Date of Report: 2007 June 13
Report No.: DTS 07-078
Subject: TRAFFIC CALMING -CHANDLER DRIVE
RECOMMENDATIONS:
That a raised pedestrian crosswalk with curb extensions be installed on Chandler Drive
at the north property limit of the Chandler-Mowat Community Centre, and further;
That an intersection narrowing be installed on Chandler Drive at Elmsdale Drive, and
further;
That two (2} speed humps be installed on Chandler Drive between Elmsdale Drive and
Strasburg Road.
BACKGROUND:
The existing City of Kitchener traffic calming policy was adopted by Council in August 2004
(DTS O4-125). The traffic calming policy outlines a number of evaluation criteria that provide a
fair and consistent review of streets and communities, while defining and prioritizing the
individual streets and/or communities that are most in need of traffic calming, from a traffic
safety perspective.
In November 2005, Council approved DTS Report 05-187 - "Traffic Calming Priority - 2006",
which recommended that a traffic calming study be conducted for Chandler Drive, as well as for
Chopin Drive and Bradley Drive.
Transportation Planning has received requests from residents of the Laurentian Hills
Community on numerous occasions in the past to review the existing traffic conditions on
Chandler Drive. According to the concerns indicated, traffic is using Chandler Drive as a short-cut
to avoid congestion on Ottawa Street South, and that this traffic is speeding, creating concerns
regarding pedestrian safety.
In response to these requests, the City of Kitchener has reviewed the existing traffic conditions on
Chandler Drive and initiated a formal Traffic Calming Review. Undertaking a traffic calming
review for a project of this scale and nature is considered good municipal planning and allows the
City and stakeholders to understand all of the impacts, constraints and opportunities associated
with any traffic calming measures.
REPORT
Chandler Drive runs from Strasburg Road to its south limit, south of Mowat Boulevard, and is
designated as a local roadway. The function of Chandler Drive is to generally serve only the
abutting properties and is not intended to carry through traffic. Chandler Drive provides direct
access to the Chandler-Mowat Community Centre, the City of Kitchener Operations Yard at 82
Chandler Drive, as well as the Grand River Transit Strasburg Operations Yard. The unposted
speed limit is 50 km/h as outlined within the City of Kitchener Uniform Traffic Control By-law
2000-159.
On March 22, 2006 our study team held its first public meeting to discuss traffic issues and
concerns on Chandler Drive and possible approaches to developing solutions. Traffic volume,
traffic speeds and pedestrian safety were identified as the main concerns. The existing traffic
conditions as discussed in the first meeting are as follows:
Automated Volume & Speed Studies
From September 25 -October 1, 2004, and from July 2 -July 8, 2005, volume and speed
studies were conducted on Chandler Drive at three separate locations. The following data was
recorded:
Location AADT 85t Percentile
Chandler Drive between
Strasburg Road & Woodfern Northbound 1211 veh/day 63 km/hr
Court Southbound 1381 veh/day 59 km/hr
Chandler Drive Between
Bonfield Place & Elmsdale Northbound 1245 veh/day 64 Km/hr
Drive Southbound 1070 veh/day 60 km/hr
Chandler Drive Between
Mowat Boulevard & Leanest Northbound 1232 veh/day 62 km/hr
Court Southbound 1189 veh/day 62 km/hr
Traffic volumes are minimally above the expected range for a local roadway, however Chandler
Drive does provide a significant element of medium and high density residential uses that can
generate significant traffic volumes. Speeds are higher than anticipated for a roadway with
similar geometrics.

Collision Analysis
The collision history was reviewed for Chandler Drive. There were 28 reported collisions on
Chandler Drive from January 2001 to December 2005. Collision types included failure to yield
right-of-way, loss of control, parked vehicles, as well as two collisions involving pedestrians.
This collision history does not show a clear, identifiable collision trend.
Origin /Destination Study
An origin /destination study was conducted for Chandler Drive on October 1, 2004. This
licence plate trace study was conducted during the time periods of 11:30 am to 1:30 pm and
4:00 pm to 7:00 pm, recognizing when traffic to the area's new commercial plaza is greatest, in
combination with on-street peak hour traffic conditions.
This study determined the percentage of vehicles that are using Chandler Drive, however, are
not destined to or from Chandler Drive. Results of this study are as follows:
11:30 am to 1:30 pm 11-13% through traffic on Chandler Drive
4:00 pm to 7:00 pm 18% through traffic on Chandler Drive
These study results indicate that a portion of traffic destined for the new commercial plaza is
using Chandler Drive as an alternative to busier, more congested conditions on Ottawa Street
South.
Community Response
Response received following the first public meeting did not indicate a clear traffic calming
approach preferred. 65 responses were received from area residents, with issues raised
including volume of traffic, speed of vehicles and pedestrian safety.
Based on the analysis of existing traffic, public input and the City of Kitchener's Traffic Calming
Policy, five potential alternatives, comprised of a number of measures of varying degree, were
considered, including "do nothing" the "do nothing" alternative is required as part of any formal
traffic calming review). These alternatives were then evaluated by the project team based on a
number of social, natural and economic criteria to develop a preferred option. The attached
chart outlines the evaluation of the criteria. The following is a list of the alternatives considered:
A series of three chicanes -chicanes are a series of horizontal deflections that cause a
weaving pattern forcing vehicles to slow down and weave between the chicanes.
A series of three speed humps -speed humps are vertical deflections in the roadway
that force vehicles to slow down to negotiate the humps.
Two raised intersections and one road narrowing -raised intersections are vertical
deflections of an entire intersection that force vehicles to slow down to negotiate the
intersection, while a road narrowing reduces a driver's comfort level, thereby reducing
speeds.
A series of two speeds humps, one intersection narrowing, and one raised crosswalk -
raised crosswalks are vertical deflections in the roadway, along with a narrowed
roadway, that forces vehicles to slow down when negotiating the crosswalk.
Do nothing.

A second public meeting was held on November 29, 2006 to present the alternatives, the
advantages and disadvantages of each alternative, and to present the preferred alternative as
determined by the steering committee. Attendees were asked to provide any comments before
a recommended plan was developed.
On May 14, 2007, Transportation Planning mailed a survey to all residents/property owners that
abut or are adjacent to Chandler Drive, as well as to any other parties that had indicated interest
in the study, outlining the recommended plan.
The intent of the survey was to determine if there is sufficient support for the implementation of
the recommended measures. As per the City of Kitchener Traffic Calming policy, a minimum of
50% of directly affected residents/property owners must respond to the survey and 60% of the
respondents must support the recommended plan, in order for any further consideration of the
plan.
There were a total of 608 properties surveyed within the boundaries of the study area. The
results of the survey are as follows:
In favour of the recommended plan 94 (90%)
Opposed to the recommended plan 11 (10%)
Total 105 out of 608 responded (17%)
Therefore the Chandler Drive traffic calming study has not met the minimum required
community support as outlined in the City of Kitchener Traffic Calming policy. However, a
significant portion of the residents in this area live in higher density rental properties, where
turnover is typically much greater and residents tend to take less "ownership" of the municipal
issues in their neighbourhood. Additionally, this area is populated with a great number of
residents new to Canada, where English is not the first language spoken. As a result, staff are
of the opinion that this low response rate is not necessarily indicative of a lack of interest by the
residents.
The measures recommended for Chandler Drive can be considered good traffic engineering in
that they address the concerns regarding speeding traffic and pedestrian safety. Therefore,
while the minimum public input requirement was not met through this process, staff
recommends that the proposed speed humps, road narrowing and raised crosswalk be
implemented on Chandler Drive.
As part of the traffic calming study the recommended traffic calming plan was distributed to all
affected agencies for their comments/concerns. Responses were received from The Region of
Waterloo, Waterloo Regional Police Services, Grand River Transit, City of Kitchener Operations
Services and City of Kitchener Fire Services. The following is a synopsis of their comments:
Waterloo Regional Police Services - No concerns.
Grand River Transit -Concerns with crossing the centre line on Chandler Drive when
turning right from Elmsdale Drive.
City of Kitchener Operations -Concerns with icing at the base of vertical deflections
which results in extra salting at the base of any vertical deflection. The curb extensions
are difficult to plough around and will slow ploughing in the area. This extra attention
required will add to the cost and time taken to conduct winter maintenance.

Emergency Medical Services - No concerns.
City of Kitchener Fire Services -Opposed to any vertical deflection due to increased
response times and concerns regarding vehicle maintenance. Additionally, Fire advise
that all roadways be designed to meet the requirements of the OBC Ontario Building
Code) and the City of Kitchener Urban Design Guideline Manual. Further, Fire
Headquarters is located on Strasburg Road near Chandler Drive. Accordingly, in the
event of a situation at the main Fire access intersection of Strasburg Road and Ottawa
Street, Chandler Drive is used as an alternate route.
All measures proposed for traffic calming on Chandler Drive meet the requirements of the OBC
and City's Urban Design Guideline Manual.
Should Council endorse the Recommended Plan, all proposed traffic calming measures are
expected to be installed in the summer/fall of 2007.
FINANCIAL IMPLICATIONS:
The cost to install a raised pedestrian crosswalk, road narrowing and two (2) speed humps is
approximately $35,000. This cost will be taken from the existing traffic calming budget.
COMMUNICATIONS:
This project has had extensive public involvement and communication. It has included two
public information centres, newspaper notices, a comment form and a survey, as well as the
use of web-based communication through the City's website.
CONCLUSION:
The recommended plan, which recommends the installation of two (2) speed humps, one (1)
road narrowing and one (1) raised crosswalk, provides the best technical solution to problems
indicated through the traffic calming study. While resident input did not meet the minimum policy
requirement, those that did respond are in majority support of our proposal. Transportation
Planning feels that the recommendations improve general traffic conditions, as well as improved
pedestrian safety specifically for the Chandler-Mowat Community Centre, as well as for all users
of Chandler Drive.
