SUBJECT: |
Unionville
Traffic Management Plan |
|
|
|
RECOMMENDATION:
That the staff report entitled “Unionville Traffic
Management Plan” dated
And that the planned future road connections to Highway
7 from Markham Centre be aligned opposite Verclaire
Gate,
And that when the intersections are constructed, the
north leg of the intersections include appropriate geometric and landscaping
treatment to reflect the residential character of the roads on the north side
of Highway 7;
And that upon completion of the road connections,
staff implement the transportation management strategies as outlined in the
report entitled “Unionville Traffic Management Plan” prepared by BA Group dated
May, 2002.
And that the roads identified by the Unionville
Coalition, where there are concerns about speeding and safety, be considered by
the Markham Traffic Safety Committee as part of the Markham Safe Streets
Programme.
PURPOSE:
This report recommends the implementation of a traffic management strategy developed in consultation with members of the Unionville community in response to concerns about current and future traffic patterns.
BACKGROUND:
Residents in the Unionville community have expressed concerns about existing traffic conditions on several Town and Regional roads. The introduction of the Markham Centre secondary plan (OPA 21; approved in 1997), and current development appearing in Markham Centre have raised further issues with respect to the potential impact on the community as a result of potential traffic infiltration. In response to the concerns from the community staff held two workshops with members of the community in 2001/2002. These workshops identified the specific issues in the community and developed an approach to address these issues. A Traffic Consultant (BA Group) was retained to develop a traffic management plan in response to the community concerns.
The consultants report along
with staff recommendations was presented to the May 2002 Transportation
Committee meeting. Committee directed
staff to hold public meetings to receive input on the report recommendations. Two public meetings were held in January and
March of 2003. There were in excess of
200 people in attendance and the community at large raised a number of issues. One of the primary concerns was the alignment
of the roads from Markham Centre with Verclaire Gate,
As a result of these
meetings, there was a consensus that the collector roads from Markham Centre
should be aligned opposite Verclaire Gate,
DISCUSSION:
The
key issue identified by the Coalition is related to potential traffic
infiltration from Markham Centre.
Specifically there was a concern about the proposed alignment of roads
from Markham Centre with existing roads into Unionville. There are a number of criteria and tradeoffs
that were considered in evaluating the issue of alignment including impact on
transit service, accessibility to Markham Centre, convenience for residents,
and operational impacts on Highway 7.
Based on a detailed review of these criteria, it was determined that
aligning the roads is the preferred option. A key consideration was the fact that offset
roads would result in a number of additional signalized intersections along
Highway 7, increase operational concerns and still not prevent traffic from
infiltrating into the community. It was
determined that aligning the roads offered better opportunities to protect the
community since through traffic could be controlled more effectively by
prohibitions.
There
are various measures that can be implemented to protect a community from
traffic infiltration. It was determined
that focusing the solutions at the intersections along Highway 7 would provide
the most effective control of traffic volumes entering the Unionville
community. Controlling through traffic
across Highway 7 was also seen as the key solution. The consultant reviewed
various solutions implemented across the GTA and shared data that showed the
degree of compliance with through traffic prohibitions. The results showed that there is a high
degree of compliance to through traffic prohibitions when they are implemented
at signalized intersections. In all
cases, there was a greater than 95% compliance to the through traffic
prohibitions. These prohibitions range
from selected hours and direction, all day prohibitions and channelized islands
to physically restrict movements as shown in section 5.2 of Attachment B.
A staged approach is the best way
to implement the prohibitions
Through traffic prohibitions can result in significant impacts to the flexibility of residents to take advantage of new road links. Therefore, the consultant recommends a staged approach to implementing these restrictions based on monitoring of traffic volumes and confirmation of infiltration problems in the community. At this time, it is difficult to determine the degree of infiltration or the amount of traffic that will enter the Unionville community. Therefore, traffic conditions should be monitored and results should be documented before restrictions are implemented. There are readily available methods and techniques that can quantify infiltration problems that have been used by staff (ie license plate traces). Based on these studies, appropriate prohibitions can be implemented. The prohibitions can gradually be increased to offer more protection as studies warrant.
The north leg of the intersections
on Highway 7 will be designed to re enforce the residential character of the
community
South of Highway 7, Markham Centre
will promote a mixed-use development including residential, commercial, institutional and office land uses. As motorists travel north through Markham
Centre and cross Highway 7, it is important that the residential character of
the community north of Highway 7 is emphasized.
This can be done with appropriate geometric treatments, lane
configuration, and center medians and landscaping. It is recommended that these types of
treatments be included as part of the design for the Highway 7 intersections
and future developments proposed at
Other issues raised by the
Coalition
In addition to the key issue of infiltration, the Coalition also identified the following traffic matters:
·
Regional road capital programme – need to
accelerate the widening of Warden Avenue, Highway 7 and
· Sidewalks
· School traffic
· General speeding and operational problems on selected roadways
Staff has addressed these issues as noted below:
Regional road capital programme
In response to the circulation by the
Region on their road capital programme, staff has identified several road
projects to be accelerated.
Specifically,
Sidewalks
A sub-group of the Coalition met with
staff and identified
School Traffic
School traffic congestion was
identified at
General speeding and operational
concerns
In the fourth meeting with the
Coalition, four work groups were established to identify any speeding and
operational concerns in the community.
The work groups were requested to mark up an aerial photo of the
community and identify various streets (such as:
The Environmental Assessment (EA)
study for
Unionville Coalition Mandate
With respect to the initial concerns raised by the community about traffic infiltration, the Coalition has completed its mandate and agreed with the recommendations outlined in this report. There a number of major transportation initiatives underway adjacent to the Unionville community including rapid transit, road widenings, Anti-whistling studies, traffic calming, and the Markham Safe Streets programme. The Coalition stated that it would be productive to continue informal meetings with staff to share information and provide input early in the process. It is recommended that the Coalition meet on a semi-annual basis with the next meeting planned for the Fall of 2004.
