Data and code for C-S-E structured functional anomaly diagnosis in autonomous car-following

This Zenodo record contains the derived data tables, result tables, analysis scripts, configuration files, selected CARLA simulation source files, and final figures supporting the manuscript "Functional Anomaly Diagnosis and Rear-End Conflict Risk Analysis in Autonomous Two-Vehicle Car-Following: A C-S-E Structured Feature Fusion Approach". The archive includes CARLA-derived run-level, early-window, and paired feature tables; closed-set, weather-preset holdout, early-detection, ablation, pair-clustered surrogate-safety, OpenACC feature-level, and trajectory-conditioned perturbation result tables; Python scripts for feature preparation, model evaluation, result summarization, and figure generation; and the final manuscript figures. Raw per-run CARLA time-series logs and raw simulator output folders are not included because of storage size. The manuscript analyses are based on the derived feature and result tables included here, and the raw logs can be regenerated from the provided source files and configuration files in a compatible CARLA environment.
