Shortly put:
A traffic design philosophy where officially the goal is to separate cars and pedestrians fully, building cities so that you can walk between places completely without being obstructed by lanes built for cars in any manner.
An important part of the SCAFT design philosophy is also that moving outdoors is important. For that reason, a SCAFT-designed area has circular paths for jogging, and bicycle paths are designed to make small detours in order to go over hills instead of past them, so that bicycling would be a more efficient form of physical excercise.

A core thought enshrined in SCAFT is that moving within one's own neighbourhood happens exclusively by walking and moving between neighbourhoods happens exclusively by car or public transportation.
Walking and bicycling are seen purely as forms of physical excercise; a hobby. The idea that you could ride a bicycle to work is diametrically opposed to the SCAFT design philosophy.

The effect has been that cars have relatively fast roads to use for getting from district to another and are fully separated from other forms of traffic. In practical terms this is a system for reducing all distractions to driving your private car within urban city structure. Since inter-district traffic does not happen by muscle power, those are given very little thought. This has caused a lot of deaths when car drivers used to driving in their own peace have not remembered to think about existence of bicycles when turning. Their ways are elsewhere and very important thoroughfares cross the cars' routes in very unintuitive places. Because the bicycle routes were never designed as a sensible network and bikes take routes over points where two districts' physical excercise infrastructures intersect each other.
