摘要
公路养护工作是维持道路正常运行的基本保证,但是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,而对养护作业区长度进行优化设计可以减少这些负面影响。本文对养护作业区长度优化的基本原理、计算方法和优化机理进行了理论探讨。
Highway maintenance is the basic assurance of keeping normal operations of the road. It often needs to close some lanes to set up maintenance work zones. This brings many detrimental effects on traffic flow of the road. Carrying out optimization design for the lengths of maintenance work zones can reduce these negative effects. The basic theory, calculation method and optimization mechanism of the length optimization for work zones are discussed in this paper.
