Anticipative traffic safety by using microsimulation

Microsimulation is becoming a more useful and powerful tool in the field of ITS applications assessment. In the evaluation process, one of the most important steps is the safety analysis. Actually, classical microsimulation outputs give some helpful information for this purpose, but these aren't sufficient for an accurate and global analysis. Nevertheless, microsimulation allows the knowledge of the vehicles' position, speed and acceleration at any time. Microsimulation also gives appropriate outputs to calculate one or several safety indicators more relevant than those deduced from macroscopic values. This paper explains the concept of a new safety indicator, which not only takes into account the probability but also the gravity of hypothetical collision. This indicator is particularly intended for highways assessments, limited to the linear collision. It gives no information on crossing trajectories conflicts as found at junctions. The paper then presents a case study with the first obtained results (A). For the covering abstract of the conference see ITRD E212343.
