Subject:Traffic Concerns:

Lloyd Manor Road and North Heights Road

(Markland-Centennial)

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

North Heights Road; and

(2)the attached by-laws (Attachments No.1 and 2) receive Council approval.

Background:

The Transportation Services Division - District 2, received correspondences (Attachments No. 3 and 4) from Mr. Mitch Stambler, Manger - 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 Heights Road. 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, December 3, 1998 are summarized in the following table.

TIME	N/B	S/B	E/B	W/B	N/B+S/B TOTAL	TOTAL ENTERING INTERSECTION	BALANCE OF FLOW N-S/E-W
7-8 AM	37	26	25	14	63	102	62/38
8-9 AM	126	67	29	20	193	242	80/20
4-5 PM	57	64	21	21	121	163	74/26
5-6 PM	86	77	26	28	163	217	75/25
TOTAL	306	234	101	83	540	724	75/25
VEH/H	76	59	25	21	135	181	N/A

It is evident from the traffic count data that the heavier traffic flow at the intersection of LloydManorRoad 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.
