By considering the feature of vehicle driving on the event management unit of the freeway corridor, according to the system target, a method to divide the management unit of the road network was put forward. The relative safety braking deceleration was taken as the evaluation index of single-vehicle driving risk. The reliability graph relationship and structure-function between the management unit and subunit were analyzed. Then, dynamic safety reliability and real-time safety reliability were determined on the basis of driving risk. In addition, the queuing and dissipating characteristics of the management unit under traffic incidents were analyzed based on the wave theory. The incident duration and dissipation time were also calculated. At the same time, the travel time prediction model of the incident management unit was set up when the real-time safety reliability was taken as a road resistance function. Finally, an improved travel time prediction model established in this paper is of great significance to improve traffic safety and efficiency, and the research results will provide an important theoretical foundation in the freeway corridor route decision.

基于实时安全可靠性的高速公路走廊行程时间预测模型

考虑到高速公路走廊事件管理单元上车辆行驶的特点，根据系统目标，提出了一种划分路网管理单元的方法。相对安全制动减速度作为单车驾驶风险的评价指标。分析了管理单元与子单元之间的可靠性图关系和结构功能。然后，根据驾驶风险确定动态安全可靠性和实时安全可靠性。此外，基于波动理论，分析了交通事故下管理单元的排队和耗散特性。还计算了入射持续时间和耗散时间。同时，以实时安全可靠性作为道路阻力函数，建立了事故管理单元的行程时间预测模型。最后，本文建立的改进的出行时间预测模型对提高交通安全性和效率具有重要意义，研究结果将为高速公路走廊路线的决策提供重要的理论基础。
