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 3.02, 3.53, 3.54 and 3.54. Overall, the SNDi of the aggregate street network has risen: the street network in Al Qatan has become more disconnected. This increase has slowed: between 1975 and 1976-1990, SNDi rose by 0.5 points, but between 1991-2005 and 2006-2020, it rose by just 0.0.
