"cul-de-sac"的定义和意义

What is a "cul-de-sac"?

A cul-de-sac is a dead-end street or road that is designed with a circular or rounded turning area at the end, allowing vehicles to turn around easily. It is typically found in residential neighborhoods and is often quieter and safer than other streets due to the lack of passing traffic. Cul-de-sacs are popular in suburban areas because they provide more privacy for residents and reduce the amount of passing cars. The design of a cul-de-sac can also help in managing traffic flow within a neighborhood.
