Abstract :
The traditional GIS-based network data model did not adapt to the lane-based traffic analysis or simulation. A lane-based network data model is presented here. It uses lanes as the primitive topological objects of data model, of which geometry depends on itself. The basic topology of traffic network is composed of a set of lanes and nodes. The complex topologies between lanes are represented by the feature-based modeling method. Intersection in the traffic network is described as the polygon feature that has many virtual lanes in it. In the end, micro traffic flow simulation software based on GIS is developed, which adopts the lane-based network data model
