InverseVIsTraffic

This is a repository containing all the code for our ongoing Eastern Massachusetts transportation application project.

The Julia code for solving the inverse Variational Inequality problem is based on the repository InverseVIs; an important modification is the calculation of the objective function. In addition, the normalization constraint has also been updated, which, we believe, is more natural in this particular application.

INRIX real data processing

Due to confidentiality of the data, currently the raw INRIX dataset can not be made publicly available. When dealing with this dataset, both Python and Julia have been used.

EMA benchmark network releasing

We have recently released our Eastern Massachusetts highway network as a benchmark dataset; see Github or Kaggle. Interested readers are welcome to download the dataset and cite the following papers.
