Curb extensions visually and physically narrow the roadway, creating safer and shorter crossings for pedestrians. They increase the overall visibility of pedestrians by aligning them with the parking lane--and increase available space for street furniture, benches, plantings, and street trees. In the Urban Street Design Guide, we provide guidance for installing curb extensions (including conventional curb extensions, pinchpoints, gateways, chicanes, and bus bulbs).

I'm not sure I see the value of 2 lanes of on-street parking that are creating the need for curb extensions though
NACTO (National Association of City Transportation Officials) These 👌 but instead have THE CAR come up to the pedestrian level and continue the sidewalk as a level crossing

This is a very interesting. Nice illustration. At Trash Scouts, we help business get the trash bins to the curb for pickup days, we are definitely struggling to find more creative ways place dumpsters curbside and not block parking, bike lanes or any passage for pedestrians. Not sure how the need to safely access the trash for waste workers are being factored in

Given solo and duo occupant driving preference, narrowing cars, lanes, and parking spaces will also enhance street safety and pleasure: https://youtu.be/-Lj_eE7wFPY?si=N0sfsw8UKBnOOHdM #ThinMobility

Hi! Love your guides, they are truly amazing. Do you think there might be another update in future to the Global Street Design Guide with regards to cycling? (Instead of cycling being a subject of a separate guide). The bicycle lane in this picture does not seem be the safest option, as it leaves the risk of dooring in place. Many thanks!

I’d love to see new placemaking space named as a goal rather than a side benefit of transportation improvements. When the goal is a livable city, let’s prioritize people in place: enjoyable walking/rolling and welcoming outdoor environments where we can linger.
Making them raised pedestrian crossings improves safety further. Eminently possible in an urban environment.

Great thoughts but the idea of vegetation obscuring drivers view of pedestrians crossing could be an issue.

1moWhat are best practices for mitigating drainage problems caused by bump outs downstream of gutter flow? Bringing the curb line in often creates a new low point where the curb transition ties to the existing curb line. Additionally, the additional sidewalk area often slopes back to the old curb line without significant site re-grading, causing ponding and PROWAG issues. We have tried a variety of solutions, but none feel like a home run: trench drains, bioswales, etc.
