Measuring Betweenness (passing count)

This post show tips with Akasaka(Tokyo Japan) street model.
.graph file or .3dm file importing.

Specify Origins: Origin/Destination panel → +-Origin → mouse click

Specify Destination: Origin/Destination panel  → +-Destination → mouse click

Measure passing count: Compute panel  → Betweenness(Passing Count)

Set ranking annotation (1st best only ) Display panel  → check Show Rank, set the number 1

It says most high passing nodes have 2 count.

What if we change the weight of the Origin node?
(for example, assuming there are multiple people at the Origin node)?

Set weight at Origin nodes: Origin/Destination panel → Set Weight → Dialog will appear at each origin node.

In this sample, Origins are named A, B, C and D. We set the weight of Origin A as 5.0.

Measure passing count: Compute panel  → Betweenness(Passing Count)

It says most high passing nodes have 6 count.

What if we route by shortest paths and 2nd shortest paths?

Set the condition of routing: Shortest Paths panel → set k = 2

What if routing from All nodes to All nodes by shortest paths?

Origin/Destination panel → Clear ALL

Set the condition of routing: Shortest Paths panel → set k = 1

Set all nodes as Origin: Origin/Destination panel → All Nodes

Copy Origins to Destinations: Origin/Destination panel → Copy:->Destinations

Measure passing count: Compute panel  → Betweenness(Passing Count)

Set ranking annotation (1st ~ 3rd ) Display panel  → check Show Rank, set the number 3

媒介度ランク Ranking of passing count
  • best: 21,136 count
  • 2nd: 19,724 count
  • 3rd: 19,628 count
