Webtive clothoid tentacles [8] and found the parameters of in-terpolating clothoids as an optimisation [9]. The beneﬁts of clothoids for controlling lateral acceleration identiﬁed in [10] can be exploited by unoccupied vehicles, which can travel faster on smooth paths without lateral instabil-ity [11,12]. WebSecondly, we generate a set of clothoid tentacles in the egocentered reference frame related to the ego-vehicle, those tentacles represent possible local trajectories. Thirdly, we modify the evidential grid in order to take into consideration some traffic rules such as safety distance between vehicles.
