A diagram of a raised intersection from the National Association of City Transportation Officials — Here’s how Central Area Greenways describes it: “Raised intersections create a safe, slow-speed crossing and public space at minor intersections. Similar to speed humps, they reinforce slow speeds and encourage motorists to yield to people walking in the crosswalk.
Raised intersections are flush with the sidewalk and ensure that drivers traverse the crossing slowly. Crosswalks do not need to be marked unless they are not at grade with the sidewalk. ADA-compliant ramps and detector strips are always required.
Bollards along corners keep motorists from crossing into the pedestrian space. Bollards protect pedestrians from errant vehicles.”
