Graph-Conditioned Mixture of Graph Neural Network Experts for Traffic Forecasting

Researchers propose GC-MoE, a graph-conditioned mixture of experts framework that improves traffic forecasting by assigning specialized neural network experts to different road segments based on graph topology. The approach trains only 17K parameters while leveraging 1.5M frozen expert weights, achieving competitive results across four standard traffic prediction benchmarks.

From XXLTraffic to EvoXXLTraffic: Scaling Traffic Forecasting to Sensor-Evolving Networks

Researchers introduce XXLTraffic and EvoXXLTraffic, new datasets spanning 27 years of California and Australian traffic sensor data that account for real-world network growth. Unlike existing benchmarks assuming fixed sensor networks, these datasets expose the challenge of forecasting across dynamically evolving road infrastructure with sensor growth rates exceeding 10,000%, and reveal that current state-of-the-art models fail to generalize under such conditions.
