Abstract
A lane departure detection computing device for a roadside device is disclosed. The computing device is configured to execute instructions stored in a memory to: calculate a first path geometry relating to a first vehicle traveling in a first lane; calculate a second path geometry relating to a second vehicle traveling in a second lane different from the first lane; evaluate coextensive portions of the first path geometry and the second path geometry for parallelism; if the coextensive portions of the first path geometry and the second path geometry evaluated for parallelism are not parallel, determine that one of the first vehicle and the second vehicle is executing a lane departure; and operate a vehicle configured for autonomous operation responsive to the determination that one of the first vehicle and the second vehicle is executing a lane departure.
