Regional ecological pattern and process are influenced by the existence and extension of road networks.

The road traffic network is an essential component of the whole urban spatial morphology.

Small world model provides a new aspect and method for exploring the topological structure and intrinsic characters of urban road network.

So,the researching results of the theory are unsuitable for urban road network.

The delay at nodes is considered in the equilibrium assignment model special for urban road network, which is closer to the real case of urban road network and better than other common assignment models.

Study on road network model based on virtual node joint

After reviewing the up-to-date road network models and analyzing the critical limitations,the next generation model is proposed,which is characterized by ① the real lanes are considered as the basic modelling primitive;② the 3D lane-to-lane topology is generated;and ③ comprehensive analysis and realistic visualization are available.

In order to reduce computational burden, this paper develops a new algorithm based on stored data from the road network model of hierarchical and spatial decomposition.
