摘要
公路互通立交的型式分类属于非线性系统问题。在分析已有研究成果的基础上,从问题的特征出发,引入非线性映射分析,建立了互通立交型式分类模型。通过非线性映射分析将表征公路互通立交特征的多个指标映射成2个综合指标,按映射值在2维平面中的几何构型可以方便地进行型式分类。该方法物理意义明晰,利用DSP(Data Processing System)软件系统进行计算便捷高效,分类结果表达方式直观。案例分析表明,分类结果符合工程实际。
Interchange type classification is a nonlinear system.Therefore,nonlinear mapping analysis was introduced to study the problem.In the process of classification,multiple attributes which express the characteristics of interchange project were directly mapped into two comprehensive indexes by Data Processing System.The results can be gained by judgment of relative locations of objects in two dimension coordinate system.The method is recommended for its clear modeling,tangible physical significance,objective and effective. An example is employed to demonstrate how to use the proposed method.
