Pavement Condition Index for 5,200 Lane Miles of Roadways

Biennially updated data from the Montgomery County Department of Transportation analyzes conditions across all 5,200 lane miles of county roadways. The Pavement Condition Index (PCI) provides a numerical score from 0-100, derived from an analysis of 19 discrete pavement distresses like cracking and potholes. This dataset enables systematic assessment of pavement quality for maintenance planning.

Use Cases

• Predict future PCI scores for road segments using historical data on StreetName, Segment_ID, and SurfaceTyp.
• Analyze correlations between pavement distress types and PCI ratings to identify primary failure modes.
• Prioritize road maintenance schedules by ranking segments based on PCI, Width, and Length_1.
• Map pavement condition spatially using the_geom to visualize geographic clusters of poor infrastructure.
• Assess maintenance depot performance by comparing average PCI scores grouped by DEPOT_NAME or DEPOT_NUMB.

Strengths

• Covers 5,200 lane miles of roadways within a defined county.
• PCI scores are derived from a standardized analysis of 19 specific pavement distress types.
• Data is updated on a biennial schedule, providing regular snapshots.

Limitations

• The exact number of records (rows) is unknown, making scale assessment difficult.
• Sample data is unavailable, preventing verification of data structure and value ranges.
• Specific license terms are unknown, which may restrict commercial use.
