摘要: 高速公路运营安全性是实现高速公路高效运营的基本前提,文中采用实时安全可靠度来表征高速公路网管理单元的运营安全性.提出了高速公路网管理单元划分方法.将高速公路网管理单元实时安全可靠度分为静态安全可靠度和动态安全可靠度,采用模糊综合评判方法确定静态安全可靠度,在分析单车行车风险的基础上,采用可靠性图能分析方法确定动态安全可靠度.最后通过算例,对实时安全可靠度的计算方法加以说明.

Abstract:

The operation safety of freeway is the basic prerequisite to the high-efficiency operation. This paper puts forward the concept of real-time safety reliability (RTSR) to characterize the operation safety of management units (MUs) of freeway network. In the investigation, first, the division method of management units is proposed. Next, the RTSR of MUs of freeway network is divided into a static safety reliability and a dynamic one, which are then determined by the fuzzy comprehensive judgment and by the reliability graph analysis based on single-vehicle driving risk, respectively. Finally, an example is presented to expatiate the calculation course of RTSR.
