摘要: 为研究危险货物在城市快速道路运输过程的动态运输风险,基于现有的危化品运输监管技术动态参数,分析了运输动态因素、城市快速交通流特征和运输风险这3者的相关性,建立了城市快速道路危险货物运输动态风险评价模型,重点研究了交通流参数对危险货物事故概率和人口暴露量的影响。实例结果表明:不同车速对运输风险影响显著,该模型可实时评估城市快速道路危险货物运输动态风险,对加强危险货物运输风险监管力度,降低运输风险有现实意义。

Abstract: In order to study dynamic transportation risks of dangerous goods in the process of urban freeway transportation, based on the current available dynamic parameters of the dangerous chemicals transportation supervision technology, the correlation among transportation dynamic factors, characteristics of urban traffic flow, and transportation risks was analyzed, and a dynamic risk evaluation model of dangerous goods transportation on urban freeway was established. The influence of traffic flow parameters on accident probability of dangerous goods and population exposure was focused. The results of case study show that the vehicle speed exerts significant influence on transportation risks. The proposed model is of great practical significance to assess dynamic risks of dangerous goods transportation on urban freeway in real time, strengthen the supervision of dangerous goods transportation risk, and reduce transportation risks.

Key words: traffic and transportation engineering, urban freeway, dangerous goods, transportation risks, dynamic model
