摘　　要：首先对道路在交叉口处的结构、关系和交叉口空间形态进行了讨论。在此基础上,提出了对异态道路进行选择性可视化时使用路口封闭线来模拟道路红线的具体方法,并对实现过程中使用的逻辑计算模型和数据存储结构提出了有效解决方案。The research is intent to study on how to determinate the ascription of the planar crossway section and the relative technology for define and expend its semantic mode when look the urban road as one certain spatial occupancy.The research starts at a series of the study on the road structure and relationship between roads in the crossway section and the spatial configuration of crossway.Then the article proposes use close-line to simulate road redline when visualizing selected heterogeneous road.The article also provides necessary solutions on the logistic model and data structure for that.
