EMME／2与AIMSUN2微观模拟器的接口

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．

INTERFACING EMME/2 WITH AIMSUN2 MICROSIMULATIOR

Microscopic traffic simulation is a traffic analysis tool that provides a very detailed view of traffic dyamics in road networks, used for very specific purposes of analysis and de-sign of traffic systems. However the current practice has shown that quite frequently it can al-so be used either as a complementary tool in transport planning studies, providing a refined dy-namic view of sub -networks for a better decision making. lmporting data from an asaignment exercise into a microscopic simulator can also be a way of providing some of the default input data required in some cases by the microsimulator. The requiement of interfacing the macro approach on which EMME/2 is based, with the microscopic approach as it has been implamented in AIMSUN 2 lead to the devdopment of a specific methodology that has already been tested in some real life projects This paper prerents the recent refinemects and improvrements to this methodology. and on the design and implementation of the interfaces between EMME/2 and AIMSUN 2 based on this methodology The results are of some applicabons are presented and discussed.
