基于跟踪车辆的隧道运营危害风险研究

为分析交通事故尤其是危险品运输事故对隧道运营带来的潜在危害风险,首先,通过改进个人风险接受准则法对隧道运营危害风险进行量化,假定隧道同时只发生1 次交通事故,将事故造成的危害分为原发性危害和次生性危害,建立隧道运营危害计算模型,对不同跟踪车所造成的司乘人身危害风险进行评估。然后,对实际案例进行分析。分析案例结果表明: 1)在高峰小时,有危险品运输情况下隧道运营危害提高22. 05%,说明隧道中混合车流会极大提高隧道运营的不安全性; 2)次生性危害增长尤为显著, 故危险品运输车事故对跟踪车辆带来的二次事故后果更加严重。最后,据此提出隧道运营组织的相关建议。

Research on Hazard Risk of Tunnel Operation Based on Tracking Vehicle

The paper is to analyze the potential hazard risk of tunnel operation caused by traffic accidents, especially dangerous goods transport accidents. Firstly, the risk of tunnel operation hazard is quantified by improving the personal risk acceptance criteria method. It is assumed that the tunnel has only one traffic accident at the same time, and the damage caused by the accident is divided into primary hazard and secondary hazard. The tunnel operation hazard calculation model is established to evaluate the risk of personal injury caused by different tracking vehicles. Then the results show that: (1) In the peak hours, the hazard risk of tunnel operation increases by 22. 05% in the case of dangerous goods transportation, which indicates that the mixed traffic flow in the tunnel greatly increases the insecurity of the tunnel operation. (2) The secondary hazard growth is particularly significant, so the secondary accidents of the tracking vehicles caused by the accidents of the dangerous goods transport vehicles are more serious. Finally, the relevant recommendations of the tunnel operation organization are proposed.
