Abstract
In order to obtain a traffic flow when a specific condition is given to a target transportation network, transportation condition data which is data representing time constraints of traveling by first transportation means whose operation is not scheduled, a transportation parameter which is a parameter related to an operation of second transportation means whose operation is scheduled, and a travel demand which is data representing the number of traveling users for each desired arrival time and destination are respectively acquired. In addition, a template for generating a mathematical model representing travel of users between nodes is stored. By applying the transportation condition data, the transportation parameter, and the travel demand to the template, a mathematical model representing travel of users between nodes is generated. A traffic flow is obtained by solving an optimization problem that is formulated by the mathematical model.
