Abstract
In this report, results of the research project 'Traffic flow operations during congestion' have been reported, the aim of which was to identify issues relating to current problems encountered in Dutch application studies, current state-of-the-art concerning empirical and theoretical knowledge on traffic flow operations during congestion, and how this knowledge is currently implemented in traffic flow models. Also, the views of national and international experts concerning issues in congested traffic flow operations and modelling were included in the research. Finally, data requirements for additional research concerning congested traffic flow operations were investigated. (Author/publisher)
