基于GIS成本路径的智能道路规划
|
摘要
为解决传统的道路选线过分依赖于设计专家的经验与知识,难以获得统一的科学决策方案且时效性较差的问题,基于地理信息系统,选取昆明市与曲靖市之间的区域作为研究区,提出了一种基于地理信息系统(GIS)成本路径的智能道路规划模型。首先综合考量土地利用、坡度、坡向、高程、起伏度5个单因素,并根据Dijkstra最短路径算法依次生成各单因素成本路径。其次利用层次分析法确定各单因素的权重,并通过叠置分析生成综合因素最优成本路径。最后,从经济、生态与人文等角度进行评定,得到最优成本路径道路规划方案。该智能道路规划模型提高了原有道路规划方法的科学性与时效性,具备一定的参考价值。
This paper aims to solve the problem that the traditional road routing relies too much on the experience and knowledge of design experts,which makes it difficult to obtain an unified scientific alternative and also inefficient to work.Based on geographic information system,this paper selected the area between Kunming City and Qujing City as the research area,and put forward an intelligent road planning model based on GIS cost path.First of all,we considered the five single factors of land use,slope,slope aspect,elevation and relief,and then generated the cost oath of each single factor by means ofthe Dijkstra's shortest path algorithm.Then,the weight of each single factor was determined by analytic hierarchy process,and the optimal cost path of the comprehensive factor was produced by overlay analysis.Next,the optimal cost path road planning scheme was obtained from the economic,ecological and human perspectives.The intelligent road planning model improved the scientificness and timeliness of the original road planning method,and has certain reference value.
