Slovakia Road Surface and Passability Metrics for 9,400 km of Arterial Roads

Slovakia arterial road network analysis covering 9,400 km, featuring AI-derived surface and width attributes generated by HeiGIT from 2020 and 2024 PlanetScope imagery. The data combines OpenStreetMap (OSM) geometry with deep-learning predictions to assess logistical accessibility and infrastructure changes over a four-year period.

Use Cases

• Logistical routing using the Humanitarian Passability Index (HPI) to determine vehicle accessibility
• Infrastructure monitoring by tracking the Road Surface Change attribute to identify paving projects
• Emergency response planning using Road Width Class to identify potential bottlenecks for heavy trucks

Strengths

• 89.2% accuracy for surface model predictions
• Provides surface data for 33.7% of roads missing OSM surface tags
• Multi-temporal coverage comparing 2020 and 2024 conditions

Limitations

• Geographic scope limited to arterial road classes
• AI-derived attributes may have classification errors compared to ground truth
