Exploration of Optimization Method for Road Route Selection in Complex Mountain Areas Based on GIS Technology

针对复杂山区道路选线的优化问题,提出以地理信息系统技术为基础,综合考虑地形特征和环境约束等因素,进行道路选线优化的方法,对道路网络模型进行地形参数的获取与处理,对道路节点及其连通性进行分析;在此基础上,设计多条件权衡算法并有效处理约束条件,以达到道路选线优化的目的。此种方法在实际应用中得到验证并取得了较好的效果。

A method for optimizing road routing in complex mountainous areas is proposed based on geographic information system technology,taking into account factors such as terrain features and environmental constraints.The road network model is used to obtain and process terrain parameters,analyze road nodes and their connectiv-ity,and design a multi condition trade-off algorithm to effectively handle constraint conditions,in order to achieve the goal of road routing optimization.This method has been validated and achieved good results in practical applica-tions.
