Samenvatting
The need for evaluation of ITS systems requires new modelling tools that allow a detailed modelling of both the roadside and the in-vehicle systems. One of the elements needed is a reliable longitudinal driver model. The requirements of such a model are outlined and the models that are available in the literature are reviewed. The Helly car following model that was previously applied in the MIXIC simulation model is selected as the most appropriate. The use of the model is illustrated by case studies from recent European projects and a Dutch project. For the covering abstract see ITRD E134653.
