1. A lane departure detection computing device for a vehicle configured for autonomous operation, the computing device comprising:

  • one or more processors for controlling operation of the computing device, anda memory for storing data and program instructions usable by the one or more processors, wherein the one or more processors are configured to execute instructions stored in the 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 the vehicle configured for autonomous operation responsive to the determination that one of the first vehicle and the second vehicle is executing a lane departure.
