21. Multi-Class Congested Fare-Based Transit Assignment

22. Multi-Class Congested Fare-Based Transit Assignment
Current Work:
Validation
Estimation

23. Centroid Connectors

24. CCGEN tool – TMG Toolbox

25. Centroid Connectors - Issues
Different CCGEN settings produce very different results:

26. Centroid Connectors - Issues
Different CCGEN settings produce different results.
Centroid connectors can significantly impact travel times, especially walk.
This can lead to under-predicting transit use.

27. Centroid Connectors – Solutions
Improved documentation
CCGEN development
Fewer user inputs
Improved algorithm
Estimation of parameters
Workshop
Thoughts?

28. Documentation
Current state and future needs
