基于HDM的云南地方公路网级养护规划分析

Analysis on the Road Network Program of Yunnan Province Based on HDM

公路路网养护规划是公路养护策略制定和选择的主要依据,也是养护资金合理使用、路段养护优先级排序的主要依据。目前路网级养护规划并没有得到管理部门的重视,结果导致公路养护资金的使用效率低下、公路养护决策比较随意的问题十分突出。基于HDM详细阐述了公路路网养护规划制定的流程,其中EIRR是路网级养护规划的主要经济指标,道路用户广义费用、管理部门管理费用等作为参考指标。在进行网级养护规划后评估时,需要对规划后不同因素导致的EIRR的变化、机动车的预估运行速度以及碳排放等几个指标进行综合分析和评估,验证养护规划的合理性与有效性。

Road network maintenance programming is the main basis of the decision of the road maintenance strategies,meanwhile is the basis for the proper use of maintenance cost and the maintenance ranking of road sections.The road administrator does not pay more attention on the maintenance programming in China,which results in ineffective use of maintenance cost and arbitrary maintenance decisions.In the paper,the procedure of preparing road network programming is explained based on HDM,and EIRR is the main index,the others indexes such as user cost and the overhead expense of the administration departments are reference index.When carrying out post evaluation of the maintenance programming,the change of EIRR,the motor traffic speeds and carbon emissions should be comprehensively analyzed and evaluated so as to testify the rationality and effectiveness of the maintenance programming.
