Your are entering a traffic calmed neighborhood!
The use of planters at streets as a strategy to prevent drivers from speeding might be an effective option to more disruptive or expensive alternatives like speed humps and traffic circles. In some cases planters are used to keep cars away from areas used by non-motorized vehicles like bicycle lanes.
Following are samples of the use of planters at streets found in the internet.
Vancouver, BC – dedicated bike lanes using planters as separators and barriers from article “A Family’s Vancouver Bicycle Cruise”
Graphic included in the article listed as route preference vs. route safety by UBC Cycling in Cities Research Program
Another example from Vancouver, BC from article about separated bikeways with great examples.
Great use of separator. Distance between them should be of consideration. Rectangular shape allows for narrow use of space.
Got to love the use of grading as a strategy to communicate with users.
New York City, NY – Pictures posted at article “Ideas for Downtown LA: What We Can Learn from NYC with Road Diets, Ped Plazas, Etc” good examples of what works or does not
Great use of bollards for identifying pedestrian area. Height of bollards might be of consideration due to distracted drivers and walkers. Note planters on left.
Combination of bollards and planters.
Planters to consider maintenance, a single planter might require less maintenance.
Rough rough rough.
From the UK and their creative ways to address speeding. Photo sample from article “Stop speeding… the DIY way: Plant pots, welcome mats and drawings slow cars” identifying “living spaces” vs. traffic corridors using planters to narrow width of travel lane and painted roadway. Additional article about this community project is found at Soft Paternalism blog.
A very interesting example from Camden Cyclists (London Cycling Campaign), Royal College Street “Space for Cycling” with many elements incorporated into the built environment – planters, low level separators, pavement markings.
Second photo shows very intense street design. The hard edges of the curbs are not too forgiving. Appear to be proper approach for directing users from one environment to another.
@daisyfroud twitted this fascinating overview of a Y-intersection from London indicating it is part of @sustrans project, a very nice alternative to traffic management.
Peopleforbikes.org shows a selection of “19 beautiful ways to protect bike lanes” some of them shown below. Use of low level spacers present a visibility concern for drivers, cyclists and walker.
Use of planters and bollards to divide uses of paths.
From Austria a unique use of a planter for traffic calming found at austriaroadways.blogspot.com
Example of a separated bike lane using planters and vertical delineators from this article on cycling dutch, Portland, Oregon.
A different approach to traffic calming, painting entire intersection part of a neighborhood project.
Local Austin example located on Guadalupe Street at the Strand, overview shows circles where planters are located.
Photo of Guadalupe Street showing the planters used to protect the bicycle lane listed as America’s best 10 bike lanes.
From livablecities.org a very interesting picture regarding revitalization of downtown shows the inclusion of a statue.
And positive reinforcement is often a great tool to reward those doing the neighborly thing as shown by this picture from fastcompany.net.
