基于路段走行时间可靠性的路网容量可靠性

为了减少了计算工作量，基于路网容量可靠性概念的分析，构造了基于路段走行时间可靠性的路网容量可靠性双层规划模型，根据模型中反映的路径选择行为为用户平衡的特点，用灵敏度分析法求解路网容量可靠性模型，并给出了1个简单的算例．算例结果表明，该模型能够用于评估随机环境下的路网性能，并为路网性能的改善提供依据。

Road Network Capacity Reliability Based on Link Travel Time Reliability

To decrease the amount of calculation, a bi-level programming model based on link travel time reliability was set up for road network capacity reliability through analyzing the concept of road network capacity reliability. Based on the character of route choice shown in the model, i.e. user equilibrium, an algorithm based on the sensitivity analysis was used to solve the model. Finally, a simple numerical example was given. The numerical result shows that the model can be used to estimate the performance of road networks under uncertain environment and provide a way to improve the performance of road networks.
