Liverpool Road and Wharf Street
and at the intersection of Liverpool Road and Commerce Street.
The City's All-way Stop Warrant requires there to be an occurrence of three or more
reportable collisions per year, averaged over three years, correctable through the
CORP0227-07/01 revised
ENG 10-16 May 9, 2016
Subject: Proposed All-way Stop Control
Liverpool Road and Wharf Street Page 4
installation of all-way stop controls. Therefore, an all-way stop control is not warranted
at either intersection based on collision history.
Vehicle traffic can be difficult to see when exiting from both Wharf Street and
Commerce Street when vehicles are parked on Liverpool Road
The on-street parking on Liverpool Road at Wharf Street and at Commerce Street make
it challenging for drivers to exit these streets onto Liverpool Road.
At Wharf Street specifically, on-street parking exists both north and south of the
intersection on both sides of the road. This makes it difficult for drivers on both
approaches of Wharf Street to see oncoming traffic on Liverpool Road, particularly in
the summer months. Sightlines are less than 50 metres at the intersection when
stopped at the stop bar, however, sightlines are improved to greater than 60 metres
when moving forward towards to the edge of the intersection.
At Commerce Street, on-street parking exists only on the west side of Liverpool Road
south of the intersection. This makes exiting Commerce Street difficult for drivers on
the west approach, particularly in the summer months.When stopped at the stop bar
sightlines are impacted by on-street parking and a hedge on the southwest corner of the
intersection. Sightlines are less than 50 metres at the intersection when stopped at the
stop bar, however, sightlines are improved to greater than 60 metres when moving
forward towards to the edge of the intersection. City staff are currently looking into
options to improve the sightline at this corner and have had a discussion with the
business that has been parking vehicles on Liverpool Road at Commerce Street, and
will be speaking with the homeowner on the southwest corner about the partial removal
of the hedge that is on the corner.
Based on the above investigation by the City of Pickering staff, the vehicle and
pedestrian volumes and collision history at these intersections do not meet the
requirements for an all-way stop. However, the City of Pickering has installed all-way
stop control at intersections where sightline issues are recognized. It is recognized by
City Staff that there are sightline issues at both intersections when vehicles are parked
on Liverpool Road, which occurs routinely in the summer months.
Due to the close distance between Commerce Street and Wharf Street on Liverpool
Road, the City is recommending installing an all-way stop control only at one location.
Furthermore, because the sightline concern is more evident at the intersection of
Liverpool Road and Wharf Street and since the vehicle volume is slightly greater at
Wharf Street, particularly in the summer months, Engineering & Public Works staff
completed community consultation for a proposed all-way stop control at the
intersection of Liverpool Road and Wharf Street.

Feedback from residents received by City staff indicates that the majority of area
residents support an all-way stop at Liverpool Road and Wharf Street
A letter dated February 10, 2016 was sent to area residents, 944 homes, within the
area. The letter indicated that City staff was proposing an all-way stop control at the
intersection of Liverpool Road and Wharf Street, and provided area residents an
opportunity to review and provide comments on the proposed all-way stop control, as
well as to indicate their support or opposition. The survey was also promoted on the
City's Facebook and Twitter accounts asking residents to complete the survey and
provide their feedback.
The letter and survey to residents generated 59 replies. A summary of those that were
in support and those that were opposed are as follows:
• 36 replies (61%) were in support of an all-way stop control at Liverpool Road and
Wharf Street, 7 of which were in response to the Facebook and Twitter posts
• 23 replies (39%) were opposed to an all-way stop control at Liverpool Road and
Wharf Street, 7 of which were in response to the Facebook and Twitter posts
Residents that were in support of the all-way stop control at the intersection of Liverpool
Road and Wharf Street indicated the following:
• better for sightlines especially for motorists turning off Wharf Street as many
residents have reported having near misses
• an all-way stop will make crossing Liverpool Road safer for pedestrians
• will slow traffic making it safer for all users of the roadway
Residents that were opposed to the all-way stop control at the intersection of Liverpool
Road and Wharf Street indicated the following:
• the upcoming development at the old school site at the northeast corner of Liverpool
Road and Commerce Street will bring more traffic at the intersection of Liverpool
Road and Commerce Street
• does not make sense to put a stop sign for a road that is not a through street
• the all-way stop would be better served at Commerce Street since it is a through
street and is impacted by sightlines
• the all-way stop would be better served at Annland Street because it is frequented
by vehicles and cyclists that want to access the Waterfront Trail and park
• a roundabout would be a better alternative to an all-way stop
City of Pickering staff also sought comment from the Durham Regional Police Services
(DRPS) regarding an all-way stop control at the intersection of Liverpool Road and
Wharf Street. DRPS indicated that although unwarranted, they do not have concerns if

an all-way stop control is installed at the intersection of Liverpool Road and Wharf
Street to assist motorists with exiting from Wharf Street and to create a safe place for
pedestrians to cross.
In summary, based on the sightline concern, results from the community consultation
and to allow a safe pedestrian crossing for pedestrians due to the increased vehicle and
pedestrian volume from events at Pickering's Nautical Village, Engineering & Public
Works staff recommend the placement of an all-way stop control at the intersection of
Liverpool Road and Wharf Street.
The proposed all-way stop at the intersection of Liverpool and Wharf Street is illustrated
in Attachment 3.
The proposed amendment to the Traffic By-law 6604/05 is provided in Attachment 4.
