leg intersection造句

• Three - leg intersection
  三路交叉
• The subject of this dissertation is three - leg intersections with unsignalized control in highway system . there are two main objectives : one is to discuss crashes statistical characteristics and carry out a method to predict safety performance . the second one is that make further discussion on crashes inherent mechanism , especially on relationship between of driving behavior , waiting time and acceptance gap
  本文研究的目的主要有两个:一是探求交叉口事故的统计特性,提出预测交叉口安全性能的模型;二是在这个模型的指引下,进一步在理论上探讨交叉口事故和违章的机理,重点探讨可接受间隙、等候时间与驾驶行为三者之间的关系,从视距设计、控制和管理对策上提出避免高危驾驶行为的设计方法。
• By using visual basic 5 . 0 language , activex automation interface , the oop technology and developing autocad 2000 , the system not only can achieve the horizontal design and the vertical design of three - legs and four - legs intersection at the tangent section and the curved section , but also can calculate earthwork based on digital terrain model
  本系统以vb5 . 0为开发工具，采用面向对象的编程方法，利用activex自动化技术，通过对autocad2000的二次开发，可以进行处于直线路段、曲线路段的三路、四路交叉口的平面设计和立面设计与绘图，完成基于数字地面模型的工程数量计算。
