KIPDA Regional ITS Architecture

Element Expanded Functional Requirements: Connected Vehicle OBE

Functional Area: Vehicle Intersection Control
  1. The vehicle shall monitor the area surrounding the vehicle as it approaches an intersection to determine the proximity of other objects to the vehicle. Obstacles could include animals, other vehicles, pedestrians, debris in roadway etc.
  2. 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 and the current speed and direction of the vehicle.
  3. The vehicle shall monitor its approach to the intersection and determine if it is approaching the intersection with excessive speed or in an unsafe manner.
  4. The vehicle shall send its current position, velocity, acceleration, direction, and intended turning movement to the roadway field equipment.
  5. The vehicle shall receive warnings and collision avoidance data (intersection congestion, approaching vehicles, potential collision hazards, etc.) from the roadway field equipment.
  6. The vehicle shall provide warnings to the driver about the presence of potentially hazardous situations and need for immediate action.
  7. The vehicle shall send appropriate control actions to the vehicle's braking and steering actuators.
  8. 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 to be high.
  9. 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.
Functional Area: Vehicle Location Determination
  1. The vehicle shall provide the vehicle's current location to other in-vehicle functions.
  2. The vehicle shall calculate the location from one or more data sources including positioning systems such as GPS, sensors that track vehicle movement, and maps used to determine the likely vehicle route.
Functional Area: Vehicle Warning System
  1. The vehicle shall receive vehicle location, speed, and direction information from surrounding vehicles.
  2. The vehicle shall determine vehicle proximity and closing rates and determine the likelihood of a collision.
  3. The vehicle shall warn the driver if the driver should take action to avoid a collision.
  4. The vehicle shall warn the driver of approaching emergency vehicles.
  5. The vehicle shall provide its location, speed, direction, and other information to surrounding vehicles.
  6. The vehicle shall provide its location, speed, direction, and other information to field elements.
  7. The vehicle shall receive warnings from field elements.
