随着大城市交通问题的日益加剧,计算机辅助分析软件已经成为交通规划与设计项目中不可或缺的工具。由德国PTV公司开发的PTV·Vision(“Vision”意指交互式网络优化的图形信息系统)是一组用于交通规划和交通工程设计的软件,适用于从区域交通需求建模与预测到交叉口的详细分析和仿真,即从宏观到微观的整个交通规划过程,因此该软件具有较强的实践应用价值。
With the increasing traffic problems in big cities, computer-aided analysis software has become an indispensable tool in transportation planning and design projects. PTV · Vision (“Vision” means an interactive network-optimized graphical information system) developed by PTV in Germany is a group of software for traffic planning and traffic engineering designed to track and analyze traffic demand from regional to intersecting The detailed analysis and simulation of the mouth, that is, the entire traffic planning process from the macro to the micro, therefore, the software has strong practical value.
