A Model of the Dynamic Traffic Road Network

Combining with the basic idea of object-oriented modeling and modules modeling, according to the hierarchical relationships, the entities in the road network are abstracted as layer independent hierarchical model. A static and dynamic combination of generalized urban road network model is established. Road and road relationship sub-model of generalized road network model and the data structures information are analyzed. Moreover, real-time traffic information is taken into account, which lays the foundation for the study of dynamic path planning.
