城市道路复合交叉口交通渠化设计方法研究 总被引:4,自引:0,他引:4
复合交叉口渠化设计对于提高交通服务水平,保证交通安全,解决城市交通拥挤问题有非常重要的意义.以泰州一典型复合交叉口为例,通过多方案的设计及比选,提出了复合交叉口渠化设计的思路、程序和方法,并对所选择的设计方案进行了仿真测试,结果表明所选择的设计方案优于其他备选方案,改善了原有交叉口交通流的紊乱现象.文章所提出的方法对此类交叉口的设计提供了一个参考. 相似文献

A new method of virtual ship assembly modeling which integrates ship three-dimensional design and ship construction planning was described in this paper. A workflow model of simulation modeling based on the virtual ship assembly process was also established; furthermore, a method of information transformation between the ship three-dimensional design and ship construction plan was formulated. To meet the requirements of information sharing between different systems in the ship virtual assembly, a simulation database was created by using the software engineering design method and the relational data model. With the application of this database, the information of ship three-dimensional design, construction planning, and virtual assembly can be integrated into one system. Subsequently, this new method was applied as a tool to simulate the virtual assembly of a ship, and the results guarantee its rationality and reliability. 相似文献
