In geography, nodes refer to points of intersection or connection within a network that facilitate the movement of people, goods, and information. Nodes are critical components of the matrix of accessibility, which is a conceptual framework used to analyze the spatial distribution of accessibility within a region.
According to Hansen (1959), the matrix of accessibility is a tool that allows geographers to quantify and analyze the spatial relationships between origins and destinations within a network. The matrix consists of rows and columns representing origins and destinations, respectively, and the cells of the matrix contain measures of accessibility between each pair of locations.
Nodes play a crucial role in the matrix of accessibility by serving as key points of connection within the network. These nodes can take various forms, such as transportation hubs, commercial centers, administrative offices, or communication facilities. Nodes are characterized by high levels of connectivity and act as focal points for the movement of people, goods, and information within the network.
For example, in a transportation network, nodes may include airports, seaports, railway stations, and bus terminals, which serve as key points of intersection for different modes of transportation. These nodes facilitate the movement of passengers and cargo between different origins and destinations, thereby enhancing accessibility within the network.
Overall, nodes are essential components of the matrix of accessibility in geography, as they play a critical role in shaping the spatial distribution of accessibility within a region. By analyzing the connectivity and importance of nodes within a network, geographers can gain valuable insights into the patterns of movement and interaction that characterize a particular area.

Meaning of Nodes in Accessibility Matrix
In geography, an accessibility matrix is a tool used to measure the level of accessibility between different locations. A node is a point in the matrix that represents a specific location. Nodes are typically represented by the coordinates of their latitude and longitude.
Function of Nodes
Nodes serve several functions in an accessibility matrix:
- Identify Locations: Nodes represent specific locations that are being considered in the analysis.
- Connect Locations: Nodes are connected to each other by edges, which represent transportation routes or other means of travel.
- Measure Accessibility: The distance or travel time between nodes can be used to measure the accessibility of each location.
Types of Nodes
There are different types of nodes in an accessibility matrix, including:
- Demand Nodes: Represent locations where people or businesses are located and generate trips.
- Supply Nodes: Represent locations where services or amenities are located and attract trips.
- Intermediate Nodes: Represent locations that are not destinations or origins but serve as points of connection between other nodes.
