Measuring the Nodal connectivity of surface transport network in raiganj block, Uttar Dinajpur district, West Bengal, India

Roads have been described as life blood of Human Civilization. Social interaction and economic prosperity in space have been shaped by the road networks both at intra and inter regional levels. Th e different places at Raiganj Block in Uttar Dinajpur district is connected by the national highway, state highway and district road. The basic essences of this study is to expose the level of connectivity of different nodes in Uttar dinajpur district lying adjacent to these major roads. In this regard graph theoric measurement has been applied to determine the efficiency of transport network connectivity of these nodes. On the basis of the study, it is clear that in terms of cyclomatic number, alpha, beta and gamma index value and ultimately aggregate transport score measurement the nodes has a uniform connectivity which is not so viable for level of development in the region.
