Story summary

Tohoku University researchers in Japan developed Harvested Reservoir Computing (HRC) that uses real-world traffic as a computing resource to reduce energy consumption.
The method uses urban road dynamics and vehicle interactions to forecast with minimal computation and energy use.
Predictive accuracy peaks just before traffic congestion, and this enables efficient forecasting without specialized hardware.
