The Safety Assessment And Analysis Of Beijing Subway Operation And Its Subsystem-Beaconage System

Line 1 and 2 of Beijing subway are the earliest subway in our country. Its safety has not been fully and thoroughly checked because of high cost in totally update and the perfect record of non-fault during the past 35 years. The safety hidden troubles caused by overage facilities gradually increase and the adjustment of the traffic structure calls for more to the subway operation, so it is urgent to define the situation of Line 1 and 2 of Beijing subway to carry out some safety measurement. And whether the work emphasis reflected by the world-wild subway faults should be also emphasized during our work depends on the analysis basing on the wholly safety assessment.Basing on the safety system engineering theory, real situation of Line 1 and 2 of Beijing subway and learning from the assessment index system of other subway abroad, this paper sets facility, management and fault in the view of hardware, software and result. Then it defines the 2nd and 3 rd indexes through the organization and responsibility analysis of sub system so as to build the 4-floored safety assessment index system. This is the first one that...
