Crosses, or intersections, are points where two or more roads meet. They can vary in complexity, from simple two-way stops to multi-lane roundabouts. Traffic control devices, such as stop signs and traffic lights, help manage the flow of vehicles and pedestrians at these locations, ensuring safety and efficiency. Intersections are crucial for urban planning and transportation systems. They facilitate movement between different areas, allowing for access to various destinations. Proper design and signage at intersections can reduce accidents and improve traffic flow, making them essential components of road networks in cities and towns.
