Traffic condition prediction system and traffic condition prediction method

摘要

PROBLEM TO BE SOLVED: To provide a traffic condition prediction system capable of predicting a road traffic condition with high accuracy in the future even if the number of vehicle detection devices for measuring the number of passing vehicles is small. A traffic condition prediction system includes a traffic condition estimation unit, an inflow traffic volume prediction unit, a reference cumulative traffic volume prediction unit, a most downstream pseudo cumulative traffic volume prediction unit, and a traffic condition prediction unit. The traffic condition estimation unit estimates the traffic condition of the road. The inflow traffic forecasting unit predicts the inflow of vehicles flowing into the reference point. The standard cumulative traffic forecasting unit acquires the standard cumulative traffic forecast value at the most upstream reference point of the forecast target range for predicting road traffic volume based on the traffic condition estimation result and the vehicle inflow prediction result. To do. The most downstream pseudo cumulative traffic forecast unit predicts the most downstream pseudo cumulative traffic forecast value at the most downstream point of the prediction target range based on the standard cumulative traffic forecast value. The traffic condition prediction unit predicts the traffic condition of the road based on the standard cumulative traffic volume prediction value and the most downstream pseudo cumulative traffic volume prediction value.
