Abstract
In recent years,public health incidents have occurred frequently both domestically and internationally,posing a severe challenge to the world's emergency response capabilities.To improve the emergency response capabilities of highways in the event of public health emergencies,reduce public health threats and economic losses.This article divides sudden public health incidents into three stages:Before,during,and after the event.Combined with the four processes of prevention,preparation,response,and recovery in emergency management,the emergency capacity of highways is divided into emergency preparedness capacity,emergency response capacity,and emergency recovery capacity,corresponding to each stage of public health incidents.Based on the wide range,urgency,unpredictability,harmfulness,and complexity of sudden public health emergencies,relevant literature and policy documents were consulted through text mining,Delphi method,and expert interviews.Finally,17 factors affecting the emergency response capacity of highways under sudden public health emergencies were identified and extracted,And the scientific and rationality of the 17 influencing factors were verified through expert authority coefficient and Kendall coordination coefficient tests.A factor analysis model based on the order relationship entropy weight method decision experiment and evaluation experiment method was constructed.Firstly,the subjective and objective weights of the factors were calculated using the G1-EW subjective and objective weighting method,and then the combination weights of the factors were calculated using the Lagrange multiplier method.Based on the global weight ratio between the factors,a DEMATEL direct impact matrix can be constructed to obtain a comprehensive impact matrix,Calculate the centrality and causality of each factor.In this study,a temporary emergency decision-making group was formed by inviting 10 experts from relevant fields.Each expert evaluated and ranked the importance of 17 factors based on the principles of fairness,impartiality,and reasonableness.Finally,the various values of each factor were calculated through the constructed model,and 8 causal factors(causal degree greater than 0)were classified based on the causal degree values.These factors have a significant impact on other factors and 9 outcome factors(with a causal degree less than 0)indicate that these influencing factors are more influenced by other factors.According to the order of centrality,five key influencing factors are identified:prevention and control information disclosure,emergency rescue command and coordination,vehicle operation recovery,emergency material reserves,and green emergency channel setting.The establishment of these key factors plays a very important role in improving the emergency response capacity of highways under sudden public health emergencies.Based on the three different stages of sudden public health emergencies,the focus is on controlling these five key factors,and propose corresponding response measures for each stage.The 17 influencing factors identified through research and analysis in this article can provide scientific and reasonable reference basis for future research and analysis of related factors.At the same time,the proposed analysis model can provide a new idea for the selection of factor research methods in the future.The research results can provide theoretical support for improving the emergency response capacity of highways in the event of public health emergencies in the future,and apply theoretical knowledge to practice.关键词
