What is the degree of direct linkage between one particular location and other locations in a transport network referred to?

The degree of direct linkage between one particular location and other locations in a transport network is referred to as "connectivity." Connectivity measures how well a location is connected to others through various transport routes, which can include roads, railways, or air routes. High connectivity indicates that a location has numerous direct transport links, facilitating easier access and movement, while low connectivity suggests limited direct routes, potentially hindering transportation efficiency.
