Thanks to a great walking salon up historic 16th Street, NW in Washington, DC, I found out that traffic engineering came from a group of passionate people – some who didn’t even own cars – with influence from agriculture, public works, and a bunch of other places.
When traffic was becoming a thing, there were a small group of people interested in pedestrian safety, before it was fashionable, the ancestors (I’ll say) of today’s Vision Zero.
