Angular Unit: DegreeNetwork Analysis-Number Of Basketball Games That Need Police Supervision in San Francisco, CA

The idea of the Network Analysis is to see whether any SF high schools basketball games between private vs public schools that are out of the 4 mins police response time range. I use the "Closest Facility" Analysis to pick the closest distance within 1000m between private and public schools basketball games, and there are 6 games in total.

The "Service Area" analysis is to see the areas of police can cover in a 4 mins response range. I export the 4 mins police response time in a new layer, and add the 6 basketball games on top of it. It shows that there is 1 game that are out of the 4 mins police response range.

Therefore, that game needs police officers on site to supervise the game if anything injuries or emergency happens.
