Pavement Condition Index Lake Township 2025

This pilot program dataset provides Pavement Condition Index (PCI) values for roadway segments within the following townships: Barrington, Bloom, Lake, Palos, Stickney, and Thornton. PCI is a numerical rating of pavement condition based on the type and severity of distresses observed on the pavement surface, where 0 represents the worst possible condition and 100 represents the best possible condition. Roads were divided into segments with a maximum length of 0.25 line miles per segment; segments longer than 0.25 miles were split into equal-length sub-segments. Each segment is assigned an average PCI value derived from higher-resolution PCI point data by associating PCI score points within a maximum distance of 20 feet from the roadway segment and calculating the segment-level average.
