| Abstract: | Aiming to resolve the problem of microscopic simulation model of road network, a modeling approach of network based on G1S is presented on this paper. According to this model, the data structure of micro-simulation network is implemented. First, the micro-simulation network model is built according to the characteristics of GIS and the demand of traffic microsimulation system, and then, the data structure of the road network was realied comes true according to the model and specific computer language. |
