to TRANUS
Hello everyone!
I am a graduate student currently conducting research on the TRANUS model for the Hangzhou project. The rough model has been built and I would like to inquire about some adjustments to the details. Here are some of the main issues:
1. How to segment a mode of transportation to study tail number restriction policies, such as dividing one of the originally defined operators - cars - into car 1, car 2 Cars 5, divide them into 5, representing five types of car tail numbers. Meanwhile, maintaining the sum of their travel volumes equal to the original cars.
2.When running the Run Location module for future year scenarios (sorry, I am using an old version of TRAUNS instead of the latest qTRANUS), the model reports an error of "ERROR # 10013: Numerical error in logit. Generalized cost less than zero." Due to the large number of modules in the model, I am confused about which part to modify.
3.When running the Assignment program of the Run module, the "ConvFlows" of each iteration result in the result window remains at 1, which does not converge towards the convergence target. Should I modify the road segment in the Worst column?
If anyone has corresponding suggestions and improvement measures, please feel free to contact me. Thank you very much to everyone who has read and responded!
