Greater Columbus Job Densities

As promised in my post about Columbus densities, I have broken down data provided by MORPC to provide a map based on job densities in Columbus (Source: MORPC TAZ Shapefile). I apologize for not having as much information as usual but I'm still going through it. I will say that I would prefer if MORPC utilized latitude / longitude coordinates rather than NAD 83 Ohio South configurations, but that sounds a bit wonky, right?

As with all gradient maps, I had some choices to make. The numbers ranged between 0.01 to 2.5. This means that the lower job density areas would be washed out if I set a large gradient or the higher job density areas would blend with lesser densities if I set a small gradient. I erred in the latter direction just because it does a better job illustrating the map.

Finally, what are the units? I have no idea. The area values ranged from 2,000 to 100,000. I used  total jobs divided by the area. If anyone has any suggestions, I'm open ears.

Without further ado:


  1. So the highest residential density is between OSU and downtown and the highest employment density is between OSU and downtown. Seems obvious that the best place for a higher capacity transit line is between OSU and downtown.

    You could also make a case for better service out to the job centers along 270 and perhaps between the centers on 270. Ideally, places like Tuttle Crossing, Crosswoods, Westerville, and Easton could all be transformed into high density, mixed use, walkable town centers centered on a transit hub. That's easier said than done though.

    1. I think those are some good ideas. COTA should focus on the speed aspect of transit to show that transit doesn't equate to being super slow. I've always liked your idea of adding BRT-Express buses by utilizing the freeways.
