To provide a technology for more safely supporting traveling of across a crosswalk for an automatic travel device.SOLUTION: A crossing support system 1 supports, in a crosswalk installed with a pedestrian signal 20, an automatic travel device 10 to travel across a crosswalk When reaching the crosswalk that is applied with the crossing support system 1, the automatic travel device 10 transmits a crossing determination request signal to the pedestrian signal 20. When receiving the crossing determination request signal from the automatic travel device 10, a processing unit 22 of the pedestrian signal 20 determines whether or not crossing is possible based on a display status (red signal or blue signal) of the pedestrian signal 20 and a remaining time of the blue signal, and transmits a crossing instruction to the automatic travel device 10 when the crossing is permitted, but transmits a stop instruction to the automatic travel device 10 when the crossing is impossible. The automatic travel device 10 executes the crossing at safe timing based on the crossing instruction or the stop instruction from the pedestrian signal 20.SELECTED DRAWING: Figure 1
【課題】自動走行装置に対しより安全に横断歩道の走行を支援する技術を提供する。【解決手段】横断支援システム1は、歩行者用信号機20が設置された横断歩道において自動走行装置10に対し前記横断歩道の走行を支援するものである。自動走行装置10は、横断支援システム1が適用された横断歩道に到着した時点で横断判定要求信号を歩行者用信号機20に送信する。歩行者用信号機20の処理部22は、自動走行装置10から横断判定要求信号を受信すると、歩行者用信号機20の表示状況(赤信号か青信号か)や青信号残り時間に基づいて横断の可否を判定し、横断可の場合には自動走行装置10に横断指示を送信し、横断不可の場合には自動走行装置10に停止指示を送信する。自動走行装置10は、歩行者用信号機20からの横断指示又は停止指示に基づいて安全なタイミングで横断を実行する。【選択図】図1
