Combinatorial Evaluation for Forewarning Grade of Emergency in Urban Mass Transit
Jia Gao, Ruihua Xu, Jiang Zhibin · 2010
To evaluate the forewarning grade of emergency in urban mass transit comprehensively, a new combinatorial method combined with color warning was proposed. The evaluation factors which could influence the emergency were divided into external factors and internal factors. External factors were mainly decided by the evacuation wave in stations. Internal factors mainly included Interrupt Time, Casualties, Happen Position, Property Loss and Sphere of Influence. These internal factors constituted an evaluating indicators system. The results demonstrate that the combinatorial evaluation not only fulfills the comprehensive safety assessment for emergency in urban mass transit, but also catches the emphases in different situations.
