Every ward in the City of Ottawa is given a budget of $40,000/year (potentially increasing in 2019 subject to approval of the City budget) to invest in Temporary Traffic Calming (TTC) measures throughout the community. You may have noticed some of these measures on local streets. There are a variety of options that are proven effective in improving driver behaviour and reducing speeds:
  • Centre line flex stakes: make the roadway appear narrower, naturally encouraging drivers to stay in the proper lane and reduce speed. Used alone, this measure can increase compliance by up to 7.3%. Used in conjunction with side delineators (like on Coronation Avenue), compliance can increase by up to 23%
  • Speed display boards: show drivers the speed at which they are travelling, reminding them to slow down
  • Speed pavement markings and school zone markings: grab the attention of drivers and remind them to correct their behaviour. Have increased compliance by up to 10.8%
  • Permanent “Slow down for us” signs: grab the attention of drivers and remind them to correct their behaviour. Have increased compliance by up to 6.4%
  • A relatively new measure available to us is the 3D speed hump, like the one on Othello. Similar to a speed pavement marking, it grabs the attention of passing vehicles and serves as a reminder to slow down. These markings may increase compliance by up to 10%
Each street is assessed individually and TTC measures are tailored to specific needs as some might be more effective than others in particular areas. There are also restraints as to where certain measures can be installed. For example, flex stakes are not recommended on streets that do not have sidewalks, because sometimes drivers react by veering widely around the stake. We work closely with our partners in TTC and rely on their expertise in making these decisions.

In Alta Vista, the locations of TTC measures are always chosen based on resident input and feedback. Every single measure you see around Alta Vista started with a request or a concern from a resident. No one knows your street better than you do, that is why I need your help determining where TTC measures are needed. If you live on or know of a street that may be in need of traffic calming, please call or email my office by January 30th to help us compile our list of spring measures.
