What is a col-de-sac commonly known as?

A col-de-sac is commonly known as a dead-end street with a turnaround, which aligns with the definition of this term in urban planning and road design. Typically found in residential areas, a col-de-sac is characterized by being closed at one end, allowing vehicles to turn around efficiently instead of having to backtrack. This design promotes a quieter, less trafficked environment, making it an appealing feature for neighborhoods.

The turnaround aspect is significant as it allows vehicles to exit easily without requiring complex maneuvers. This addresses safety concerns, as it also discourages through traffic and enhances neighborhood cohesion by reducing cut-through driving. The design can also contribute to more usable space, as this area often features landscaping or recreational spaces.

The other definitions do not capture the essential characteristics found in the typical col-de-sac design. For instance, a side road with no exits could imply a lack of return or access options rather than the intentional design of a turnaround. Similarly, a street that loops around suggests a different configuration that provides continuous circulation, while a narrow passage between buildings denotes an entirely different urban feature unrelated to the characteristics of a col-de-sac.
