Traffic Assignment (TA) Tutorial

The only MSA + FW + PBA code implementation you can find in Python. The implementation is based on the book Transportation Network Analysis by Stephen D. Boyles, Nicholas E. Lownes, and Avinash Unnikrishnan.

Please note that the code is for educational purposes only. The code is not optimized for large-scale networks.

If you find the code helpful, please consider giving it a star.
