Traffic Concerns: Lloyd Manor Road and North Heights Road
(Markland-Centennial)
The Etobicoke Community Council recommends the adoption of the following report
(February 17, 1999) from the Director, Transportation Services, District 2:
Purpose:
To propose the installation of all-way stop controls at the intersection of Lloyd Manor Road
and North Heights Road.
Funding Sources:
The funds associated with the installation of regulatory signs are contained in the
Transportation Service Division's Operating Budget.
Recommendations:
It is recommended that:
(1)all-way stop controls be installed at the intersection of Lloyd Manor Road and
NorthHeightsRoad; and
(2)the attached by-laws (Attachments Nos. 1 and 2) receive Council approval.
Background:
The Transportation Services Division - District 2, received correspondence
(AttachmentsNos.3and4) from Mr. Mitch Stambler, Manager - Service Planning, Toronto
Transit Commission(TTC), and Mr. Arthur Keyes, 136 Prince George Drive, requesting an
investigation into the feasibility of installing all-way stop controls at the intersection of Lloyd
Manor Road and North HeightsRoad. These requests are the result of the complainants'
concerns with respect to the geometry of the intersection of Lloyd Manor Road and
NorthHeights Road. A map of the area is Attachment No.5.
The intersection of Lloyd Manor Road and North Heights is classified as a skewed (oblique)
type, meaning the cross-roads intersect each other at an angle of 70 degrees or less. Site lines,
as a result of this intersection configuration, are less than adequate for northbound and
southbound motorists at the approaches to NorthHeights Road.
Lloyd Manor Road, the stop street, is classified as a secondary collector roadway. The legal
speed limit on this roadway is 50 km/h. TTC bus stops are located on Lloyd Manor Road at
the south-east and north-west corners of Lloyd Manor Road and North Heights Road. North
Heights Road is classified as a local roadway with a legal speed limit of 50 km/h.
Comments and Discussion:
To assess traffic conditions at the intersection, the following information was obtained:
(1)manual approach counts conducted at the intersection of Lloyd Manor Road and
NorthHeights Road;
(2)review of the three year collision history; and
(3)intersection description, including existing parking restrictions, sidewalks and adjacent
land use.
The following warrants need to be met in order to justify the installation of all-way stop
controls on roads and streets considered to be neither arterial, nor major collector streets:
(a)total vehicle volume on all intersection approaches must exceed 350 for the highest hour
recorded; and
(b)a volume split should not exceed 65/35 for a four-way control.
(1)Manual Turning Movement Count.
The results of the all-way stop study conducted at Lloyd Manor Road and North Heights Road
on Thursday,December3,1998, are summarized in the following table:

It is evident from the traffic count data that the heavier traffic flow at the intersection of Lloyd
Manor Road and North Heights Road is on the stop street (Lloyd Manor Road). Although the
total intersection volume fails to meet the volume warrant, the installation of all-way stop
controls at this intersection would improve traffic safety, given the geometry of this
intersection.
(2)Collision Analysis.
A review of the collision history for the last three years reveals seven angle type collisions
have occurred at the intersection of Lloyd Manor Road and North Heights Road. One of these
collisions did involve a TTC bus.
(3)Intersection Description.
Parking Regulations: Three hours maximum on both roadways.
Lane Configuration: One lane in each direction.
Sidewalks:Both sides of Lloyd Manor Road and the south side of North Heights Road
Land Use:R2 Residential (Second Density)
Conclusions:
Traffic volumes at the intersection of Lloyd Manor Road and North Heights Road do not meet
the minimum requirements of the warrants for all-way stop controls. However, given the
geometry and collision history of the intersection, the installation of all-way stop controls
would improve traffic safety.
