Abstract:This paper Analyses the problems of the domestic smart road construction and construction demands, and presents that smart road traffic city-level cloud platform is the core of the smart urban road network. This paper puts forward the overall scheme architecture, software function modules and operation management mode for the platform. Through the application of advanced digital technologies, the construction of city-level data center, the integration of software and hardware, the development and deployment of cloud platform, we can finally build a future-oriented intelligent road traffic system, with the digital empowerment of facilities management and maintenance, traffic control, emergency and decision-making.
