MULTIMODAL TRANSPORTATION SYSTEM, MULTIMODAL TRANSPORTATION METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM STORING PROGRAM

A multimodal transportation system includes a creation unit that creates an itinerary including a movement route and a plurality of types of moving bodies moving along the movement route, and a proposal unit that outputs the itinerary to an external terminal. Based on the movement situation of the user and traffic information related to the movement by a first moving body, the creation unit changes a part of the itinerary that is related to the movement by a second moving body scheduled to be used by the user before the first moving body, and the proposal unit outputs the itinerary that has been modified to the external terminal.
