LIDSA: Cognitive Arbitration for Signal-Free Autonomous Intersection Management

arXiv:2605.12321v2 Announce Type: replace Abstract: Large language models (LLMs) show strong potential for Intelligent Transportation Systems (ITS), particularly in tasks requiring situational reasoning and multi-agent coordination. These capabilities make them well suited for cooperative driving, where rule-based approaches struggle in complex and dynamic traffic environments. Intersection management remains especially challenging due to conflicting right-of-way demands, heterogeneous vehicle priorities, and vehicle-specific kinematic constraints that must be resolved in real time. However, e

Why this matters
Why now

LLMs are advancing rapidly, making their application to complex, real-time control problems like traffic management increasingly feasible and attractive over traditional rule-based systems.

Why it’s important

This development indicates a significant step towards fully autonomous, AI-driven infrastructure, which can dramatically improve efficiency and safety in urban environments.

What changes

The reliance on pre-defined rules for autonomous traffic control begins to shift towards adaptive, cognitive arbitration by AI agents, offering more dynamic and optimized solutions.
