为了定量分析沥青路面不同养护措施的养护效率,通过采用VISSIM交通仿真的方法建立不同的养护方案模型,对交通量、工作区长度及时间的不同变量水平进行交通仿真,得出行程延误、排队长度等指标并进行分析。分析发现采用新型养护技术,可以缩短工作区长度及封闭车道时间,降低车辆延误,缩短排队长度,能够达到快速养护的目的,同时,VISSIM仿真也为养护效率的定量评价提供了方法。
In order to quantitatively analyze the conservation efficiency of different curing measures for asphalt pavement, different maintenance schemes were established by using VISSIM traffic simulation model. Traffic simulation, traffic length and different variable levels of working area were simulated by traffic simulation, and the travel delays, queuing length And other indicators and analysis. The analysis shows that the new maintenance technology can shorten the length of the work area, close the lane time, reduce the vehicle delay and shorten the queue length so as to achieve the purpose of quick curing. At the same time, the VISSIM simulation also provides a method for the quantitative evaluation of conservation efficiency.
