Abstract: Globally, the rapid urbanization process has led to a significant surge in energy demand, presenting an unprecedented challenge to existing road network systems. To address this challenge, integrating energy technologies into road systems has become a crucial strategy to solve energy issues and promote the rapid development of energy integration. Based on this, this paper focuses on road solar energy collection, road kinetic energy collection, road geothermal energy collection, and road wind energy collection technologies, using the composition and energy distribution of road energy systems as the starting point. In the section on road energy management and integration, the architecture and functions of the road energy management system were detailed, and the implementation methods of various energy integration technologies and their applications in road systems were discussed. Finally, the current research status of road energy technologies was summarized, and future development trends were anticipated. This work can provide valuable references and insights for the promotion and application of road and energy integration technologies.
