Traffic-congestion prevention system, traffic-congestion prevention method, and recording medium

A traffic-congestion prevention system comprising:

• a memory storing instructions;
• and
• one or more processors configured to execute the instructions to:
• calculate a target traffic state to be achieved at a current time, for each of a plurality of locations different from a traffic-congestion prediction location where occurrence of traffic congestion at a future time is predicted at the current time, in order to prevent the occurrence of the traffic congestion at the future time;
• and
• generate control information for realizing the target traffic state for each of the plurality of locations,
• wherein
• the target traffic state is displayed on a display means to be referred to by an operator of road management,
• the one or more processors configured to further execute the instructions to accept, from the operator, at least one of a modification instruction for the target traffic state displayed on the display means, a modification instruction for a function or a constraint equation for calculating the target traffic state, and a change instruction of a prediction model, and generate control information for realizing the target traffic state for each of the plurality of locations, and
• the target traffic state is at least one of a vehicle density and a number of passing vehicles per unit time to be achieved at a time, before a traffic-congestion prediction time at which occurrence of the traffic congestion is predicted, in order to prevent the traffic congestion.
