図10を参照して、本実施形態3に係わる交通監視装置30の動作の第2の例を説明する。図10は、交通監視装置30の各部が実行する処理の流れを示すフローチャートである。
本実施形態の構成によれば、取得部11は、車両が映った時系列の画像データを取得する。測定部12は、時系列の画像データを用いて、車両の速度を測定する。制御部13は、車両の速度が規定範囲内である場合、車両と対面する交通信号機を、進行許可の灯色になるよう制御する。
前記実施形態1~3では、十字路での交通信号機の制御を説明したが、三叉路や多叉路であっても、交通信号機およびカメラの数が変わるだけで、十字路と同様に処理することができる。
前記実施形態1~3で説明した交通監視装置10,20,30の各構成要素は、機能単位のブロックを示している。これらの構成要素の一部又は全部は、例えば図11に示すような情報処理装置900により実現される。図11は、情報処理装置900のハードウェア構成の一例を示すブロック図である。
