Multimodal Supported Composite Transportation Network Model

A multimodal composite transportation network model is developed in response to the multimodal travel requirement of travelers.A geometrical snapping model is presented for building the topology of multimodal composite network and the relative topology build algorithm is put forward based on this model.The model unites sub networks of different modes into a integrate graph structure,which provides the efficient data structure for multimodal route analyze.Experiment results demonstrate that the data model and algorithm are viable.
