| Methodology | Balanced Accuracy | Major Recall (TPR) | Key Advantages |
|---|---|---|---|
| RDPVR (Random Data Partitioning with Voting Rule) | 58% | 51% |
|
| RDPVR with XGBoost Base Classifier | 63% | 63% |
|
| XGBLF (XGBoost with Balancing the Loss Function) | 54% | 95% |
|
| BRF (Balanced Random Forest) | 61% | 39% |

Normalized Importance of Speed (SHAP)
Speed is identified as the single most critical factor contributing to major pedestrian accident risk. This highlights the urgent need for enhanced speed management strategies.
Case Study: Jordan's Improving Safety Trajectory
Our interpretability analysis, specifically the Year feature, reveals an encouraging trend: major accident risk in Jordan has measurably decreased in recent years (2020–2023) compared to 2014–2016. This finding suggests that recent policy changes and infrastructure improvements are having a tangible impact on pedestrian safety outcomes.
This insight is unique, as most traffic safety research does not treat 'Year' as a predictive variable. The decline in major accidents, despite an annual increase in vehicles and pedestrians, indicates effective governmental interventions such as significant traffic fine increases for serious violations.
Implication for Business: This demonstrates the potential for data-driven policies to yield positive results. Enterprises can leverage similar AI-driven trend analyses to validate the effectiveness of their safety initiatives and infrastructure investments over time, ensuring continuous improvement and resource optimization.
Data-Driven Recommendations for Amman's Traffic Authorities
Based on our robust interpretability analysis, we propose targeted interventions to enhance pedestrian safety:
- Speed Control: Implement automated speed cameras on high-risk corridors, especially during peak hours (7 a.m. onwards), as speed is the major risk factor (SHAP: 1.00).
- Infrastructure Investment: Prioritize improving road geometry on "curved and level" sections, which show the largest risk contribution (SHAP: +0.874).
- Heavy Vehicle Regulation: Enforce stronger restrictions and mandatory speed limits for "Truck Tractor (Non-Freight)" vehicles due to their high-risk contribution (SHAP: +0.618).
- Lighting Upgrades: Prioritize LED lighting enhancements in "darkness" conditions, particularly at junctions and pedestrian crossings, where poor lighting significantly increases major accident risk.
- Behavioral Interventions: Target "High-Risk and Dangerous Behavior" violations (SHAP: +1.091) with increased fines and mandatory safety education programs.
Strategic Impact: These recommendations translate technical AI insights into concrete, actionable policies, enabling transportation authorities to make evidence-based decisions, optimize resource allocation, and proactively mitigate risks in high-risk zones, ultimately reducing pedestrian injury severity.
