Abstract
A device receives quantitative data from sensors associated with an autonomous vehicle traveling on a road with other vehicles and from other sensors, and processes the quantitative data, with a first model, to determine distances between the autonomous vehicle and the other vehicles. The device processes the quantitative data, with a second model, to determine relative orientations between the autonomous vehicle and the other vehicles, and generates a conceptual neighborhood graph, based on a third model. The device identifies a subset of the conceptual neighborhood graph, and determines relative trajectories between the autonomous vehicle and the other vehicles based on the distances, the relative orientations, and the subset of the conceptual neighborhood graph. The device determines a decision for the autonomous vehicle based on the distances, the relative orientations, and the relative trajectories, and provides, to the autonomous vehicle, information instructing the autonomous vehicle to implement the decision.
