Abstract
The advancement of Transportation Systems Management and Operations (TSMO) marks a fundamental reorientation in how transportation infrastructure is managed throughout the United States. Confronted with growing congestion, deteriorating assets, and heightened calls for sustainable mobility, urban regions are turning to TSMO as a strategic alternative that emphasizes operational efficiency, technology integration, and data-driven management over conventional infrastructure expansion. This literature review synthesizes the historical trajectory of TSMO, the pivotal role of Intelligent Transportation Systems (ITS) and signal optimization technologies, and the ongoing challenges related to data utilization and performance measurement. It also examines the transformation of Traffic Management Centers (TMCs) into proactive, multimodal coordination hubs. Drawing from federal policy frameworks, state-level initiatives, and regional case studiesincluding the Florida DOT District 4 Traffic Operations Centerthis review underscores the institutional, technological, and strategic progress shaping contemporary TSMO practices. It concludes by identifying enduring barriers and proposing future research priorities essential to advancing a more resilient, integrated transportation operations ecosystem.
