Implication

Analysis demonstrates nonlinear relationships impacting road traffic safety in three Chinese megacities, indicating complex interactions among built environment factors.

Key Points

Visual information from street view images significantly contributes 74.08% to road safety outcomes, highlighting its importance.
Points of Interest show a combined contribution of 13.77%, while road characteristics contribute only 12.16%.
Data analysis applied gradient boosting decision trees to assess nonlinear effects across built environment features.
Effects of built environment features on road safety appear complex, suggesting that planning should consider these interactions.
