I've previously advocated for angled parking spots rather than ones at 90 degrees (Hospital Entrances & The Patient Experience - May 10, 2016).
This post discusses a relatively new parking spot design that combines my recent obsession with back-in parking with the previous benefits of angled parking: it's called back-in angle parking or reverse angle parking.
Review the image below to see how this type of parking works. The video happens to also be from my hometown of Winnipeg.
I was curious to see the space difference required for 90-degree parking layouts vs angled parking. This parking plan demonstrates that 60-degree angled parking with a one-way driving aisle requires only slightly more space than the regular 90-degree layout.
