analyze public transportation network characteristics

analyze_ptn(g)

Arguments

g

igraph object, network graph representing the public transportation network, vertices represent stations, which are linked by an edge if there is a direct transfer between them

Value

'data.frame': 1 obs. of 7 variables:

  • vcount number of nodes,

  • ecount number of edges,

  • density network graph density,

  • av_deg average degree,

  • av_cent average unit betweenness,

  • av_spl average shortest path length,

  • diam diameter, and

  • trans transitivity.
