There are three types of habitations in the Block Map – those which are connected, having all-weather roads, (ii) those which are not connected at all, (iii) those which are connected only by a fair-weather road. In the case of connected Habitations, it is possible that there are more than one road connections. In such a case, one road should be selected using Socio- Economic infrastructural parameter criteria. If, for any reason, an alternative road is the preferred choice of the local people, that road may be chosen, but, in any case, only one road should be selected for the Core Network, as the intention is to provide Basic access. In case of unconnected habitations, a suitable road connection should be identified, which would generally follow the alignment of an existing track. Quite often an unconnected habitation can be connected in more than one way. Often the market centre is in a different direction from say, the taluka headquarters. In case a consensus is not easily reached the choice from various alternative links may need to be made on the basis of weightages accorded to different socio-economic services. Since PMGSY envisages only single connectivity, it is necessary to choose the most efficient road link in terms of utility.
The Core Network Plan shall thus be prepared for the entire Block. It should be checked again that all the Habitations are connected or will be connected to the nearby Market Centres, either directly or indirectly through other all-weather roads. It is not necessary that each Habitation is directly connected to the Market centre in a hub-and-spoke configuration.
Going by the definition of an all-weather road as given in Chapter-1 Operation Manual, it is not necessary to provide a road to a Habitation that is within 500 metres of an already connected habitation or an all-weather road. All such habitations should be treated as falling on the concerned road.
Suggestions/ proposals received from elected representatives including MLAs and MPs, Panchayats, and local population must be properly examined as these can provide very useful information about the missing bridges, missing links and other priority demands of the local community. The existing road Network, location of major Market Centres, topographical features, and local travel pattern should be kept in mind. While deciding the Core Network, the fact that it will be used primarily by the local people must be uppermost in the mind.
