Abstract: The boosting of urbanization process in Beijing, as well as the increasing vehicle ownership and traffic demands, have brought serious traffic problems and related issues such as excessive energy consumption, exhaust emissions and noise pollution. The low traffic economic efficiency directly impacts the coordinated development of the city. The traditional roadstyle development model can no longer meet the needs of urban development. While the intelligent transportation technology and intelligent management are proven to be effective ways to improve the urban road traffic system on the synergistic development. Based on the largescale system theory, grey system model and the coordinated development principle, the paper explores the synergistic development of road traffic system and socioeconomic system, energy system as well as environment system. It then investigates road traffic system’s internal synchronous development capability by the GM model and analyzes the current situation of Beijing road traffic system. The results provide reference for optimizing the development of Beijing urban road traffic structure and promoting construction of intelligent transportation system.
