Abstract
The road network in the real world has been showed by the road network model based on node joint, which shows more and more limitations and greatly weakens the control of navigation system. It is the first time that a novel road network model,that is,the road network model based on virtual node joint,was presented in the paper to eliminate the limitations. The novel model adops virtual node to show multi-road converging area,and the virtual node is an area which is made up of converging roads first or last point,and has the same shape as road crossing. The novel model has better of image the traffic flow on the road network than the old model based on node joint,and satisfies the demand of the map matching theory better. Moreover,the novel model can be applied to traffic planning,traffic management planning,and traffic flow simulation.
