Lanes are designated sections of a roadway or path that guide vehicles or pedestrians in a specific direction. They help organize traffic flow, ensuring that vehicles stay in their designated areas, which enhances safety and efficiency. Lanes can vary in width and purpose, including bike lanes, bus lanes, and turn lanes. In addition to roadways, lanes can also refer to sections in swimming pools or sports fields. For example, in a swimming pool, each lane is marked to keep swimmers separated, allowing for fair competition. Similarly, in sports like track and field, lanes help athletes maintain their positions during races.
