Overview

Comparative evaluation reveals regional driving behavioral differences across Chinese and German highway datasets, suggesting targeted scenario generation accelerates automated vehicle validation.

Key Points

To quantify cross-regional driving behavioral differences and automate the generation of region-specific test scenarios, preventing redundant automated driving system validation.
Formulated a 14-dimension highway driving behavioral taxonomy to compare naturalistic driving datasets from China and Germany across matched traffic states.
Introduced a dual-track assessment coupling deterministic formulas with a Large Language Model (LLM) agent to evaluate context-sensitive dimensions, including lane-change aggressiveness and interaction danger.
Quantified divergences using Cliff's delta and applied a regional differential filter to generate batch-executable OpenSCENARIO test fragments for Hardware-in-the-Loop (HiL) validation.
Identified statistically significant and practically meaningful cross-regional behavioral differences across multiple dimensions and traffic states using Cliff's delta.
Demonstrated that the dual-track LLM-assisted framework successfully pinpointed areas of divergence between deterministic and agent-based evaluations for complex, context-dependent driving behaviors.
Produced an automated library of OpenSCENARIO fragments that isolates regional differences, reducing retesting burdens when transferring systems across jurisdictions.
