22. The Operations Engine * * Users can employ their own traffic simulation models to estimate diversion as explained in Phase IV. In such a case, diversion estimates would be entered into the Planning Module manually.

23. More Refined Diversion Analysis Microsimulation provides a more refined estimate of traffic diversion based upon: Microsimulation provides a more refined estimate of traffic diversion based upon: – Additional Project Information – What-if Scenarios – Interactions With Nearby Links
