中文摘要	A spatial and temporal hierarchical model was developed for area traffic state analyses to predict area traffic states. The state analysis defines the different cut-values for traffic jams and partition intersection states into different hierarchies for the spatial and temporal hierarchical model. The model can represent micro-, meso-, and macro-traffic parameters with the spatial and temporal information and traffic state information for automatic traffic state analyses. Simulations show that the hierarchical model can partition intersections according to the traffic state of the intersections and the links of the traffic network. The intersection reachability, the link connectability and the network state can be deduced from the model. The model can be used for automatic analyses of area traffic networks and for vehicle route guidance and traffic control systems.
