Ramps
Ramps are not very commonly used in Thailand. You will typically only find them where 2 roads classified as freeways meet (Federal 1-digit Highways, Motorways and Express ways).
For guidance on when to use ramps, please read here.
Naming should be done according to this article.
Most other road connections are formed using At Grade Connectors
