In developing countries, demand aspects of public transit have received very limited attention as compared to the design and engineering aspects. Further, transport studies conducted in those countries are suffering from virtual lack of a database on urban transport statistics or project based or either very aggregate.
Given circumstances, there is a need on a simplified method to measure transit demand of public transit stops. This study suggested that network centrality measures tool is robust, dynamic planning tool that will offer promise for transport planning applications in Indian context.

Centrality demand is good for rough estimates however from real transport planning view even small section which are neglected in database need to be taken care off because transport is essential support system for each human being. either it is disabled, elderly or child or women. Safety, security and transportation is essential ingredient for each human being . which i m afraid get diluted in Centrality theory
If I understand correctly, you want to be able to make and use some quick estimates of "centrality" (say from a map, or by counting the number of arcs incident on a node?). This can be taken one step further by building a connectivity matrix (X_ij = 1 if nodes i and j are linked; 0 otherwise). Many aspects of the network, including identification of important (central?) nodes can be found from manipulating the POWERS of this connection matrix. (See Taaffe, O'Kelly, Gauthier, Geography of Transportation.) However, to get a good idea of actual traffic / flow through these nodes, need an interaction matrix (W_ij) and an idea about how the traffic is assigned to the paths. I do think it is a good idea to develop sketch plans and centrality methods can be useful in the absence of better data. (Ideally you need to have real sample travel demand as well as the supply side.)
I think Centrality measures can serve in one stage of the Transportation modeling process: identifying and pinpointing populations.... but in order to complete your modeling you need more data about the transportation networks, vehicles, distances, accessibility and smoothness of flows in order to have a real simulation of the transportation network.
Our research studies indicates that network centrality has capabilities to model traffic flow patterns. It has capabilities to explain human movements in terms of matrix distance as well as cognitive behavior
