Abstract: Energy and traffic are the two core issues in the development of human society. As the number of electric vehicles keeps rising, the two artificial systems,namely electric power system and transportation system,will be integrated through deep interaction, making up the complex cyber-physical-social system. And massive heterogeneous electric vehicle users will also be involved. To make the urban integrated electric power and traffic network（IETN） operate in a safe, economical and reliable status,various methods including control and price signals can be used based on data acquired by information collection. In this paper,coordination of urban IETN is described from the perspective of system interconnection. The current situation and future potentials are discussed from the aspects of development trends, technology and policy, architecture and operation, key technologies and existing problems. By integrating wireless sensing technology into IETN, the operation status of eclectic vehicle users could be monitored and controlled through information collection, analysis and optimization and signal transmission. Thus, the integrated network could have improvement in various aspects such as overall energy efficiency, operation service capacity and congestion status.
