Large‐scale, fully automated, and comprehensive spatiotemporal pavement crack evaluation incorporating geographic information system, street view images, deep learning, and cluster analysis

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 30, Page 5867-5890, 19 December 2025.
Abstract Automatic condition assessment of road pavements is important for efficient pavement management. Most previous studies targeted highway, national, and state road routes and adopted their own imaging vehicles to evaluate pavement conditions. This study focuses on street view images for large‐scale, fully automated, and comprehensive condition ...
