Abstract: Disclosed is a modular stochastic machine capable of carrying out probability calculations and including: at least one stochastic distribution module corresponding to a plurality of random variables and capable of receiving an input of values of specified variables in order to return, as output, a representation of the distribution of at least one non-specified variable determined by the values of the specified variables; and at least two stochastic variable modules each corresponding to a single random variable and including: both a stochastic multiplier capable of receiving, as input, representations of distributions in order to return, as output, a representation of the product distribution, as well as a stochastic proportional normalizer capable of receiving, as input, a representation of a distribution in order to return, as output, a proportionally normalized representation.

Abstract: The invention relates to a vehicle or traffic control method and to a vehicle or traffic control system. The vehicle or traffic control method comprises the steps: a) estimating actual and/or future behavior of a first traffic participant and of a second traffic participant, respectively, the second traffic participant being different from the first traffic participant, b) estimating a trajectory to be taken by the first traffic participant and/or a trajectory to be taken by the second traffic participant, c) determining risk of collision of the first traffic participant relative to the second traffic participant by calculating information adapted for risk assessment of collision of the first traffic participant relative to the second traffic participant, and d) controlling the behavior of the first traffic participant based on the information provided after step a), step b) and/or step c).
