This page documents some of the NCSA AVL Group's work toward developing visualization systems for the TRANSIMS regional transportation modeling and simulation software environment.
This is ongoing work in conjunction with TRANSIMS developers at the Argonne National Laboratory TRACC Center.
Maya Plugin 3-D Visualization Animations |
|
|
Alexandria: Visualization of microsimulator data generated from the TRANSIMS Alexandria example simulation. Maya and NCSA's data visualization plugin were used to produce the image. Vehicle paths from the microsimulator were converted to a trajectory representation and then read into Maya. |
|
Chicago: Microsimulator data from the Chicago simulation, provided by researchers at Argonne. Considerably more vehicles are simulated for Chicago than for Alexandria. Microsimulator output was converted to a particle representation, instead of a trajectory representation, for efficiency. |
Interactive Data Access Software |
|
 |
Prototype of interactive visualization of TRANSIMS microsimulator output. The road network is displayed, and the vehicle positions are shown on selected (orange) links. The data are from the 1-second snapshot output from the Alexandria example. |
ArcGIS Explorer Implementation |
|
|
The image is an example of plotting vehicle id 5000 from Alexandria micro simulator data within ArcGIS Explorer. The yellow pins mark the vehicle position and the red pin represents the user's note about a particular position. |
| This is a prototype showing 800,000 buildings within the Chicago Transims simulation area using ArcGIS Explorer. |

Mapping Frustration:
Large dots mark "stuck" cars, which have not moved in one or several minutes, from the Alexandria simulation at 8:32am. |
