Ablation Study of a GNN-RL Digital Twin for Urban Traffic Control

5.5 KB of experimental results from an ablation study of a Digital Twin component for urban traffic networks. The dataset, created by Fayez Alanazi and last updated in June 2026, supports a framework integrating Graph Convolutional Networks and Long Short-Term Memory units for traffic forecasting with a reinforcement learning module for adaptive signal control.

Use Cases

• Benchmarking traffic forecasting models based on the described GCN-LSTM-Transformer architecture
• Evaluating adaptive signal control policies based on the reinforcement learning optimization module
• Analyzing the impact of edge-cloud data fusion on traffic state estimation and simulation
• Studying the robustness of predictive models to missing and noisy sensor data conditions

Strengths

• Experimental evaluation demonstrated a 17% reduction in average vehicle waiting time.
• The framework showed significant improvements in forecasting performance measured using MAE and RMSE.
• The proposed architecture is described as scalable and low-latency.

Limitations

• The dataset is very small at 5.5 KB, indicating limited scope.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
