I can't seem to find any evidence of this question, but I'm surprised by that, so pardon if this has been asked.
If one is mapping crime location reports, by XY coordinates to streets, to create "hot street" segments, how does ArcGIS handle intersections? Which street (the East/west or north/south) and/or which side of the street, gets counts of events at intersections?
Is there a default logic to this? Looking at my map some segments get both intersections, some get one, and they all go to east/west streets, not the perpendicular intersecting streets.
For the left/right (east/west) issue, where some segments get both intersections and some get one, my guess was it's based on a true north/south/east/west grid, and whether the intersection is to the east or west, but I can't figure out why the perpendicular streets don't seem to get intersection incidents.
Maybe a work around is having those counts be specific to the intersection and not to the line segment? But, I'm not sure how to do that.
Thanks for any help in understanding how the system apportions these counts.
