Input file placement
For downstream processing, place the existing Basic trajectory CSVs under basic/, using the filenames in ../configs/basic_manifest.csv or pass the actual path explicitly. These files already contain processed vehicle IDs, lanes, directions, positions, velocities and lengths. The README gives the direct risk/pairing/sampling/inference/interaction commands.
For source detection processing, place the raw detection CSVs under raw/ using ../configs/source_manifest.csv. A raw reconstruction lane input belongs under lanes/ and has Frame,Vehicle_ID,Lane number,Direction keyed by original source records. To transfer lane and direction labels from a Basic file, apply the corresponding source/frame/vehicle mapping to the original detection keys.
The processing commands create new files under runs/ relative to the code directory. Each file's generating command and downstream consumer are listed in the README and ../docs/INPUT_OUTPUT.md.
All commands accept explicit paths. For combining sources or joining processed IDs, use the established source/frame/vehicle correspondence and offsets.
