Object state tracking and prediction using supplemental information

A method of predicting a state of an object detected within a vicinity of a vehicle, comprising:

• detecting, at a plurality of discrete times [t, t−1, t−2, . . . ], a respective plurality of states of the object;
• obtaining, based at least in part on a present location of the vehicle, supplemental information, associated with an environment of the present location, that indicates at least a speed reduction factor;
• executing a prediction operation to determine a predicted state of the object at a time t+1 based at least in part on the detected plurality of states and the supplemental information;
• determining an actual state of the object at a time t+1;
• and
• modifying the prediction operation based at least in part on the actual state.

A non-transitory computer-readable medium for predicting a state of an object detected within a vicinity of a vehicle and including instructions that when executed by one or more processors cause the one or more processors to:

• detect, at a plurality of discrete times [t−2, t−1, t, . . . ], a respective plurality of states of the object;
• obtain, based at least in part on a present location of the vehicle, supplemental information, associated with an environment of the present location, that indicates at least a speed reduction factor;
• execute a prediction operation to determine a predicted state of the object at a time t+1 based at least in part on the detected plurality of states and the supplemental information;
• determine an actual state of the object at a time t+1;
• and
• modify the prediction operation based at least in part on the actual state.
