Analysing the spatial pattern of road networks in Kimberley, South Africa

The increasing burden on South African road networks necessitates sustainable solutions that conclude their spatial configuration and arrangement. A deeper understanding of the existing network’s organisation is, therefore, required. This study evaluates structural design in Kimberley, Africa, using network science open-source OpenStreetMap data. Nonplanar-directed multigraphs for Kimberley are constructed to analyse morphological characteristics network. area was evaluated with several network-analysis methods such as completeness, degree centrality, betweenness, closeness, PageRank. found has a low centrality 0.00111. indicates should be less congested because there fewer vulnerable spots. Because availability two-way streets, total edge length is nearly double street length. There 2.97 streets radiating from nodes average. suggests three-way intersections prevalent Kimberley.
