摘要
提出了运用微观交通仿真软件Vissim对公路养护作业区建模、分析和评价的流程,在示例中对其进行了验证。选择平均延误作为指标,定量分析和评价了交通流量、大型车比例、坡度等因素的影响,建立了回归预测方程。
The process of modeling, analysis and evaluation for highway maintenance work zone is proposed using microscopic traffic simulation software Vissim. It is demonstrated through a case study. The measure of average delay is selected here. The impacts of three factors on delay including traffic volume, percentage of heavy vehicles and grade are analyzed and evaluated quantitatively. And the regression prediction equation is established between average delay and three factors.
