It is always difficult to figure out boundaries between different TRB
committees, so don't forget that there is the Travel Survey Methods
committee (ABJ40) that Guy Rousseau is now chairing (and I used to chair
it a long time ago). Kouros Mohammadian and I co-chair a New
Technology subcommittee and the subcommittee has long discussed GPS, and
in fact, I said at the last subcommittee that GPS is not really "new
technology" anymore and maybe we should stop discussing it! But, the
integration of GPS into smart phones (3G and 4G) is new, so we'll keep
it on our list.
We also have a Call for Papers out on Cybermining of Social Media to
capture travel and activity behavior.

I believe that we will be editing this into a full NCHRP proposal
statement.

Agenda(ABJ30:TRB Urban Data Committee)
Good questions, Emily. A few points for whatever they worth:
In our case the first one is kind of rhetorical - we definitely will and
are using already new data sources, including commercial travel speed
data, GPS household surveys, etc. Some of them are also much more
efficient ways, so you can get better/larger sample data at a lower
price or a comparable price.
We might want to consider a subcommittee on innovations in urban data
collection and data management, including data acquisition, data
retrieval systems, web-based data portals, etc.
It seems to me that travel time and speed data bear the most relevance
for the urban environments, so I would agree with you that it probably
does belong to this committee. But what and how we collect is changing.
I also would suggest another topic related to changing ways of using
data and changing applications. We can call it "New requirements for
urban data collection and management" or something like that.
Specifically we have new emerged needs on the modeling side, that
relates to necessity to collect more accurate GPS-based data for
activity-based models and another big powerful trend - requirements for
data for dynamic traffic assignments on regional or sub-regional scale
and microsimulations on both supply and demand sides. We just completed
region-wide intersection data collection for TMC and approach counts
with simultaneous aerial photography for queue length and density and it
was a somewhat difficult exercise - so different ways of doing it might
be interesting. As more and more planning agencies move into simulating
dynamic phenomena on a disaggregate level new requirements for data
become more and more pressing.

Subject: [ABJ30-Friends] Discussion Items for the Mid-Year Agenda
(ABJ30:TRB Urban Data Committee)
Hi!
Kate Lawson and I were emailing about the agenda for the Mid-Year
Meeting at NATMEC in June in Seattle and I was thinking that it may make
sense to have discussions among the participants (in-person and on the
phone). I came up with the following discussion topics. Please feel
free to edit these (responding to the listserve or me:
emily.parkany(a)gmail.com ) and add your own suggestions.
1) Do we need new sources of data? Have people been following the
status quo or is the practice moving towards using archived ITS data for
planning, GPS surveys, location-based data, etc.
2) Do we have the right skills? What skills do we need new hires to
have? Can a TRB workshop or other training address this?
3) Do we have the right subcommittees? What is the impact of census
data and archived data among the participants? Should the commitee be
considering other subcommittees (for example: travel time, speed, and
reliability---and the SHRP 2 Reliability efforts)?
4) Is the urban data committee the right "home" for Travel Time, Speed,
and Reliability? [I lean towards yes.] Is there much coordination
between these researchers (for example, folks on SHRP 2 Reliability
projects) and the committee?
Do these topics interest you? Kate suggests that they fit under a
"Preparing for the Annual Meeting/State of the Committee" Discussion
theme. The mid-year meeting is not very long but this may be our chance
to raise some of these issues.
When we put an agenda together, I will ask you to think about these
topics and I'll solicit opinions that we can put into a Powerpoint
presentation to start the discussion. This way, I hope that people can
participate before the meeting, in the room, and on the phone.
I look forward to hearing from you.
