微观交通模拟是一种交通分析工具，它在通路网络中能提供一个交通动态的详细图形，可用于交通分析和交通系统的设计．目前的实践已经证明它也常被用作交通规划研究中的一个工具，为子网络作出决策提供一个良好的动态依据．将一个分配结果的数据输入到一个微观模拟器中，可以成为某些情形下提供所需要的缺省的输入数据的一个方法．为了将基于EMME／2的宏现方法和基于AIMSUN的微观方法连接起来，发展了一些特殊方法，这些方法已经在实际项目中被试验过．本文介绍了这个方法，以及基于此方法在EMME／2和AIMSUN之间接口的设计和执行的最新进展，并对一些应用结果进行了讨论．
Microcosmic traffic simulation is a traffic analysis tool that provides a detailed graphic of traffic dynamics in a network of routes that can be used in traffic analysis and traffic system design. The current practice has proved that it is also often used as a tool in traffic planning research to provide a good dynamic basis for sub-network decision-making. Entering the data of a distribution result into a microsimulator can be a way of providing the default input data needed in some situations. In order to connect the macroscopic approach based on EMME / 2 and the microscopic approach based on AIMSUN, some special methods have been developed and these methods have been tested in practical projects. This article describes this approach and the recent advances in the design and implementation of interfaces between EMME / 2 and AIMSUN based on this approach, and discusses some of the application results.
