How streets are classified
Functional classification sorts streets by the job they do: through movement, access, or both.

From the opening
Streets are classified by the job they are meant to do in a network, not only by how wide they look. Functional classification sorts them into types such as arterial, collector, and local, according to whether they mainly move traffic through or mainly give access to the land alongside. The opening covers arterials favor through movement, local streets favor access, and collectors link the two jobs.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
