本研究提出一个考虑驾驶员路径选择行为和维修的路面寿命周期成本（LCC）评估模型。假设驾驶者改变其路线选择，是因为路面状况恶化导致的驾驶成本变化，以及路面维修工程导致的交通容量变化。LCC最小化问题被表示为隐式规划，其中LCC最小化服从基于概率的随机用户均衡（PSUE），该PSUE表示驾驶员的路径选择。最后给出了应用灵敏度分析技术求解PSUE的LCC最小化问题的算法。最后给出了利用该测试网络得到的简单数值结果。
This study proposes a model for evaluating life-cycle cost (LCC) for pavements considering both driver's route choice behavior and repair. It is assumed that drivers change their route choices because of both the change in driving cost brought about by the deterioration of surface conditions on pavements and the change in traffic capacities due to repair work on pavements. The LCC minimization problem is formulated as the implicit program, in which LCC is minimized subject to the probit-based stochastic user equilibrium (PSUE), which expresses drivers’ route choices. The solution algorithm for the LCC minimization problem developed by applying the sensitivity analysis technique for the PSUE is also presented. Last, the simple numerical results obtained by using the test network are shown.
