摘　　要：为对综合交通枢纽安全进行评价,从人员因素、设备因素、行人设施、交通组织和环境因素5个方面识别影响枢纽安全的关键因素,建立枢纽安全评价指标体系;在利用AHP确定不同指标常权重的基础上,利用专家打分法评估指标安全状态,根据指标状态对常权重进行变权处理,建立基于变权模糊petri网的综合交通枢纽安全风险评价模型,设计相应的形式化推理算法,使推理过程更加简单、方便;以成都市某综合交通枢纽为实例进行安全评价,得出枢纽站的风险等级为安全。In view of the important position of integrated transportation hub in urban traffic system, assessing the safety state morerapidly and accurately is of great significance for the security of integrated transportation hub. This paper discriminates the key factorsthat influencing the hub safety from five aspects ： human factors, equipment factors, pedestrian facilities, traffic organization, and environmental factors. On the basis of using AHP to determine the constant weights of different indexes, the weights were altered accordingto the index safety states. An integrated transport hub security state assessment model was established based on variable weight fuzzypetri net, which makes the conclusion more objective and precise. Formal reasoning algorithm was given to simplify the reasoningprocess. In order to verify the validity of the model, a certain integrated transfer hub was taken as an example and the evaluation resulindicates that the risk level of the hub is safe.
