为探讨现有公路路段交通安全系统可靠度达不到预期要求的问题，利用事故故障树分析方法建立了道路交通安全系统模型，并以其为基础建立了交通安全系统的可靠度分配机制，通过提高少数变量可靠度的故障树方法，达到提高系统总体可靠度，并以道路交通事故发生火灾为例对可靠度进行了分配与计算，结果表明：少数子系统可靠度的提高实现了整个安全系统的可靠度提高，需要提高可靠度的子系统为整个系统中可靠性较低的子系统，在设计上，方法简单、易于操作控制，具有可行性，能够很好的在实际事故安全系统中加以运用。

In view of the existing highway road traffic safety system reliability can not meet the expected reliability, using the accident of the fault tree analysis method to establish model of road traffic safety, traffic safety system is established and on the basis of the reliability allocation mechanism, the reliability of the proposed by raising a few variables to improve the overall re-liability of the method, as a case study of road traffic accident fire for reliability calculation of the distribution and put forward a few variables to improve traffic safety reliability calculation meth-od, the results show that the few of subsystem reliability can im-prove the reliability of the whole security system to improve, need to improve the reliability of subsystem reliability lower sub-system in the whole system, on the design, the method is sim-ple and easy operation control, feasible, can very good in the actual accident security system.
