摘要
为更加准确和实时评估道路危险货物运输人员暴露风险,基于风险评价内容和危险货物运输卫星定位监管系统实时采集的车速和道路信息参数,建立高速公路危险货物运输人员暴露风险实时评价模型;重点研究了危险货物在高速公路运输过程中,平均车速分别与交通密度和高速服务区人员暴露量的函数关系,实时评价路上和人员密集区的人员暴露量,并考虑车型对平均车速的修正;实例分别对不同车速条件下和路过服务区时的运输风险进行评估。结果表明:车速和人员密集区对人员暴露风险影响显著,可进一步分解风险指标,提高风险评价的精度。同时该模型可实时评估运输动态风险,对辅助危险货物运输风险智能监管、降低运输风险有现实意义。
For more accurate real-time assessment of exposure risks of road transportation personnel of dangerous goods,a real-time evaluation model of exposure risks of highway transportation personnel of dangerous goods was proposed,which was based on the risk evaluation content,the vehicle speed and road information parameters collected by GPS vehicle monitoring system.The functional relationship between the average vehicle speed and the traffic density and the exposure of personnel in high-speed service area was focused when the dangerous goods were in highway transportation.The personnel exposure on roads and at densely populated areas was assessed in real time,and the correction of vehicle type to average speed was considered.The transportation risks were assessed by case study when vehicles were under different speed conditions and passing the service area.Results show that vehicle speed and population density exert significant effects on transportation personnel exposure risks.The proposed model can further decompose risk indicators and improve the accuracy of risk assessment,meanwhile,it can evaluate the dynamic risk of transportation in real time,which has practical significance to assist the intelligent supervision of dangerous goods transportation risk and reduce the transportation risk.
