Design Issues

The current plan is to faithfully re-implement the MTC TM1 model design. However, there are issues with the design that we want to eventually address. The purpose of this page is to keep track of these issues, questions, etc.

Issues

  • arbitrary identification of the person attributes to use for joint tour models
  • trip mode choice logsums may be a bit overkill in some cases
  • improve availability constraints (shopping trips with a destination choice sample with no retail employment for example)
  • maybe the system shouldn't fail, but fallback to something simpler and log it (like when assigning trip travel time within the available time windows)
  • how best to integrate multiple zone systems
  • Learn from DaySim, which sometimes re-simulates when it gets stuck
