The invention discloses a method for constructing a method for constructing a road intersection equal-proportion model; and the method comprises the steps: abstracting traffic elements, such as a roadcontour, a lane, an isolation belt, a flow guide island and a pedestrian crossing, into a simple geometric figure according to the spatial features of a road intersection; setting key node space coordinates of various traffic elements, configuring corresponding traffic attributes, and drawing a model consistent with the physical intersection in angle, distance and area. Space and attribute information of the model is stored in a standard and universal text format, and can be looked up and modified on various carriers. The model comprises traffic management attribute characteristics and supports application scene requirements of traffic data analysis, signal control, operation evaluation and the like.

    本发明公开了一种构建道路交叉口等比例模型的方法,该方法包括根据道路交叉口的空间特征,将其中的道路轮廓、车道、隔离带、导流岛、人行横道等交通要素抽象为简单的几何图形,设置各类交通要素的关键节点空间坐标并配置相应的交通属性,绘制出与实物交叉口在角度、距离和面积上相一致的模型。模型的空间和属性信息使用标准、通用的文本格式存储,可以在多种载体上查阅和修改。模型中包含了交通管理属性特征,支持交通数据分析、信号控制、运行评价等应用场景需求。
