Mark- Since you are using 2006-2010 tract data, could you do a visualization by mode, at least at a high level like the 2009-2013 ACS? That would involve
summing the data to 4 modes: auto drive alone, auto carpool (all other auto occupancies), public transit (sum all transit modes) and “Other” which includes everything else, but is mostly walk, bike, taxi and motorcycle. I realize there are less valid
data points, but you could see how different transit was compared to drive alone. Tom Marchwinski, MTA- Metro North Planning

I added a couple of new things. Now, when you move the distance criteria down to 0, it will include commuters that commute within the tract. The dot won't move (obviously), but it will show and the numbers will be included in the totals.
Thus, if you select "ALL" for distance and "ALL" for CV you will get the full info for the county. Performance may (by which I mean definitely WILL) suffer, but the numbers will be there and the animation might be acceptable.
Also, it is not really visible at all, but if you place the cursor over the map and click (not on a dot) and hold the mouse button for a full second, the map will enter a "drag" mode that will let you click again and move it around. It
is still a bit clunky (and the dots disappear, making a bit harder to see where you wanted to move it.) When you finish dragging the map, or if you move the cursor outside the map, the dots will reappear.
Hope this helps. I might add a few more things. Any suggestions are welcome. Cheers.
Mark

I have made some suggestions to Mark for how to make his commute flow tool show how all the commuters
can be accounted for. He has already made some changes and plans to make some more. He has included an “ALL” button so that all lengths of commutes can be shown if choose and not just up to 300 miles, and an “ALL” button for the CV (and not just <100%). He
said he would add the source of the data to the text and he may map the intratract commutes as well since it is helpful to visualize all the within county commutes. Do you know when the next set of tract to tract flow data will be available as he is willing
to update when available.
Thank you,
Ginger

Turns out internal (intra-tract) flows are not reported. This should account for nearly all the
missing workers.

They may only be mapping those flows that have enough records so there is not an imputed or suppressed
O-D pair, which would mean sometimes up to 50% of the records do not have flows, so its missing half of the flows. Those show up as 0 workers due to suppression. Tom Marchwinski

I would be cautious, just did a quick check, it says ACS, but unsourced as to what ACS (I’m guessing
2009 – 2013 county to county flows – otherwise OD pairs are very tricky), also looking at just Montgomery county and DC, and expanding the tool to its maximum range (zero to 293 miles) it’s missing about half the total workers in each of those. Also, tracts
are referenced, but that set is not reported at tract. I welcome your thoughts.

Check out this CTPP animation map – we didn’t make it. It’s very cool, wish we had-
