摘要: 为了给基于GIS-T的交通仿真平台提供数据支持,构建了基于GIS-T路网数据模型,增强了对交通规则和路面标线描述;在数据模型的基础上,量化了线性参考系统截取量,给出了GIS-T路网单元的构造方法,包括车行道分界线和路面的构造方法;提出有向子路段是保证子路段几何完整性的基本单元,给出路网构建流程;构建了一个典型的十字交叉口,并把构建的路网转换成Paramics和Vissim仿真路网,验证了GIS-T路网在交通仿真中应用的可行性。对比GIS-T路网与仿真路网,得到GIS-T路网在描述交通规则和标线方面的优势。

Abstract: In order to provide road network data for traffic simulation platform on the base of GIS-T, a GIS-T road network data model was created. The model put the emphasis on the description of traffic rules and road markings. On the basis of data model, a quantified cut method for linear referencing was proposed and the method was adopted to create road network element, such as lane boundary and road surface. Furthermore, the carriageway was regarded as the unit to keep the shape of road segment, and flow of building a road network was put forward. An intersection was created by the editor tool and the road network was transferred into the road network of Paramics and Vissim. Experimental results show that the data mode application is feasible in traffic simulation. In comparison with the other two simulation road network, it implies the advantage of the GIS-T road network data model in presenting road markings and traffic rules.
