| Abstract: | Firstly, this paper analyzes the significance of road network model based on grid, and puts forward the structure of the model. Then, taking road-network in Hubei as an example, the paper introduces the simulation technologies of road shape and attributes, driving speed, and shortest driving path and driving time. Finally, the prospect of the model is analyzed, and the efficiency of the model is tested through the simulation of city affective intensity. |
