Una tool Overview (5) -- betweenness index example

1. Start ArcMap.

2. Open the data of Cambridge and Somerville.

Building_polygons is the bottom layer data of a building, cam_som_streets3 is the road network data, cam_som_junction2 is the road connection point data, building26513_weights is the building point data, contains the volume data that can be used as the weight.

3. The parameter settings are as follows:

Enter the building selection data, the impedance is the length, and the search radius is 300 feet. Only the betweenness parameter is calculated.

4. The calculation result is:

Q: Why do we think the betweenness index is a little big in comparison to the calculation formula?
