The TSD (time-step data file) is created by CORSIM and contains the positions and speeds of all vehicles in the CORSIM network. CORSIM creates a TSD file as it runs. When finished, programs like TRAFVU can read the TSD file, permitting visual review of the inner workings of the simulation.
---- Dr. John Leonard , Virginia Commonwealth University
This repo contains a renewed python script to interpret the TSD file generated by CORSIM. It provides students hands-on experience on what information the time-step data file contains, how it is structured and encrypted. The student interested in the underlying simulation coding could use the parsed time-step CSV file to create the time-step frames and play an animation.
The general decryption idea is mentored by Dr. John Leonard. His source code inspires the output format in source-forge.
The source of the file is located in TRAFVU V1.4, with the repository structure shown as below:
├── doc
│ ├── FileDescription.pdf
│ └── config
│ ├── message_content.csv
│ └── message_content.xls
├── input // folder contains some sample inputs
│ ├── 4leg.ts0
│ ├── CapOkland.tid
│ └── CapOkland.ts0
├── output // output csv file would be drieted here
│ ├── CapOkland.csv
└── parser_csv.py
The developer or user needs to run the parser_csv.py by setting the proper input file name and other parameters.
