摘要：	Within the area of transport telematics, systems like adaptive cruise control systems (ACC-Systems), early warning systems, intelligent control systems for variable speed limitation, ramp metering systems are developed or improved. Recently ACC-Systems are launched into the market, so the penetration rate will be increase in the future. ACC-Systems was researched very detailed by using of microscopic models or by field tests with limited number of equipped vehicles. The expected impacts of this systems on the traffic flow was shown by microscopic analysis for different penetration rates. Because macroscopic models are able to simulate the traffic within real time, these models are using within model based traffic management systems instead of microscopic models. But macroscopic models are cannot model the effect of systems like adaptive cruise control, which have an direct effect on microscopic variables. What are missing now are methods for modelling the impacts of such systems on the traffic flow on the level of macroscopic modelling to be able to consider these impact within traffic management systems. Therefore in this contribution an existing macroscopic traffic flow model (SIMONE – SImulation of MOtorway NEtworks) will be extended with suitable macroscopic terms to be able to consider the impact of these systems on the traffic flow.
