Description
Summary:Transfer is the most obvious and important characteristic of intermodal and multimodal transport systems. In a Public Transport Information System (PTIS), the structure design of transfer data is the key point in building up the database of transit networks, for it not only concerns the efficiency of some main applications such as the shortest path search and the management of lines service, but also determines the design of Human-Machine Interface (HMI) which affects the efficiency of data access, management and maintenance. On the basis of the topology of the public transportation network defined by the European standard --TRIDENT, we propose 3 modes to organize the transfer data according to different constraints of data quantity, precision and accuracy. Finally, a conclusion is presented by the feedback of implantation and comparison.
