We'd like to hear what you have to say

On June 19, 20 and 21, 2018 we held information sessions to gather public input and discuss ideas, concerns and potential treatments for the 20 school zones that are included in the study.

If you were not able to attend any of the meetings in person, we'd still like to hear from you and we welcome your input via email.

What is traffic calming?

Traffic calming is a measure available to the town that can be used to mitigate speeding in instances where higher speeds have been observed and conventional methods of speed deterrence, such as enforcement and education, have not been effective. Some examples of include line markings, radar speed display signs, speed cushions and roundabouts.

How does a roadway qualify for traffic calming?

To initiate a traffic calming process a candidate location must first satisfy Warrant 1 – 85th Percentile Speed. Warrant 1 is obtained following a 48-hour speed survey conducted either in the spring and/or fall.

Warrant 1 requires 15 per cent of motorists to be driving at a speed greater than:

  • 10 km/h over for a posted speed of 40 km/h
  • 11 km/h over for a posted speed of 50 km/h
  • 12 km/h over for a posted speed of 60 km/h

If Warrant 1 is met, locations will first receive a Radar Speed Display Sign (RSDS) unit. If speeds remain above the threshold after the RSDS is removed, the location then qualifies for line markings. If line markings are already present, the town will directly proceed to implement physical traffic calming measures.

Passive traffic calming examples

Radar speed display signs

  • Displays speed of vehicle to its driver via an electronic display.
  • Provides driver with feedback regarding vehicle operating speed.
  • Can be permanently or temporarily installed.


Other passive calming techniques

  • Pavement markings on roadway used to define space for vehicles (edge lines, cycle lanes)
  • Clearly indicate driving space.
  • Narrow the driving lanes to encourage drivers to slow down.

Physical traffic calming examples

Raised crosswalk

  • A marked pedestrian crosswalk at an intersection or mid-block location constructed at a higher elevation than the adjacent roadway.
  • Delineates the pedestrian and automobile space.

Curb extension

  • Widening of curb into roadway, typically at intersections to reduce vehicle speeds.
  • Slows vehicles making turns and reduces crossing distance for pedestrians.
  • Provides opportunity for visual/landscape enhancement.


  • A roundabout is a circular intersection where drivers travel counter-clockwise around a centre island.
  • Aesthetically pleasing, while enhancing safety.
  • Already implemented in several locations in Oakville.

Raised centre median

  • An elevated median constructed in the centre of the roadway.
  • Helps slow traffic without reducing capacity, while providing visual aesthetic.
  • Reduction in pedestrian-vehicle conflict.

Concrete speed cushion

  • The Town of Oakville has implemented this measure in most school zones in the town.
  • Features a centre 'knock-down' post allowing emergency vehicles to pass.
  • Slows passenger vehicles via a small speed hump on roadway.
  • Designed to accommodate wide wheel base of emergency vehicles (easy passage).
  • Use on local & collector roads.


  • Two or more alternating curb extensions that narrow a two-lane road to a one-lane road for a short distance.
  • Requires drivers to slow down and drive around them in a serpentine pattern.
  • Used on local and minor roadways not designated for transit or emergency vehicles.

2017/2018 physical traffic calming projects

Three roadways qualified for physical traffic calming in 2017.

  • Pinegrove Road
  • Ridge Drive
  • Great Lakes Boulevard

Pinegrove Road

Traffic calming in Pinegrove Road was driven by ongoing concerns from local residents regarding speeding and aggressive driving on their street. A speed survey conducted by the town confirmed that speeding was an ongoing issue. The speed survey also found that traffic volumes on Pinegrove Road were substantially higher than what is expected for a local road.

Through the public consultation process, residents voted in favour of physical traffic calming and selected speed cushions as the preferred option. Thirteen speed cushions were implemented on Pinegrove Road in November 2018, from Fourth Line to Warwick Avenue. Review the current speed cushion layout on Pinegrove Road.

In early 2019, we will be looking for feedback from residents on Pinegrove Road regarding the current layout and design of the speed cushions. Any future design modifications will be communicated with area residents prior to any changes being made.

Pinegrove Road is a local road intended to carry local traffic. Traffic calming on Pinegrove Road was driven by ongoing concerns from residents regarding speeding and aggressive driving on their street. As well as speeding, the speed survey found that traffic volumes on Pinegrove Road were substantially higher than what is expected for a local road, suggesting that motorists from outside the area were using the street to quickly bypass the major roads intended for through traffic. Speed cushions help deter through traffic from local roads and divert it to the collector roads, keeping residential areas safe.

To be effective, speed cushions are placed between 80-120 metres apart. This spacing prevents vehicles from speeding between the cushions and defeating their purpose. Pinegrove Road is 1,350 metres long, resulting in 13 cushions.

Speed cushions are built to the town’s specifications following the Transportation Association of Canada (TAC) Traffic Calming Guidelines. Other municipalities (i.e. City of Burlington, City of London) follow the same design.

Unfortunately, people speed and studies and past experiences show that lowering the speed limit alone does not have considerable impact on the operating speeds of road users. 

A stop sign is not a speed control device; it is a traffic control measure to assign the right-of-way at intersections. Intersections at Pinegrove/Warminster and Pinegrove/Maplehurst were reviewed to see if all-way stop signs were required. Neither of them met the all-way stop warrant criteria.

The yellow bollards are markers to help guide emergency vehicles around the speed cushions in an emergency. They are flexible and easily bend out of the way of the emergency vehicle. We’ve noticed that some have been removed or vandalised and we will be replacing them in the coming weeks. We are working with the Halton Regional Police to monitor this situation.

In 2016 – Following concerns from residents, a speed survey was conducted on Pinegrove Road. Average operating speeds were found to be 59 km/hour in the westbound direction and 62 km/hour in the eastbound. Based on the 62 km/hour speed results, physical traffic calming was warranted.

MAY 2017 – A traffic calming survey was distributed to residents of Pinegrove Road asking them if they supported physical traffic calming on their street. The majority of respondents living on Pinegrove Road voted in favour of traffic calming.

NOVEMBER 2017 – An invitation to a public information meeting was sent to residents. Two traffic calming designs were presented at the meeting: speed cushions and chicanes (curb extensions that periodically narrow a two-lane road to a one-lane road). Speed cushions were selected as the preferred option. Residents were notified of the decision to proceed with the speed cushion design.

OCTOBER 2018 – Notice was sent to residents about the start of construction of the speed cushions.

Consistent with TAC guidelines, the town’s traffic calming process includes a post-implementation review and possible modification or removal of the traffic calming measures.

The town continues to welcome input from area residents. As the speed cushions were installed at the request of the residents living on Pinegrove Road, the town will be surveying these residents in early 2019 to gather their feedback on the current layout.  

Any planned changes to the cushion design or layout will be shared with area residents, prior to any changes being made.

Ridge Drive

Residents of Ridge Drive also voted in favour of speed cushions, as the most preferred physical traffic calming measure. Three sets of speed cushions were implemented from Sixth Line to Kent Avenue in the fall of 2018. Review the current speed cushion layout on Ridge Drive.

An additional speed survey will be collected in the spring of 2019 to measure the effectiveness of the imiplemented measure.

Great Lakes Boulevard

Great Lakes Boulevard traffic calming study is currently underway. Proposed treatments include raised centre median, curb extension, pedestrian crossover and roundabout. The study is anticipated to be completed in spring 2019.
