Abstract:Construction waste transportation (CWT) is a tightly regulated urban activity central to urban development, traffic operations, and environmental governance. As an underexamined yet policy-sensitive segment of intra-city freight transportation, CWT exhibits complex operational logics that warrant systematic analysis for effective supervision and management. This study adopts a dynamic complex network perspective, leveraging large-scale GPS data from over 8,000 construction waste transport trucks in Chengdu, China. Dynamic community detection is applied to characterize the temporal evolution of network structures, revealing a clear two-phase daily operational pattern and community structures dominated by different transportation enterprises. In addition, a motif-based node importance identification method tailored to CWT networks is developed to uncover critical motifs and structurally important nodes. These insights provide managerial guidance for regional governance of construction waste transport and targeted supervision of key nodes within urban transportation networks.
