| 摘 要： | 公路养护工作是维持道路正常运行的基本保证,设置养护作业区往往需要封闭部分车道,这常会给道路上的交通流带来不利影响,对养护作业长度进行优化设计可以减少这些负面影响。在考虑道路交通流量的时间变化特性基础上建立了养护作业费用模型,利用Matlab工具初步实现了在道路交通流随时间变化情况下的作业区长度优化计算,并给出了具体算例。

| Abstract: | Road maintenance is the basic assurance of keeping normal operations of the road,which often requires closing some lanes to set up maintenance work zones and thus has negative effects on traffic flow.The negative effects can be reduced by optimal design on the lengths of the maintenance work zones.A road maintenance delay costs model was presented by considering the time variation.The Matlab was used to calculate the lengths of the optimal work zone under the variable traffic flow.A numerical example is als... |
