Traffic calming proposal
Traffic calming definition
“Traffic calming is the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior, and improve conditions for non-motorized street users.” ~ Traffic Calming: State of the Practice (ITE/FHWA, 1999)
On neighborhood streets the concerns are usually about speeding, cut-through traffic, or failing to yield or stop. If we can validate the concerns, the tools we have available can address the concerns, and we have the resources to install the tool, we will implement low cost and temporary changes. These tools include traffic circles, speed humps, bump outs, and other changes to the street that encourage drivers to slow down and drive more carefully. You can learn about these tools in appendix F of the draft document.
How to request traffic calming
You should call 311 to let us know about traffic safety issues and request traffic calming. We ask that you explain the issues using as much detail as possible, instead of just asking for a specific solution, so that we can evaluate the issue and propose possible solutions. We received about 2,500 requests each year, and respond in the order we receive them. We ask for your patience while we look at the details of each issue, as the number of requests has greatly increased. We are proposing a new process that will go into effect in 2022, and will make the request process work more smoothly.
The proposed process
We want your input on a new process we are proposing to address traffic safety concerns and traffic calming requests.
The proposed process for neighborhood traffic calming seeks to provide a process that
- better considers the overall network
- is data-driven and transparent
- is more equitable
We received nearly 200 public comments on the proposed draft. We will review those comments and make changes to the proposed process. We will then share updates on this webpage.
You will find details about the proposal including the streets that are eligible for this process, an application form, an update toolbox, information about how we rank the applications, and a proposed timeline:
