2. Today’s Agenda GTA Model V2 Migration Update Software improvements
Demonstration
Early feedback
Software improvements
Improved updating procedure for XTMF
Progress reporting in Modeller Tools
Emme Resources
New Tools
New Worksheets
CCGEN feedback
Discussion of Model Output

3. GTA Model V2 Migration Emme databank upgraded to Emme 4 & NCS11.
XTMF ↔ Emme integration completed & tested.
Model framework completed & running.
Generation stage validated.
Currently validating distribution.
[Demonstration]

4. Software Improvements
XTMF:
New XTMF Update procedure which works with highly-restrictive firewalls.
New look-and-feel for parameter editing.
Module documentation accepts simple HTML.
TMG Toolbox:
Progress-reporting to the Modeller window implemented for some tools (e.g. CCGEN). This also works for reporting progress to XTMF.

5. Emme Resources: New Worksheets
As part of on-going work on travel data visualization, several new Emme worksheets have been developed:
VDF worksheet
Transit Line worksheet
V/C ratio worksheet
Desire lines matrix worksheet
Zone polygon choropleth worksheet
Various histograms (link, nodes, matrix)
[Demonstration]

6. Emme Resources New non-legacy transit assignment Tools:
Basic Transit Assignment
Station-to-station Transit Assignment
Feedback / Suggestions?
CCGEN?
Other new tools?

7. Discussion of Model Output
Looking to discuss future model features.
What data is important for model calibration? What data gives you confidence in a model’s accuracy?
e.g. PoR-PoW links, demand matrix control totals, mode splits, link volumes at count stations, boardings on transit links, etc…
What data is desired as output from the model? What data is the primary output data you are interested in?
e.g. VKT, link V/C ratios, transit segment V/C ratios, travel times, transit line profiles, link volumes, emissions, etc…
