Since I have gotten some individual messages, I am going to post a response to the entire
This was a PROTOTYPE only, and I think it is useful to review this website if you are
working on developing a similar system.
I don't think that these are the best "metrics" (aggregate trips, aggregate
VMT) because I prefer PER PERSON and PER HOUSEHOLD measures. But, I am sure that other
people prefer aggregates for their State, rather than per capita or per household. If you
are in "dashboard", if you click on a state in the thematic map, it gives annual
person trips (and of course, I would prefer Weekday Daily, and Weekend Daily).
One of the things I really liked was the "pie-bubbles" because you can see (if
you pay attention), for example, that while "personal/family business" trips are
MORE vehicle trips than "work" trips, that the VMT for "work trips"
exceed VMT for "personal/family business" for the States that I selected. The
pies are presented in sorted order (high to low) with the size of the bubble (circle)
relative to each other. (Note to ORNL-maybe the trip purpose labels should be different
colors, so that people recognize that the bubbles are in different sort order when they
click on trips, or vmt?)
In the DET table extractors, I like the idea of just by clicking on the drop down
variable elements that you can get the results.
I like the "old" NHTS table generator and find it easy to use, but I think there
are likely some very common elements to make data querying even more simple, so this is a
start along those lines.
This morning, I attended a meeting of NYMTC and NJTPA, and they are currently developing
an interactive tool for looking at their recent household travel survey data (the data
are not yet finalized). I will be excited to find out what GeoStats comes up with.

Subject: [CTPP] Sharing prototype of travel survey data visualization tools developed by
Data Visualization Prototypes from Oak Ridge National Labs,
for Federal Highway Administration
I don't know how long these tools have been available on the NHTS website, but I found
them a couple of weeks ago. I thought I would share the link because these ideas might be
useful for :
1. People who are working on the Commuting in America project
2. People who have their own regional or statewide household survey and plan for
interactive web-based data access tools
