The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Results show that LISA reduces mean control delay by up to 89.1% and maintains Level of Service C while all non-LLM baselines degrade to Level of Service F. Under near-saturated demand, LISA reduces mean waiting time by 93% and peak queue length by 60.6% relative to fixed-cycle control. It also lowers fuel consumption by up to 48.8% and achieves 86.2% intent satisfaction.

C2weakest assumption

LLM inference can be executed with low enough latency to support real-time sub-second speed advisory decisions despite the acknowledged limits of current LLM inference speeds for sub-second control.

C3one line summary

LISA applies LLMs as primary decision-makers for signal-free intersection management, cutting mean control delay by up to 89.1% and maintaining better service levels than fixed-cycle, SCATS, AIM, or GLOSA baselines.
