Limitations to centrality measures have led to the development of more general measures.

Two examples are

the '''accessibility''', which uses the diversity of random walks to measure how accessible the rest of the network is from a given start node,<ref name="Travencolo2008">{{ cite journal| last1=Travençolo |first1=B.
