摘要
高速公路的快速发展,迫切需要采用科学合理的养护技术,以延长高速公路的使用寿命。基于高速公路养护管理的建设目标,运用WebGIS、决策支持等技术,以MapGIS K9为二次开发平台,采用Java开发语言,设计并开发了基于MapGIS的高速公路养护决策系统。系统通过专家评价的层次分析法对路面性能进行综合评价;运用线性回归、多项式拟合、时间序列模型、灰色模型等建立路面性能预测模型;针对路面性能评价或预测的结果,利用决策树模型快速提出路面养护处治建议。该系统实现了高速公路养护信息的收集、管理、定位、交互可视化、分析、评价、决策等全流程管理,为公路养护管理提供了可视化与决策支持。
With the rapid development of the highway,it is urgent to adopt the scientific and reasonable maintenance technology to prolong the service life of the highway.Based on the construction goal of highway maintenance management,using WebGIS,decision support and other technologies,taking MapGIS K9 as the secondary development platform,we used Java development language to design and develop a highway maintenance decision system.The system used the AHP method of expert judgment to evaluate the pavement performance comprehensively,and used linear regression,polynomial fitting,time series model and gray model to establish the pavement performance prediction model.According to the results of pavement performance evaluation or prediction,we put forward the suggestions of pavement maintenance treatment quickly based on the decision tree model.This system can realize whole process management of highway maintenance information collection,management,positioning,interactive visualization,analysis,evaluation and decision,and provide visualization and decision support for highway maintenance and management.
