I have a list of addresses of people participating in carpools to a workplace and a list of cars given by the workplace. Both lists change daily.
I need to group people by their addresses and assign them cars by the group size (and then calculate their route to work, but that's the easy part).
How can I group points (worker addresses) by their geographic location, or better yet, by their closeness on the road network?
I'm using ArcInfo 10.1. I tried using the Grouping Analysis (which groups by geographic location and distance from the workplace), but it's giving me weird results.
