PROBLEM TO BE SOLVED: To provide a traffic signal control machine and a traffic signal control method that causes no contradiction in display order of signal colors even in a case of switching to indications different from a plurality of indications whose display order is previously determined.SOLUTION: A traffic signal control machine comprises: a storage unit storing one or plurality of specific indications composed of a plurality of steps of traffic signal colors such that display order of a plurality of indications indicating flow passages given passing right at an intersection with a blue sign, and composed of a plurality of steps of traffic signal colors such that passing right different from the plurality of indications is given; a display determination unit which determines whether a specific indication can be displayed right after an arbitrary indication when an arbitrary indication being displayed among the plurality of indications is switched to one or a necessary specific indication among the plurality of specific indications stored in the storage part; and a switching unit which switches the arbitrary indication to the specific indication when it is determined that the display is possible.SELECTED DRAWING: Figure 1
【課題】予め表示順序が定められている複数の現示と異なる現示に切り替える場合でも信号灯色の表示順序に矛盾を生じさせない交通信号制御機及び交通信号制御方法を提供する。【解決手段】交通信号制御機は、信号灯色の複数の階梯で構成され、青信号で交差点での通行権が付与される流路を指す複数の現示の表示順序が予め定められ、信号灯色の複数の階梯で構成され、複数の現示それぞれと異なる通行権が付与される1又は複数の特定現示を記憶する記憶部と、複数の現示のうちの表示中の任意の現示を記憶部に記憶した1又は複数の特定現示のうちの所要の特定現示に切り替える場合、任意の現示の次に特定現示の表示が可能か否かを判定する表示判定部と、表示が可能であると判定した場合、任意の現示を特定現示に切り替える切替部とを備える。【選択図】図1
