DATE OF MEETING:

SUBJECT:

Birchview Lane/Kennedy Road Possible Signalization

 

 

 


 

RECOMMENDATION:

That the staff report dated May 16, 2005 entitled “Birchview Lane/Kennedy Road Possible Signalization” be received;

 

And that the requested traffic control signal at the intersection of Birchview Lane and Kennedy Road be considered in the context of the Town’s overall program of providing traffic control signals for unsignalized intersections (Attachment ‘A’), including consideration of warrant analysis through the annual Capital Budget Program commencing in 2006;

 

And that the Region’s proposal to cost share with the Town a possible traffic signal at Birchview Lane and Kennedy Road, on a 50%:50% basis , be included as a consideration in determining the relative priority for possible signalization, through the annual Capital Budget Program commencing in 2006;

 

And that the Region of York be requested to synchronize 16th Avenue signals to facilitate access to Aitken Circle;

 

And that the Region of York be requested to prepare a 10 year implementation plan for signalization of Regional intersections in Markham;

 

And that a copy of this report be sent to Brian Harrison, Director of Roads Transportation at the Region of York.

 

PURPOSE:

This report responds to a request from the Region to consider cost sharing for traffic signals at the Birchview Lane/Kennedy Road intersection to advance its signalization to 2006.

 

BACKGROUND:

Residents in the Aitken Circle subdivision have had concerns with respect to access to and from the Regional road system (see Attachment A) for a number of years.  Given the volumes and speeds on both 16th Avenue and Kennedy Road, residents have indicated that it is difficult to enter and exit their community from these roads.  As part of the approval of the Kylemore Homes development on the north side of 16th Avenue west of Kennedy Road, staff worked with residents, the developer and the Region to facilitate a solution.  A memo from planning staff was presented at the Committee of Whole meeting on December, 14, 2004 based on discussions with residents.  As noted on Attachment B, Council endorsed the recommendations and requested the Region to consider traffic control signals at an aligned intersection opposite Aitken Circle to provide access to both the Kylemore Homes application and the residents on Aitken Circle.  Council also requested the Region to consider a traffic control signal at the Birchview Lane/Kennedy Road intersection at their cost.

 

At their meeting on February 17, 2005 Regional Council approved signals on 16th Avenue approximately 260 metres west of Kennedy Road at the developers cost.  This location does not align with Aitken Circle.  Regional Council also recommended that a left turn lane and traffic control signals be considered at the Birchview Lane/Kennedy Road intersection subject to cost sharing arrangements with the Town of Markham as noted in Attachment C.

 

DISCUSSION:

Traffic signal warrants

Both the Town of Markham and the Region of York use traffic signal warrants to determine the technical justification for the installation of traffic control signals.  The use of signal warrants is an industry accepted practice to evaluate the technical need for signals and to prioritize installation.  Signal warrants evaluate traffic volumes and collision history to determine if signals are justified.  Typically, it is the traffic and pedestrian volume on the minor roadway that dictates whether a signal is warranted.   The Region of York undertook a warrant study at the Birchview Lane/Kennedy Road intersection in September, 2003.  The results showed that warrants 1 and 2 are satisfied 22% and 12% respectively and therefore the intersection fails to meet the minimum thresholds for the justification of traffic control signals. 

 

Although the study was undertaken in 2003, the results are considered valid since it is within the two year period that is considered acceptable for traffic studies.  While growth in the area has likely increased volumes on Kennedy Road, the critical volumes to meet the warrant are the minor street volumes from Birchview Lane.  Since the community to the west has been a stable residential community, it is unlikely there are changes in the volumes over the last two years that will affect a significant change in warrants.

 

Comparison to other intersections in Markham

The Region of York receives many requests for traffic control signals in Markham.  Attachment D shows the number of intersections where signals have been requested and the results of the warrant studies.  As shown on the table, there are a total of 40 intersections where signals are being considered which will increase as development continues in the OPA #5 areas.  Based on signal warrants, there are currently 36 intersections that would be ranked ahead of the Birchview Lane/Kennedy Road intersection.  It should be noted that this table only reflects the warrants.  The Region will undertake further technical assessments (i.e. proximity to other signals, sight lines and impacts to road operations) before signals are considered for installation. 

 

 

 

Birchview Lane/Kennedy Road  - installation costs and potential cost sharing

Town staff have met with Regional staff to discuss installation costs and potential for cost sharing as requested by Regional Council.  Regional staff have advised that signals cannot be supported without a left turn lane on Kennedy Road.  The total costs for both the left turn lane and the traffic control signal is approximately $300,000.  In the event Council considers approval of the project, Town and Regional staff agreed that it would be appropriate to consider a 50% cost sharing since the signal does not meet warrants.  The Town’s portion of the costs will need to be funded from tax rate.  The approved 2005 budget does not have any allowances for this project.

 

Signals for Kylemore site could improve egress from Aitken Circle

As noted earlier, the Region approved installation of signals 260 metres west of Kennedy Road on 16th Avenue at the planned access for the Kylemore application.  When built this will result in a signal approximately 100 metres west of Aitken Circle.  The new signal combined with synchronizing the existing signal at Kennedy Road should help to improve conditions for residents exiting from Aitken Circle.  The new signal should be coordinated with the signal at Kennedy Road.  When both signals stop traffic along 16th Avenue, it will offer more gap opportunities for residents to exit onto 16th Avenue.

The Region will minimize overnight operations in residential areas and will focus evening and overnight operations in commercial areas.

 

CONCLUSIONS:

 

Given the low threshold in warrants, the high costs of signal installation and the number of other higher priority locations in Markham, staff recommend the signal at the Birchview Lane/Kennedy Road intersection be considered as part of the 2006 Capital Budget program and a 10 year implementation plan for Regional intersection signalization.  As part of the installation of the signals on 16th Avenue, the Region of York should synchronize signals to facilitate access to Aitken Circle.  Signal installations should be prioritized based upon the warrants.

 

FINANCIAL CONSIDERATIONS:

There are no costs associated with staff recommendations in this report.  In the event Council approves the potential cost sharing of this project, funding in the amount of approximately $150,000 will need to be allocated to the 2006 operating budget from the tax rate.
