To provide a technique for suppressing the last-minute crossing at a railroad crossing or to provide a technique for supporting the suppression of last-minute crossing.SOLUTION: A railroad crossing alarm auxiliary system 1 is configured to: acquire railroad crossing time table information 70 which is a time table of a railroad crossing alarm prediction time based upon a highly accurate time of a railroad crossing from a railroad crossing control system 40; generate timing information 80 of signal display at the highly accurate time on the basis of the railroad crossing time table information 70; and send the generated information to an auxiliary signal machine 20 installed at a position away from the railroad crossing by a predetermined distance. The timing information 80 is generated so as to display a period from a start prediction time to an end prediction time of a railroad crossing alarm at a red signal, display a period of the predetermined number of seconds just before the start prediction time of the railroad crossing alarm at a yellow signal, and display a period other than them at a blue signal. In addition, the railroad crossing alarm auxiliary system 1 generates recent alarm prediction time information 94 of the railroad crossing at a high accurate time on the basis of the railroad crossing time table information 70 and provides it to an automobile together with travel support information 90.SELECTED DRAWING: Figure 7

    【課題】踏切における直前横断を抑止させるための技術を提供すること、或いは、直前横断の抑止を支援するための技術を提供すること。【解決手段】踏切警報補助システム1は、踏切制御システム40から、踏切の高精度時刻に基づく踏切警報予測時刻のタイムテーブルである踏切タイムテーブル情報70を取得し、踏切タイムテーブル情報70に基づいて、高精度時刻での信号表示のタイミング情報80を生成し、踏切から所定距離離れた位置に設置された補助信号機20に送信する。タイミング情報80は、踏切警報の開始予測時刻から終了予測時刻までの期間を赤信号表示、踏切警報の開始予測時刻の直前、所定秒数の期間を黄信号表示、これら以外の期間を青信号表示とするように生成する。また、踏切警報補助システム1は。踏切タイムテーブル情報70に基づいて、高精度時刻での踏切の直近警報予測時刻情報94を生成して、走行支援情報90に含めて自動車に提供する。【選択図】図7
