A node is the meeting point of two or more routes, a point of origin, a point of destination or any sizeable town along a route.
Nodes play a crucial role in establishing connectivity within a network.
They are key points for the exchange of information, goods, or services. In transportation networks, nodes often represent transportation hubs like airports, train stations, bus terminals, or major road intersections.
As networks expand and grow, new nodes may be added to accommodate increased connectivity or to improve efficiency. Identifying suitable locations for nodes is a critical aspect of network planning.
