I saw these installed on the Arbutus Greenway today. This doesn't look in any form wheelchair, stroller, one wheel, skate board or bike friendly to me at all.
Is there any practical reason to build those barriers to justify making life harder for above mentioned groups?
Bollards can be an effective filter for those
Bollards completely block. Speed bumps slow down, or discourage if there are alternate faster paths. They have different purposes and goals.
These speedbumps are on a bike and pedestrian path. There shouldn't be any cars.
Good!
