To provide a technique to perform switching of light color signals of a traffic light installed at an intersection with traffic-actuated control capable of preventing the occurrence of traffic jam on an approach to the intersection.SOLUTION: A traffic-actuated control signal output device acquires a vehicle travel situation on an approach to an intersection from vehicle detection data of vehicles traveling on the approach detected by a radar device scanning the approach by survey waves, and estimates the traffic situation on the approach. The traffic-actuated control signal output device stores, in a storage unit, an extension condition for extending switching of light color signals of a traffic light installed at the intersection for every traffic situation. The traffic-actuated control signal output device collates the acquired vehicle travel situation on the approach with the extension condition for the estimated traffic situation on the approach, determines whether to extend the switching of the light color signals of the traffic light at the intersection, and outputs a traffic-actuated control signal according to a determination result.SELECTED DRAWING: Figure 4
【課題】交差点に設置されている信号機の灯色信号の切り替えが、交差点の流入路で渋滞が発生するのを抑制できる感応制御で行える技術を提供する。【解決手段】感応制御信号出力装置は、レーダ装置が交差点の流入路を探査波で走査して検知した、流入路を走行している車両の検知データから流入路における車両の走行状況を取得するとともに、流入路の交通状況を推定する。感応制御信号出力装置は、交通状況別に、交差点に設置されている信号機の灯色信号の切り替えを延長する延長条件を記憶部に記憶する。感応制御信号出力装置は、取得した流入路における車両の走行状況を、推定された流入路の交通状況の延長条件に照合し、交差点の信号機の灯色信号の切り替えを延長するかどうかを判定し、判定結果に応じた感応制御信号を出力する。【選択図】図4
