Video: How to use the new path assignment plan in Aimsun Next

Technical Note #47

Our Senior Product Specialist, Dimitris Triantafyllos, brings you this new pro tip on how the Path Assignment Plan feature gives you unparalleled flexibility in reusing previously calculated paths.

 

When do I use the path assignment plan?

 

The Path Assignment Plan is designed to serve three purposes:

 

  1. You are running multiple macro assignments, for different periods, and you want to use those paths for different periods within a single simulation;
  2. You are running separate DUEs for different time periods, then you want to run a one-shot that spans multiple time periods without having to run and calibrate a single DUE that exactly matches that period;
  3. You run a DUE for a long period, but then you want to run a one-shot for just a portion of that period without having to run and calibrate a single DUE that exactly matches that period.
