New subject: ABJ30 Members and Friends/a possible suggestion of experiences with integrarted mapping data document and communciations support tools(in Response to Vladimir)

19 Jun 2008

ABJ30 Committee Members and Friends,

We now have the final Data & Information Systems Section Retreat Report
(attached) and it is time to move forward with our combined support for
the Section Initiatives - and to get our own Committee priorities (also
attached) transformed into real Research Statements with funding
possibilities.  The Annual Meeting is taking shape (see attached "Plans
in the Works" )- so far - we are supporting an ADUS Applications
Workshop, co-sponsoring the NHTS Workshop and a workshop on practical
ways to improve transportation-related data.  We still need to get the
Census Sub Committee and the Joint ADUS Committee scheduled.  National
Data is heading up the Travel Data Users Forum - more details soon.
Hopefully, some of the ideas below from Members and Friends will be
addressed in the "Practical Ways" Workshop - but I would encourage
everyone to provide feedback on moving these areas of interest so they
can reach the Research Statement stage - and we can start looking for
sponsors and funding! 

Hope to see everyone at NATMEC!!!!!

Kate

I. Information systems

- GIS as an integration base: development of GIS-T and transportation
multi-year master networks. We are trying to integrate supply data with
TIP/RTP/LCP information; LRS-based systems - might be good for 1/2 day
workshop. The system integrates data flow across MPO business processes
from collection to modeling to Regional Plan.

- Data integration: One direction: supply data counts - travel time -
safety data (we are doing a project on this right now) Another direction
- integration along business processes in metropolitan planning (data
collection / acquisition - data management - data control and analysis -
forecasting/modeling - planning)

- Data accessibility/analysis - we still have a long way to go here.
Looks like private sector is leading now. Might be a good topic for a
workshop or a session. I mean web-based technologies and analytical
tools that will facilitate data utilization. Its related to the previous
two.

II. Possible items for cooperation with ABJ40 - where emerging
problems/issues with travel surveys can be addressed with new
technology:

- household surveys: changes  in people's behavior and communication
technology resulted in ever dropping response rates and necessity to
look for different methods of data collection (cell phones surveys, GPS,
progress, issues) - They have some calls for papers on this, but it
seems like some important issues are still not getting enough attention,
how survey methodology affects applicability of the results, etc. 

- household surveys: move to bigger samples - should we go back to this
direction? (that is still the approach in Canada, for example)

- Intercept surveys are under fire in some places (there is an excellent
TTI report on this) and we encourage advancements in automated data
collection (cameras, etc.) again, issues: cooperation with DOT on
license plate information, road closure permits for installations,
quality of the data, etc.

- Travel time and speed data: move from floating car technology to an
ongoing data collection by third parties  - implications

- Transit surveys - struggle with low completion rates 

- Truck travel surveys - low response rates, how new technology can help
us, how we can establish channels of cooperation with private sector,
place for the new collection techniques

- Luck of independent data sets for travel forecasting model validation
(survey data normally used 100% for estimation/calibration), supply data
can be used only for certain final validations

- Data requirements of the Activity-Based Models, how the movement
towards disaggregation and microsimulation in modeling affects data
collection 

Ideas from Committee Friends

Ken Dueker (duekerk(a)aol.com)

One data area that Dick Lycan and I have been concerned with is working
(mandates or incentive) with Assessor's to gather accurate counts of
number of units housing units on parcels of land.  An accurate count of
HUs is important to many demographic based transportation demand models.
Yet it is not counted with care by assessors and they have not incentive
or mandate to do so.
