Functional Requirements

ID	Requirement
1	The vehicle shall provide the capability for a driver to request access to automated vehicle lanes.
2	The vehicle shall request usage of automated lanes for all or part of an overall route; including sending vehicle conditions to the roadside to determine eligibility.
3	The vehicle shall collect and monitor data concerning the safety of the vehicle while on automated lanes including conditions of the brakes, drive train, forward/rear/side sensors, steering condition, fuel level, tire wear and pressure, and the status of vehicle processors and communications.
4	The vehicle shall monitor the area surrounding vehicle in an automated lane to determine the proximity of other objects to the vehicle. Obstacles could include animals, other vehicles, pedestrians, debris in roadway etc.
5	The vehicle shall evaluate the likelihood of a collision between two vehicles or a vehicle and a stationary object, based on the proximity of other objects to the vehicle, conditions of the roadway and environment, and the current speed and direction of the vehicle.
6	The vehicle shall deploy a pre-crash safety system either to avoid the accident or to reduce the accident severity, once it has determined the probability of a collision with the other vehicle or obstacle to be high.
7	The vehicle shall receive automated highway system status, warnings and collision avoidance data (intersection congestion, approaching vehicles, potential collision hazards, etc.) from the roadway field equipment.
8	The vehicle shall send appropriate control actions to the vehicle's accelerator, braking and steering actuators when operating in an automated lane.
9	The vehicle shall exchange data with other vehicles in the platoon to share vehicle status information, roadway condition data, and initiate vehicle actuator controls to maintain safe following distances.
10	The vehicle shall provide warnings to the driver of potential dangers based on sensor input and analysis concerning the safety of the vehicle operating in an automated lane.
11	The vehicle shall present information to the driver in audible or visual forms without impairing the driver's ability to control the vehicle in a safe manner.
