Summary:The invention relates to a method and a system for space and time analysis of urban road traffic states. On the basis of a space and time autocorrelation theory, a basic theory of mathematical statistics is applied, and according to the real-time traffic flow data of a road network, the space and time evolution of the traffic states and the generation, development and dissipation process of congestion are analyzed. The distribution features of different road states in space and time are subjected to statistical analysis by the method, the space and time rule of the evolution of the road traffic states of the urban road network is analyzed, the congestion rush hour in time and the bottleneck road in space are identified and judged, and the formulation and implementation of traffic measures are further supported.
