SCANNER+: Neighborhood-based self-enrichment approach for traffic speed prediction
Traffic speed prediction is crucial for urban mobility and safety. However, current methods struggle with complex spatio-temporal interactions and limited external contextual data. SCANNER+ introduces a novel neighborhood-based self-enrichment approach to explicitly model these interactions, leveraging spatio-temporal correlations to enhance prediction accuracy without relying on external data sources. It demonstrates superior performance, improving prediction across various model architectures.
Executive Impact & Key Findings
SCANNER+ delivers significant improvements in traffic speed prediction by innovatively using spatio-temporal correlations for self-enrichment, offering a robust solution where external data is scarce.

Core Problem Solved by Self-Enrichment
Limited External DataTraditional prediction models often rely on external contextual information (e.g., weather, events) which is frequently unavailable or scarce. SCANNER+ overcomes this by self-enriching data using internal spatio-temporal correlations within the road network.
| Method | Key Feature | Avg. RMSE Improvement |
|---|---|---|
| STNorm (Baseline) | No enrichment | 0% (reference) |
| OS-SCANNER+ | Only Spatial Correlation | Improved over STNorm |
| OT-SCANNER+ | Only Temporal Correlation | Improved over STNorm |
| SCANNER+ | Full Spatio-Temporal Correlation | Best Performance (4.10% Avg.) |
Generalizability Across Models
SCANNER+'s self-enrichment mechanism is model-agnostic, demonstrating its ability to enhance various state-of-the-art traffic prediction models. By providing enriched data, SCANNER+ helps models like GRU, STGAT, WaveNet, and STNorm achieve better performance, making it a versatile pre-processing layer for existing infrastructures.
- GRU MAE improvement up to 6.69%
- STGAT MAE improvement up to 8.23%
- STNorm RMSE improvement up to 8.51%
