The chart above shows, for each construction period in Parvathipuram, the SNDi of new street additions (bar height) and the volume added (bar width), so that bar area reflects the total disconnectedness burden of that period's construction. The 2006-2020 period contributed the greatest disconnectedness burden, with 6 km of street added at an SNDi of 13.91. Overall, the SNDi of new street additions followed a zig-zag trend with an overall increase.

Effect on the aggregate network
New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 0.59, 1.64, 2.14 and 2.45. Overall, the SNDi of the aggregate street network has risen: the street network in Parvathipuram has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 1.04 points, but between 1991-2005 and 2006-2020, it rose by just 0.31.
