TRAFFIX™ can analyze a single intersection without the inclusion of zones, gates, or links. TRAFFIX™ can also be used to model a large regional roadway system with hundreds of intersections. Because TRAFFIX™ is primarily a node based analysis tool the operating limitations of TRAFFIX™ are related to the number of nodes.
| Absolute Limit | Observed File Maximums / Notes | |
| Intersections | 65,000 nodes | 250 intersections modeled |
| Zones | 65,000 nodes | 25 zones |
| Gates | 65,000 nodes | 30 gates |
| X,Y coordinate | -10000, -10000 to +10000, +10000 | Coordinates are integers. |
