Visualization in the freight domain will increasingly involve the integration of new thinking from the areas of computer science. ‘VISUAL ANALYTICS’ is more of a computer science discipline than the conventional 3D/4D transportation visualization approach to which we have become accustomed.

The eye can, in fact, process more information than can be presented by current high resolution displays

1) Identify key federal and state level ‘stakeholders’

2) Identify data elements and key system variables

3) Identify key ‘decisions’ and ‘desired outcomes’

4) Define the structure of system operation

The BIGGEST CHALLENGE BIGGEST CHALLENGE for the facilitators was in getting participants from different professional backgrounds focused on the intent of the workshop and on rising above their own professional needs to “SEE THE BIG PICTURE” AND “THINK OUTSIDE THE “SEE THE BIG PICTURE” AND “THINK OUTSIDE THE BOX” BOX” when it comes to future needs and priorities of freight modeling and data.
