Interfacing EMME/2 with aimsun2 microsimulation

摘要

Microscopic traffic simulation is a traffic analysis tool that provides a very detailed view of traffic dynamics in road networks, used for very specific purposes of analysis and design of traffic systems. However, the current practice has shown that quite frequently it can also be used either as a complentary tool in transport planning studies, providing a refined dynamic view of sub- networks for a better decision making. Importing data from an assignment exercise into a microsscopic simulator can also be a way of providing some of the default input data required in some cases by the microsimulator. The requirement of interfacing the macro approach on which EMME/2 is based, with the microscopic approach as it has been implemented in AIMSUN2, lead to the development of a specific methodology that has already been tested in some real life projects. This paper presents the recent refinements and improvements to this methodology, and on the design and implementation of the interfaces between EMME/2 and AIMSUN2 based on this methodology. The results are of some applications are presented and discussed.
