| 摘 要： | 结合已有的随机选择正向增广路径的方法，提出了3种不同的正向增广路径选择方案；利用Monte Carlo(MC)仿真方法估计出在这3种不同路径选择方案下交通网络中随机饱和流的分布情况.提出了两个评估指标，分析不同路径选择方案下饱和流的稳定性和在满足给定需求下网络饱和流的可靠性.利用实例分析比较了在不同路径选择方案下随机饱和流的分布情况.

| Abstract: | Combined with the existed methods to select the forward directed augmented path randomly, three different selections to the forward directed augmented paths are proposed. A Monte-Carlo simulation approach is utilized to obtain the stochastic saturated flows distribution under various selections to the forward directed augmented paths. Two indices are given to evaluate the stability of the saturated flows and the reliability of the saturated flows under different path selected scenarios. Finally, three examples are used to analyze the stochastic saturated flows distribution under the circumstances of different path selections. |
