To provide an event occurrence probability analyzer and an event occurrence probability analysis method for reducing a processing load on calculation processing to analyze a traffic state having a higher probability of occurrence of a predetermined event.SOLUTION: A server device 1 as an event occurrence probability analyzer in an accident prediction system S includes: a distribution information generation section 12; and an accident ratio calculation section 13 as an event occurrence ratio calculation section. The distribution information generation section generates distribution information obtained by mapping traffic information expressing a traffic state for each predetermined time unit based on a past event occurrence record and multiple analysis indexes. The event occurrence ratio calculation section calculates each one of event occurrence ratios of multiple division units obtained by dividing distribution information for each one of predetermined units of multiple analysis indexes.SELECTED DRAWING: Figure 1

    【課題】所定のイベントが発生する可能性が高い交通状況を分析する演算処理の処理負荷を低減したイベント発生確率分析装置およびイベント発生確率分析方法を提供する。【解決手段】事故予測システムSにおいて、イベント発生確率分析装置としてのサーバ装置1は、分布情報生成部12と、イベント発生率算出部としての事故率算出部13とを備える。分布情報生成部は、所定の時間単位ごとの交通状況を表す交通情報を、過去のイベント発生実績と、複数の分析指標とに基づいてマッピングした分布情報を生成する。イベント発生率算出部は、分布情報が複数の分析指標の各々の所定の単位ごとに分割された複数の分割単位の各々のイベント発生率を算出する。【選択図】図1
