Multilayer Modeling of Driver Behavior Based on Hierarchical Mode Segmentation
This chapter presents a new hierarchical mode segmentation of the observed driving behavioral data based on the multiple levels of abstraction of the underlying dynamics. By synthesizing the ideas of a feature vector definition revealing the dynamical characteristics and an unsupervised clustering technique, the hierarchical mode segmentation is achieved. The identified mode can be regarded as a kind of symbol in the abstract model of the behavior. Some applications of the proposed model are also discussed.
