摘要
为准确辨识公路运输通道内影响运输安全的关键节点和路段,以现有路网节点和路段的脆弱性评估指标为基础,建立公路运输通道的脆弱性评估模型。基于Arc GIS平台,采用Python脚本语言,实现了公路运输通道脆弱性可视化分析。通过算例分析,验证了该方法的可行性和评估模型的有效性。
In order to identify the key nodes and road section in road transport corridor which may affect the safety of the transportation,this paper builds the vulnerability of the assessing model by using road network vulnerability assessment indexes. The vulnerability analysis application is developed to visualize the road transport corridor by using Arc GIS platform and Python language. Case analysis verifies the feasibility of the method and the validity of the assessing model.
