Replication Code for Crash Risk Prediction Guided by Large Language Models Using Pre-Crash Trajectories  

This code-only replication package accompanies the revised manuscript “Crash Risk Prediction Guided by Large Language Models Using Pre-Crash Trajectories” submitted to Communications in Transportation Research (Manuscript ID: COMMTR-2026-0063.R1). The package contains the implementation of the lightweight temporal graph student, offline LLM-guided knowledge distillation and fine-tuning workflows, evaluation and deployment benchmarking scripts, configuration files, environment specifications, a documented data interface, and a synthetic end-to-end smoke test. It also includes a Replication Explanatory File and a SHA-256 integrity manifest.
