We investigate a utility-based approach for driver car-following behavioral\nmodeling while analyzing different aspects of the model characteristics\nespecially in terms of capturing different fundamental diagram regions and\nsafety proxy indices. The adopted model came from an elementary thought where\ndrivers associate subjective utilities for accelerations (i.e. gain in travel\ntimes) and subjective dis-utilities for decelerations (i.e. loss in travel\ntime) with a perceived probability of being involved in rear-end collision\ncrashes. Following the testing of the model general structure, the authors\ntranslate the corresponding behavioral psychology theory - prospect theory -\ninto an efficientmicroscopic traffic modeling with more elaborate stochastic\ncharacteristics considered in a risk-taking environment. The formulated model\noffers a better understanding of drivers behavior, particularly under\nextreme/incident conditions.\n
