US Patent 11977385 Obstacle detection based on other vehicle behavior

The disclosed technology provides solutions for vehicle routing and in particular, for facilitating obstacle avoidance maneuvering by an autonomous vehicle (AV). In some implementations, a process of the disclosed technology can include steps for collecting environmental data about an environment around an autonomous vehicle, wherein the environmental data comprises data pertaining to a roadway navigated by the autonomous vehicle and one or more other vehicles navigating the roadway, processing the environmental data to generate an area grid comprising one or more grid sections, wherein each grid section corresponds with a different area of the roadway, and determining a risk-profile for the one or more grid sections based on the environmental data. Systems and machine-readable media are also provided.
