A/B Street is a traffic simulator that models Seattle's actual traffic, using real Seattle traffic data, created by Dustin Carlino, whose "ultimate goal is for your changes to become a real proposal for adjusting Seattle's infrastructure."

The idea is to feed residents' lived experience of traffic dysfunctions ("the one left turn lane that always backs up or a certain set of poorly timed walk signals") into planning discussions.


Your changes to Seattle traffic rules ripple out through pedestrians, public transit, cyclists and private vehicles, which you can both visualize and quantify through a dashboard.

Carlino has a standing offer to help you recreate this for your city: "If you want to bring this to your city or if you're skilled in design, traffic simulation, data visualization, or civic/government outreach, please contact Dustin Carlino at"
