Abstract: A computer-implemented method of trajectory prediction includes obtaining a first cross-attention between a vectorized representation of a road map near a vehicle and information obtained from a rasterized representation of an environment near the vehicle by processing through a first cross-attention stage; obtaining a second cross-attention between a vectorized representation of a vehicle history and information obtained from the rasterized representation by processing through a second cross-attention stage; operating a scene encoder on the first cross-attention and the second cross-attention; operating a trajectory decoder on an output of the scene encoder; obtaining one or more trajectory predictions by performing one or more queries on the trajectory decoder.

Abstract: A method of sharing information about an object or a condition on a road includes receiving, by a server from a first autonomous vehicle, a message comprising a first data structure that includes information about a driving condition on a road; and transmitting, by the server to a second autonomous vehicle, a second data structure that includes information about the driving condition on the road, where the second data structure is transmitted in response to determining that a location of the driving condition is related to a trajectory on which the second autonomous vehicle is operating or is expected to drive, where the second data structure is transmitted to the second autonomous vehicle before the second autonomous vehicle reaches the location of the driving condition, and where the server is located in a fixed location outside of the first autonomous vehicle and the second autonomous vehicle.
