Hi! I'm trying to find corners of a city with a high concentration of traffic crashes.

First of all, I´ve tried with kernel density analysis, but I'm wondering if there is something that makes a sort of a ranking of corners, so I can determine which is the most dangerous corner of our city. Sorry if this question is silly, but I'm new with spatial data and I'm eager to learn new things on ArcGIS.

thank you!!!

Create or ensure you have a dataset of corner features (points/short lines etc).

Run a Spatial Join with a Count merge rule to find the number of incidents within a specified radius from the corner.

By 'corners', you must mean street intersections, correct?  How is your incident data presented to you?  Is it a table or an actual feature class?

That should just about do it....
