Abstract
In this paper an approach for a traffic state network monitor NEMO is described as it was developed in the project Munich-COMFORT. Its aim is to describe the traffic state in urban and rural areas in terms of traffic classes. Together with the tool STRAMA, an evaluation of the traffic state in case of changes in the traffic demand and/or traffic network supply can be investigated. These tools were used in the project TABASCO in order to determine and evaluate appropriate strategies for alternative collective route guidance by taking into account the traffic state in the whole traffic network, i.e. the urban and the interurban network.
