Optimal Model for Pavement Management Systems
Explore the spatial distribution of International Roughness Index (IRI) and Pavement Condition Index (PCI) data across the Nizwa-Muscat and Muscat-Nizwa routes, revealing key insights into road surface smoothness and structural health, visualized using the Jenks classification method in ArcGIS Pro 3.3.
1.849
Avg. IRI (Nizwa-Muscat, m/km)
The average IRI for the Nizwa-Muscat route was 1.849 m/km, indicating good to excellent ride quality. Lower values suggest smoother pavements, contributing to acceptable comfort levels for road users.
78.49
Mean PCI (Nizwa-Muscat)
With a mean PCI of 78.49, the Nizwa-Muscat route generally shows sound structural condition. However, localized segments with PCI as low as 51.36 indicate areas needing targeted, more intensive maintenance to prevent further deterioration.

An overview of the Machine Learning models' performance in predicting PCI, emphasizing the strengths of ensemble methods and identifying areas for improvement in less effective models.
PCI Model Performance Summary
The analysis confirms the dominance of ensemble methods (Adaboost and RF) in PCI analysis, achieving perfect scores (100% across all metrics) during validation. The Decision Tree (DT) model also showed near-perfect performance with 99.9% AUC and 99.5% MCC, maintaining stability. While ANN showed slight improvement, it lagged overall. In contrast, SVM consistently underperformed, with validation scores of 0% MCC and 56.2% Precision, indicating its unsuitability for PCI prediction tasks.
Delve into the robust evaluation of ML models using confusion matrices, box and whisker plots, and noise sensitivity analysis to understand their reliability and consistency under various conditions.
Confusion Matrix Insights
All models struggled with Poor pavement classification. SVM particularly misclassified Poor as Very Good (159 instances), showing a tendency to overestimate quality. RF had challenges with underrepresented classes, while ANN over-predicted Good conditions. This highlights the need for targeted feature engineering and data balancing.
Box and Whisker Plot Analysis
The ANN model outperformed others with a median accuracy of 0.87 (0.84-0.89 range), closely followed by AdaBoost (0.86 median). RF and SVM, while stable, showed relatively lower median accuracy (0.76). This indicates ANN and AdaBoost offer superior consistency and accuracy.
Noise Sensitivity Insights
All models showed accuracy degradation with increasing noise. SVM demonstrated the highest noise tolerance, with initial accuracy of 0.78 falling to 0.72. ANN, DT, and AdaBoost started with higher accuracy (around 0.90) but showed a more gradual decline to 0.82. This suggests SVM's resilience despite lower initial performance, while ensemble methods offer higher baseline accuracy.
