摘要: 基于轴载 次数采用蒙特卡罗法计算路面结构可靠度。将路面结构可靠度看作路段连通可靠度,用广度优先搜索方法求出路网连通可靠度。为了将服务水平低的路段 等级提升,利用遗传算法以路网连通可靠度最高为目标进行流量分配,最终提升整个路网的服务水平。并对比流量分配前后的路网连通可靠度与路网服务 水平,给管理者提供参考意见。通过实例表明:遗传算法可以对路网流量进行有效分配。

Abstract: Based on the axial load times, Monte Carlo method was used to calculate pavement structure reliability. Taking pavement structure reliability as road connection reliability, the road network connection reliability was solved by BFS. In order to improve the service level of a road with low service level, the genetic algorithm was used to allocate traffic flow with the target of the highest road network connection reliability. The service level of the whole road network was improved finally. Compared with road network service level and road network connection reliability before and after the traffic flow allocation, manager could acquire some referential advice. The case study shows that genetic algorithm can effectively allocate road network traffic flow.
