公路网络运营可靠度研究

Study on Operation Reliability of Highwayetwork

首先剖析公路网络运营可靠度与城市道路网络运营可靠度的区别及影响因素,进而对公路网络运营可靠度的内涵进行界定。然后通过对公路路段通行能力的概率分布、均匀分布随机路段通行能力的产生、最短路线辩识、网络平衡配流、路径列出等的研究,建立基于MonteCarlo模拟的公路网络运营可靠度分析方法,并开发MonteCarlo模拟实用程序。最后应用该方法计算了哈尔滨市域公路网运营可靠度。

This paper firstly analyzed the difference and influence factors of highway network and urban road network operation reliability,based on which the highway network operation reliability is further defined.Then the Monte Carlo simulation is applied to highway network operation reliability.Through studying the probability distribution of highway section capacity,the generation of random section capacity with even distribution,the shortest path identification,network equilibrium flow assignment,and path list,this paper established highway network operation reliability analysis method which based on Monte Carlo simulation,the practical program is developed and the Harbin urban road network operation reliability is calculated with the method.
