Dear all,

As part of my master thesis, I need to calculate a walkability index of different neighborhoods in Hamburg composed of:

- Land use mix (entropy index)
- Connectivity, represented by the ratio between the number of true intersections (three or more legs) to the land area of the block group in acres.
- FAR (Retail floor area ratio: the retail building floor area footprint divided by retail land floor area footprint)
- Net Residential Density (the ratio of residential units to the land area devoted to residential use per block group.)

I'm having a hard time calculating the Connectivity and the FAR for my neighborhoods. Can someone help me with these two?

I should generate two maps similar to these here:

I'm sorry the legends are in German.

I'm a beginner in ArcGIS. Any help or tutorial would be highly appreciated.

Best,
