Often, the 名詞（めいし） (noun) とおり carries the meaning of ‘in that way’, or ‘just like that’. In its kanji form, とおり will be written as 通（とお）り, and literally means ‘street’, or ‘way’. However, it is regularly used to indicate the level of ‘sameness’ one thing has with another. This ‘sameness’ meaning appears when とおり is used as a 接尾語（せつびご） (suffix).
とおり (or どおり) may be used with verbs or nouns. In the case of verbs, it is common to see it being used after both the plain form, and the simple-past form.

• お客様（きゃくさま）のおっしゃる通（とお）りです。
  Honored guest, the thing you say is precisely correct. (That’s exactly right)
• 彼（かれ）は僕（ぼく）の思（おも）った通（とお）りの時間（じかん）に帰（かえ）ってきた。
  Just as I expected, he came back when I thought he would come back.

For nouns, どおり is far more frequently used when following the noun directly, while とおり will be used when the 格助詞（かくじょし） (case marking particle) の comes between the noun and とおり.

• 計画（けいかく）どおりに進（すす）めて行（い）きます。
  We will continue as the plan suggests.
• ご覧（らん）の通（とお）り、私（わたし）の手（て）には何（なに）もありません。
  As you can see, I have nothing in my hands.

While both of these structures may be used interchangeably, どおり is more common, especially in speech.
