NA traffic Engineers are still trying to wrap their brains around the concept of #edgeLaneRoads / can't find the right table for it in their highway design manual.

The right forces drivers to straddle the bumps and also share when needed. [cobbles between asphalt edge lanes]](https://cdn.masto.host/urbanistssocial/media_attachments/files/116/710/768/331/496/893/original/3a3a1466f5084e6f.png)

"...a great solution because we have some old trees and poles ... that don't allow for the construction of sidewalks"
"bike trails are great, but... in order to provide those safe places for people to get to where they want to get to outside of a vehicle" #transportation
"...wasn't a lot of room to widen this road...
keep the same amount of pavement"
typical summer day:
1300 people on bicycles
400 cars,
50 buses
"even if drivers aren't aware of that being the purpose, it's just sort of naturally happening" = infrastructure shapes behavior (aka #inducedDemand)
44% reduction in crashes vs the yellow centerline design on rural roads
The red bike lanes are kind of weird. Here red lanes are for transit, and private cars aren't allowed to drive in them (that rule gets broken a lot though).
@EverydayMoggie yes, US agencies are able to use green for bike lanes but none of them do enough of it to maintain dedicated asphalt machinery for that color like the Netherlands does.
