Abstract
Systems and methods described herein relate to providing guidance to vehicle drivers regarding predicted lane-change behavior of other drivers. One embodiment transforms historical vehicle trajectory data into a corresponding alternative representation; applies a clustering algorithm to group a plurality of drivers into groups of similar drivers; applies Bayesian inference to train a Bayesian neural network (BNN) for the drivers in each group; adapts the BNN for each group to generate a personalized BNN for each driver in that group; identifies a particular driver on a roadway; receives information regarding the particular driver's vehicle and one or more other nearby vehicles; estimates a probability that the particular driver will change lanes using the personalized BNN for that driver; and communicates guidance regarding predicted lane-change behavior of the particular driver to at least one nearby vehicle based, at least in part, on the estimated probability that the particular driver will change lanes.
