To support priority traveling of an emergency vehicle while achieving traveling smoothness and safety of the emergency vehicle.SOLUTION: An emergency vehicle travel support device 20 includes: a road width reduction positional point specification unit 212 for specifying a road width reduction positional point where a road width becomes narrow on a travel schedule route of the emergency vehicle; and an intersection specification unit 213 for specifying a signal intersection where a road including the road width reduction positional point is connected in front of a traveling direction of the emergency vehicle as a closing intersection. The emergency vehicle travel support device makes a traffic signal relating to a passage direction of an emergency vehicle light a green signal to perform an instruction of making the traffic signal relating to a direction of preventing passage of the emergency vehicle light a red signal with respect to a traffic signal installed at the closing intersection, and makes the traffic signal relating to the passage direction of the emergency vehicle and the traffic signal relating to the direction of preventing passage of the emergency vehicle light red signal with respect to a traffic signal arranged at a signal intersection that does not correspond to the closing intersection.SELECTED DRAWING: Figure 3

    【課題】緊急車両の走行の円滑性および安全性を両立させながら、緊急車両の優先的な走行を支援する。【解決手段】緊急車両走行支援装置20は、緊急車両の走行予定ルート上において、道路の幅員が狭くなる幅員減少地点を特定する幅員減少地点特定部212と、幅員減少地点を含む道路が緊急車両の進行方向の前方で接続する信号交差点を閉塞交差点として特定する交差点特定部213と、閉塞交差点に設置された信号機に対して、緊急車両の通過方向に係る信号機に青信号を点灯させ、緊急車両の通過を妨げる方向に係る信号機に赤信号を点灯させる指示を行い、閉塞交差点に該当しない信号交差点に設置された信号機に対して、緊急車両の通過方向に係る信号機および緊急車両の通過を妨げる方向に係る信号機に赤信号を点灯させるよう構成されている。【選択図】図3
