In the context of autonomous driving and road situation awareness, this manuscript introduces a Bayesian network that enables the prediction of participant vehicles (PVs) circulating on a highway. The network architecture combines Long-Short-Term-Memory recurrent Deep networks and Support Vector Machines as computational nodes in a graph. The network inputs are real data acquired by radar and synthetic data generated mimicking the real ones. The interaction among multiple vehicles is handled explicitly by introducing the Allowance Factors that model the constraints of the possible interactions of the PVs and the ego car in the trajectory forecast estimation. Results obtained on the conducted tests show the ability of the system to predict the motion of the vehicles up to 6 s in advance with a 92% mean average accuracy. Additionally, if implemented into automatic trajectory planners, the introduced modeling approach enables the prediction and avoidance of possible vehicles’ collisions.

Abstract

In the context of autonomous driving and road situation awareness, this manuscript introduces a Bayesian network that enables the prediction of participant vehicles (PVs) circulating on a highway. The network architecture combines Long-Short-Term-Memory recurrent Deep networks and Support Vector Machines as computational nodes in a graph. The network inputs are real data acquired by radar and synthetic data generated mimicking the real ones. The interaction among multiple vehicles is handled explicitly by introducing the Allowance Factors that model the constraints of the possible interactions of the PVs and the ego car in the trajectory forecast estimation. Results obtained on the conducted tests show the ability of the system to predict the motion of the vehicles up to 6 s in advance with a 92% mean average accuracy. Additionally, if implemented into automatic trajectory planners, the introduced modeling approach enables the prediction and avoidance of possible vehicles’ collisions.
