Keywords: speed assistance, traffic safety, simulation model, behaviour
Speed is a crucial issue of road traffic safety. In- vehicle speed assistance systems could affect general mean speed and speed variance, therefore, increase road traffic safety. The purpose of this paper is to contribute to the knowledge concerning the evaluation of safety effects of speed assistance systems by simulation modelling. The paper reviews the state-of-the-art traffic flow models based on literature study. In addition, it discusses limitations of current driving behaviour models. Also, simulation models specifically applied for studying safety effects of speed assistance systems are analysed. Furthermore, the paper addresses some issues concerning safety simulation for discussion, and proposes topics for further research on speed assistance systems.
