Traffic Calming Demonstration Project
November 2023
Speeding traffic, stop sign running, and aggressive and/or distracted driving have long been top concerns of our residents. We worked with the City of Columbia to trial this curb extension project on Park Street, which has proved to be an effective traffic calming mechanism in communities across the country.
Curb extensions, also known as bump outs, are designed to slow traffic by both visually & physically narrowing intersections.
This also allows us to:
Move the stop signs closer to the travel lanes,
Shorten the distance of crosswalks, and
Improve pedestrian visibility.
Example of a permanent bump out
We know the plastic bollards aren’t the prettiest – and this is only designed as a temporary demonstration project, so that we can evaluate its effectiveness and gather neighborhood feedback.
If we find them effective, we’ll eventually replace them with proper curb extensions that can be planted & beautified!
