A junction is a point where two or more roads, paths, or lines meet or cross. It is commonly used in transportation to facilitate the movement of vehicles and pedestrians. Junctions can vary in complexity, from simple intersections to more elaborate interchanges that manage heavy traffic flow. In addition to roads, the term "junction" can also refer to connections in other contexts, such as electrical junctions where wires meet. In telecommunications, a junction may describe a point where different communication lines converge, ensuring efficient data transfer between networks.
