Unveiling Stochasticity: Universal Multi-modal Probabilistic Modeling for Traffic Forecasting
arXiv:2604.16084v2 Announce Type: replace-cross Abstract: Traffic forecasting is a challenging spatio-temporal modeling task and a critical component of urban transportation management. Current studies mainly focus on deterministic predictions, with limited considerations on the uncertainty and stochasticity in traffic dynamics. Therefore, this paper proposes an elegant yet universal approach that transforms existing models into probabilistic predictors by replacing only the final output layer with a novel Gaussian Mixture Model (GMM) layer. The modified model requires no changes to the traini
The paper was recently published, demonstrating ongoing advancements in AI modeling for complex real-world challenges, particularly in forecasting dynamic systems.
Improving traffic forecasting with probabilistic models provides more robust and actionable intelligence for urban planning, logistics, and autonomous transportation systems.
Existing deterministic traffic prediction models can now be efficiently adapted to provide probabilistic outputs, offering a richer understanding of uncertainty and risk.

More accurate and uncertainty-aware traffic predictions lead to optimized route planning and congestion management.
Reduced commute times and fuel consumption contribute to economic efficiency and environmental benefits.
The methodology could generalize to other spatio-temporal forecasting problems, accelerating the adoption of probabilistic AI across various industrial sectors.
