The widespread advancement of autonomous vehicle (AV) technologies is accelerating the transformation of urban mobility systems and prompting a critical reassessment of pedestrian infrastructure. Among these, pedestrian crosswalks—long regarded as fundamental elements of walkable and safe cities—are increasingly positioned at the intersection of automated transport and human-centered urban design. This study conducts a comprehensive review of contemporary scholarship and emerging design practices to examine how AV development is reshaping the spatial configuration, functional role, and technological integration of pedestrian crosswalks. Drawing on interdisciplinary insights from urban planning, mobility studies, and environmental design, the paper explores evolving concepts such as shared street environments, sensor-enhanced crossing systems, and adaptive pedestrian interfaces. Particular attention is given to the implications for vulnerable groups and the broader goals of urban sustainability. The review ultimately argues for a renewed planning paradigm that envisions crosswalks not as static traffic infrastructure, but as active, adaptive components of a resilient and inclusive urban form.
