Modeling and Implementing Research of Multimodal Transportation Network

To satisfy the needs of a variety of demand-responsive transport, the multimodal transportation problem appeared. This paper focuses on network modeling with a hierarchical structure. The relationship between different levels is described in detail, and dynamic segmentation and linear referencing techniques are used to solve the overlay problem in multimodal network. Furthermore, a shortest path algorithm is proposed to solve the transfer problem with several public vehicle modes. Finally, the results simulated by Geographic Information System (GIS) are given to demonstrate the effectiveness of the proposed model and algorithm.
