Intersection design is an important part of city road design 摘要交叉口设计是城市道路设计的重要组成部分。
A highway intersection designed to permit traffic to move freely from one road to another without crossing another line of traffic 互通式立体交叉一种设计的使车辆不用穿过另一条线的车辆就可以从一条路到另一条的交叉路口
This paper , with a view to improving city intersection traffic and safety , serves as an attempt to optimize the existing city intersection design 为了提高城市道路平面交叉口通行能力和确保安全的前提下,对现有交叉口优化设计上进行了有益的尝试,取得了良好的效果。
An example shows that the core models are consistent with the characteristics of chinese urban roads and the efficiency of plane road intersection design can be improved greatly 应用实例表明该系统内核模型符合我国道路交通的实际情况,能大大提高道路平面交叉口设计的效率。
The system can achieve contour lines and elevations of the pavement board corners with the establishing of face models seriesly or one by one based on dynamic mutual techmology . the application system also has some small drawing and editting tools for the plane intersection design 系统使用动态交互技术,通过批量和单元face模型板块的建立,实现了等高线和板块板角高程的自动输出,系统也扩展了平交口平面设计中的一些绘图编辑工具。
The design achievements has little effect to guide and discipline the construction . after studying the reasonable division of the labor between person , drawing flatbed and application program , the author developed " the intersection application system " with the using of visual c + + , autocad and objectarx , which is also based on the traditional theory of the vertical intersection design 作者充分研究了平面交叉口设计中人、图形平台及辅助设计系统的合理分工,并基于传统的立面设计理论和方法,以visualc + +为编程工具, autocad为图形平台,使用objectarx二次开发工具,编制了本平交口辅助设计系统。
It includes geometric design , traffic organization design and signal timing of signalized intersection . the techniques of expert system and computer - based simulation are employed . several schemes that are generated from expert system of signalized intersection design are inputted into microscopic simulation system , and then optimal scheme is put forth 本文研究了城市道路信号交叉口的优化设计方法,具体的研究过程是:利用专家系统技术,从几何设计、交通组织设计以及信号配时等三方面对信号交叉口进行优化设计,然后利用微观计算机仿真技术对优化方案进行评价。
The intersection design is very important . but in the vertical design , the designer could n ' t use the form of contour lines to express accurately his design intension . he could only write few elevations of the pavement board corners because of the complexity in design progress and the bother in calculation 平交口立面设计,由于其设计过程复杂和计算麻烦,设计者很难以等高线等形式来准确地表达设计意图,只能是稀疏地手工计算标注若干高程控制点,设计成果对施工的指导及约束作用远不能满足要求。
