To provide a collision prevention system capable of more reliably preventing an intersection collision between a vehicle and a person or between vehicles than before.SOLUTION: A collision prevention system 1 includes: a portable terminal 20 carried by a pedestrian W; an on-vehicle terminal 10 mounted on a vehicle C; and repeaters 30 arranged on a road. The terminals 10, 20 include radio wave output sections 11, 21 for outputting a feeble radio wave. The repeater 30 includes: a repeater side detection section 31 for detecting a position of the pedestrian W or the like based on the feeble radio wave output within an area AR; and a position information output section 32 for outputting information related to the detected position. The terminal 10 also includes: a vehicle side detection section 12 for detecting the position of the pedestrian W or the like based on the feeble radio wave output within an area AC; and a position information display section 13 for performing displaying related to the position of the pedestrian W or the like on a windshield based on both of the position detected by the vehicle side detection section 12 and the position included in the information output from the position information output section 32.SELECTED DRAWING: Figure 1

    【課題】車両と人または車両同士が出会いがしらに衝突するのを従来よりも確実に防止することができる衝突防止システムを提供する。【解決手段】衝突防止システム1は、歩行者Wが携帯する携帯端末20と、車両Cに搭載された車載端末10と、道路に設置された中継器30とを備え、端末10,20は、微弱な電波を出力する電波出力部11,21を有し、中継器30は、エリアAR内で出力された微弱な電波に基づいて歩行者W等の位置を検出する中継器側検出部31と、検出した位置に関する情報を出力する位置情報出力部32とを有し、端末10は、エリアAC内で出力された微弱な電波に基づいて歩行者W等の位置を検出する車両側検出部12と、車両側検出部12が検出した位置および位置情報出力部32が出力した情報に含まれる位置の両方に基づいて歩行者W等の位置に関する表示をフロントガラス上に行う位置情報表示部13とをさらに有する。【選択図】図1
