In response to the proposal of Transit-Oriented development, and promoting comprehensive transportation efficiency. As a key facilities of transportation system, transit hubs are designed to provide switching point for multimodal transport. Aiming at minimize comprehensive travel costs, the paper proposes an optimal location model for integrated design of transit hub and inter-link layout in a multimodal network, which considering the regional geographic characteristics and administrative division features. In order to solve the nonlinear optimization model with discrete variables, an improved genetic Algorithm established. A design example is given to verify the validity of the model, and the result shows that the performance of comprehensive passenger hub is significant improved. Meanwhile, by introducing geographical attribute, the model can effectively and realistically capturing the interaction between traffic demand and land use.
