Abstract: A vehicle trajectory prediction device is provided. The vehicle trajectory prediction device includes a transceiver, at least one processor, and at least one memory operatively connected with the at least one processor to store at least one instruction causing the at least one processor to perform operations. The operations receive first trajectory data for an ego-vehicle and second trajectory data for at least one neighbor-vehicle, obtain a first feature vector from a first extractor and obtain a second feature vector from a second extractor, obtain an interdependency feature vector between the ego-vehicle and the at least one neighbor-vehicle from a third extractor having mapping data generated by mapping the second feature vector to the second trajectory data as input data, and generate predicted trajectory data of the ego-vehicle from a trajectory generator having the first feature vector and the interdependency feature vector as input data.

Abstract: In some embodiments, a method of providing a user with a roadway route to a destination that maximizes the probability of reaching the destination by a deadline includes providing a database of traffic delay probability distributions based on historical traffic delay information, performing route-planning using at least one of the traffic delay probability distributions and parametric optimization to determine at least one route to the destination that maximizes the probability of reaching the destination by the deadline, and displaying the at least one route to the user.
