Cul de bus, also known as a bus loop or turnaround, is a designated area at the end of a bus route where the bus can turn around and head back in the opposite direction. This circular space allows for efficient and safe maneuvering of the bus, ensuring a smooth and timely journey for passengers. Cul de bus can also refer to the physical structure or layout of the area, which may include bus shelters, benches, and signage for bus schedules. In some cases, cul de bus may also serve as a transfer point for passengers to switch to another bus or mode of transportation. Overall, cul de bus plays a crucial role in the functionality and convenience of public transportation systems.
