PBOT has been using a new type of speed bump on our neighborhood greenways and we're interested in your opinion.
Have you ridden on a neighborhood greenway with bike-friendly speed bumps? If so, then we want to know what you think of them.
Portland has more than 110 miles of neighborhood greenways. For decades we've used speed bumps to ensure that people driving on these shared street bikeways go slowly--ideally 20 mph or less. While the speed bumps are effective at reducing car speeds, we've also heard complaints about the "bump" they create for people bicycling.
We've developed "firetruck-friendly bumps" with pass-through channels for firetruck tires. That design allows us to calm traffic on emergency response routes without slowing the trucks. We recognized we could do something similar for people biking. Hence, the bike-friendly speed bumps.
We've begun testing these on a number of neighborhood greenways (you can see a map of locations at the below, linked website). Now, we want to hear from you. We've launched a public survey to garner feedback about these bumps and to inform if and how these bike-friendly bumps will be deployed in the future. Follow this link to our bike-friendly bump website to learn more and to take the survey.
Over the next few months we'll gather public feedback, assess their effectiveness at slowing cars and publish a report about our findings.
