I wrote a blog post about my learnings there - "Engineering over enforcement":
> Enforcement philosophy is rooted in the idea that behavior can be controlled by threatening punishments. Engineering philosophy believes that infrastructure can be designed to incentivize desired behavior. When Oslo sought to reduce pedestrian deaths, it turned to engineers.
> [ . . .] Intersections are one small example where philosophies can diverge. But, as I learned in Oslo, engineers have a whole toolkit of methods to make cities safer. Bumping out a curb slows down turning speeds and protects pedestrians. Bike lanes can be safer by being raised above the street instead of relying on a painted barrier. Limiting how far cars can see ahead of them slows them down. Behavior can be designed rather than just enforced, and in aggregate these small changes can make a city safer.
