TRAFFIC-CONGESTION PREDICTION SYSTEM, TRAFFIC-CONGESTION PREDICTION METHOD, AND RECORDING MEDIUM

摘要

The present invention predicts with a high degree of accuracy whether traffic congestion will occur or not. A traffic-congestion prediction system 10 includes a traffic-state prediction unit 17 and a traffic-congestion determination unit 18. The traffic-state prediction unit 17 predicts the state of traffic at a specific prediction time at a specific prediction location, by using a prediction formula for predicting the state of traffic at the specific prediction location on the basis of the state of traffic at one or more locations. The traffic-congestion determination unit 18 determines whether or not traffic congestion will occur at the specific prediction time at the specific prediction location, on the basis of traffic-congestion determination information, which expresses the relationship between the state of traffic congestion and the state of traffic at the specific prediction location, and also on the basis of the predicted state of traffic at the specific prediction time at the specific prediction location.
