The context for this phrase is in a list of kanji spellings (kanji with hiragana), thus the definitions are not provided.
Breaking the phrase into its components:
表す
- to reveal, show, display
通り
- avenue, street, way
Taking the second part (way) in a non-literal sense leads me to conclude the phrase means roughly,
the way shown
or more concisely as shown
Is my conclusion correct?
