To smooth a flow of vehicles in relative to a case where the flow of vehicles is identified from traffic of a main road, when controlling switching of signals within a road network.SOLUTION: In accordance with a traffic light switching control device (12), in a signal control optimization unit (126), traffic information of a road network stored in a traffic information storage unit (123) is acquired via a related information extraction unit (124), switching timing of each of signals (SG1-SGN) installed in intersections is optimized while taking a main road connected to an intersection and a peripheral road connected to the other adjacent intersection into account by a computing element that is constructed by data from an optimized data storage unit (125), and information indicating the optimized switching timing is outputted to the signal. Thus, a vehicle traveling on a road included in the road network can be smoothly traveled, and a flow of vehicles in the road network is smoothed.SELECTED DRAWING: Figure 1

    【課題】道路網内の信号機を切替制御する場合に、主要な道路の交通量から車両の流れを特定する場合に比べて、車両の流れを円滑にする。【解決手段】信号機切替制御装置(12)は、信号制御最適化部(126)で、交通情報蓄積部(123)に蓄積した道路網の交通情報を関連情報抽出部(124)を介して取得し、最適化データ保存部(125)からのデータにより構築された演算器で、交差点に連結した主要道路及び隣り合う他の交差点に連結した周辺道路を考慮して交差点に設置された信号機(SG1〜SGN)各々の切替タイミングを最適化し、最適化した切替タイミングを示す情報を信号機へ出力する。これにより、道路網に含まれる道路を走行する車両は円滑に走行でき、道路網の車両の流れを円滑にすることができる。【選択図】図1
